tft display vs super amoled in hindi brands

Thanks for the display technology development, we have a lot of display choices for our smartphones, media players, TVs, laptops, tablets, digital cameras, and other such gadgets. The most display technologies we hear are LCD, TFT, OLED, LED, QLED, QNED, MicroLED, Mini LED etc. The following, we will focus on two of the most popular display technologies in the market: TFT Displays and Super AMOLED Displays.

TFT means Thin-Film Transistor. TFT is the variant of Liquid Crystal Displays (LCDs). There are several types of TFT displays: TN (Twisted Nematic) based TFT display, IPS (In-Plane Switching) displays. As the former can’t compete with Super AMOLED in display quality, we will mainly focus on using IPS TFT displays.

OLED means Organic Light-Emitting Diode. There are also several types of OLED, PMOLED (Passive Matrix Organic Light-Emitting Diode) and AMOLED (Active Matrix Organic Light-Emitting Diode). It is the same reason that PMOLED can’t compete with IPS TFT displays. We pick the best in OLED displays: Super AMOLED to compete with the LCD best: IPS TFT Display.

New Delhi: The technology used in mobile displays in the modern day smartphones has progressed significantly. In the era of touchscreen  smartphones, the display technology has become one of its primary selling points, and certainly its most unique feature. Not only we want the touch screens to offer crisp text, vibrant images, blur-free video and enough brightness, we want them at low cost too.

For instance, HTC One uses Super LCD3 tech, in its 4.7in screen which gives a resolution of 1920 x 1080 pixels, with pixel density of 469 pixels per inch (ppi). This results in super display in terms of crispness and colour reproduction. HTC says the SLCD technology gives the phone better power management, improved viewing angles and is easier to produce.

Here we"ve rounded up all the important information about different mobile screen types below, so you"ll know what to look out for on your next phone.

The Thin film transistor liquid crystal display (TFT LCD) technology is the most common display technology used in mobile phones. A variant of liquid crystal display (LCD), the technology uses TFT technology to enhance image quality. It offers better image quality and higher resolutions as compared to earlier generation LCD displays.

IPS LCD Stands for In Plane Switching liquid Crystal Display. This technology offers better display quality as compared to the TFT-LCD display. The good part about IPS LCD is that it offers better viewing angles and consumes less power. Due to higher costs, it is found only on high-end smartphones. Apple uses a high resolution (640x960 pixels) version of IPS LCD in its iPhone 4, which is also called Retina Display.

Organic Light Emitting Diode (OLED) display technology is much better as compared to the LCD display technology because of its excellent colour reproduction, faster response times, wider viewing angles, higher brightness and extremely light weight designs.

OLEDs are brighter than LEDs and do not require backlighting like LCDs. Since OLEDs do not require backlighting, they consume much less power than LCDs.

Since these display forms are easier to produce, they can be made to larger sizes. Because OLEDs are essentially plastics, they can be made into large, thin sheets.

AMOLED stands for Active Matrix Organic Light Emitting Diode. A step ahead of OLED screens, the AMOLED screens can control each pixel individuality while maintaining the properties of an OLED panel. AMOLED screens use a different subpixel arrangement which can reduce the image quality a bit.

AMOLED screens have all the attributes of an OLED display like excellent colour reproduction, faster response times, wider viewing angles, higher brightness and extremely light weight designs.

Super AMOLED display technology is an advanced version of AMOLED display. Samsung uses this term for the AMOLED panels that they develop. Super AMOLED  screens are built with capacitive touch sensors on the display itself. Super AMOLED display is much more responsive than an AMOLED display. Samsung top-of-the-line Galaxy SII comes engineered with Super AMOLED display technology. Samsung has already took it"s SMOLED screen to next levels by developing Super AMOLED+, HD Super AMOLED+ and FHD Super AMOLED+ screens.

It is a name given by Apple to the high-resolution screen technology introduced on the iPhone 4 in June 2010. Something is a Retina Display when it offers a density of pixels above 163 pixels per inch. The company calls it the Retina display because its pixels cannot be individually identified by a human eye, thus rendering a super sharp display, more crisp text and more clear pictures.

Retina Display is designed to smooth the jagged edges of pixels are provide a higher-quality image than previously available on mobile devices. Apple claims that its resolution is so good that it makes it impossible for the human eye to distinguish individual pixels. Its effects shows up in text, images and videos.

Color boost is simply Moto"s marketing term for their new display. Although it now uses LCD displays, the company fine-tuned its panels to match the saturation of OLED displays while maintaining the higher performance of LCD. It"s somewhere in the middle ground.

Over time, the purpose of using mobile phones or Smartphones has changed. Comparatively, it has now become a basic necessity of every individual. Smartphone has dramatically transformed the lives of individuals. It has now become a mini-computer that everyone carries in their pocket. Instead, you can have multiple things at your fingertips in a few seconds. While there are plenty of things to look for, AMOLED vs OLED is also a part of it.

Before purchasing any Smartphone, everyone goes through a list of specifications. This list includes display type, screen size, battery backup, supported operating system, total internal memory, and many others. Today, we have brought a comprehensive study of the significant display technologies available nowadays.

This article will introduce you to AMOLED vs OLED display technologies. Then, we will discuss the properties of both display technologies, followed by the difference between AMOLED vs OLED.

It stands for Natural Light-Emitting Diode, a type of LED technique that utilises LEDs wherein the light is of organic molecules that cause the LEDs to shine brighter. These organic LEDs are in use to make what are thought to be the best display panels in the world.

When you make an OLED display, you put organic films among two conductors to make them. As a result, a bright light comes out when electricity is used—a simple design with many advantages over other ways to show things.

OLEDs can be used to make emissive displays, which implies that each pixel can be controlled and emits its very own light. As a result, OLED displays have excellent picture quality. They have bright colours, fast motion, and most importantly, very high contrast. Most of all, “real” blacks are the most important.  The simple design of OLEDs also makes it easy to create flexible displays that can bend and move.

PMOLED stands for Passive Matrix Organic Light Emitting Diode. The PMOLEDs are easy to find and much cheaper than other LEDs, but they cannot work for a long duration as their lifespan is very short. Therefore, this type of display is generally for small devices up to 3 inches.

AMOLED stands for Active Matrix Organic Light Emitting Diode. This type of display is generally for large platforms. It contains TFT, which further consists of a storage capacitor. It also works on the same principle as OLED displays.

AMOLED offers no restriction on the size of the display. The power consumption of AMOLED is much less than other display technologies. The AMOLED provides incredible performance. It is thinner, lighter, and more flexible than any other display technology like LED, or LCD technology.

The AMOLED display is widely used in mobiles, laptops, and televisions as it offers excellent performance. Therefore, SAMSUNG has introduced AMOLED displays in almost every product. For example, Full HD Super AMOLED in Samsung Galaxy S4 and Samsung Galaxy Note 3, Super AMOLED in Samsung Galaxy S3, HD Super AMOLED in Samsung Galaxy Note, and HD Super AMOLED Plus in Samsung Galaxy S3. Apart from this, it is also used in AMOLED vs OLED creating the following:

So far, we have discussed OLED and AMOLED display technologies. Now, we will look at some of the differences between OLED and AMOLED display technology:

OLED comprises thin layers of the organic component, which emits light when the current passes through it. In this technology, each pixel transmits its own light. On the other side, AMOLED consists of an additional layer of thin-film transistors (TFTs). In AMOLED, the storage capacitors are used to maintain the pixel states.

While the technology is different among various manufacturers, Samsung’s edge AMOLED displays use plastic substrates with poly-Si TFT technology similar to how LG uses it in their POLED technology. This technology is what makes the possibility to build curved displays using an active-matrix OLED panel.

OLED display much deeper blacks as compared to the AMOLED displays. You cannot see the screen in AMOLED display under direct sunlight. The AMOLED display quality is much better than the OLEDs as it contains an additional layer of TFTs and follows backplane technologies.

The OLED devices are simple solid-state devices consisting of a thin layer of organic compounds in an emissive electroluminescent layer where the electricity generates.

These organic compounds are present between the protective layers of glass or plastic. Comparatively, AMOLED comprises an active matrix of OLED pixels along with an additional layer of TFTs. This extra layer is responsible for controlling the current flow in each pixel.

The OLED display offers a high level of control over pixels. Hence, it can be turned off completely, resulting in an excellent contrast ratio compared to the AMOLED displays and less power consumption. On the other side, AMOLED has faster refresh rates than OLEDs. Also, they offer a tremendous artificial contrast ratio as each pixel transmits light but consumes more power than OLEDs.

OLED displays are comparatively much thinner compared to the LCDs. Hence, it provides more efficient and bright presentations. In addition, OLED offers support for large display sizes compared to the traditional LCDs. AMOLEDs remove the limitation of display sizes. one can fit it into any display size.

Putting all the points mentioned above in view, the key difference to understand appropriately is that POLED is an OLED display with a plastic substrate. On the other hand, AMOLED is Samsung’s word for its display technology which is mainly for marketing. Therefore, most phone manufacturers having AMOLED displays mean that they are using Samsung displays. It is as simple as that. To add to that, all the curved display technology is made possible because of the usage of plastic substrate.

So, based on the points mentioned above, the difference between OLED and AMOLED displays, you can choose any of the two display technology at your convenience. Both are good, offer excellent performance, and are customised according to your requirements.

The AMOLED display has a higher quality than OLEDs since it has an additional layer of TTs and uses backplane technologies. When compared to OLED screens, AMOLED displays are far more flexible. As a result, they are substantially more expensive than an OLED display.

Window to the digital world, the display is one of the first seen features when selecting a smartphone, so a show must be good, and an AMOLED display offers the same. Offering a great viewing experience, here are the top 3 AMOLED screen smartphones available in the market right now:

Smartphone displays have advanced significantly in recent years, more so than most people realise in this technological age. Display screens are similar to windows in the mobile world, which has seen a tremendous transformation in innovative products in the last several years. People have gotten more selective when buying a phone in recent years, and although all of the functions are important, the display is always the most noticeable.

Major smartphone manufacturers attempt to provide their consumers with the most delicate devices possible that incorporate the most up-to-date technologies. In AMOLED vs OLED, AMOLED is a type of OLED and a more prominent example of both OLED and POLED, so there’s no debate about which is superior.

The demand for the best visual experience has grown higher over recent years. Everyone wants the best in the class display to their smartphones to view the high-definition magic their phone provides. This demand for better display has risen recently as big brands like iPhone and Samsung have added some absolutely gorgeous displays to their smartphones.

The major battle begins here. The two competitors of the game are LTPS LCD and AMOLED. These are state of the art displays and people often find themselves comparing these two displays. People are wondering about the result for LTPS vs AMOLED.

LTPS and AMOLED comparison has always been an interesting debate. Potential buyers of smartphones keep comparing the difference between LTPS and AMOLED. There is a complete LTPS and AMOLED comparison below which outlines the difference between these two types:

LTPS stands for Low-Temperature PolySilicon. This type of display provides a faster and more integrated display compared to a standard LCD. The LTPS display provides a better picture quality for the user and some people consider it to be more true to life. It provides larger picture densities and is also lower on power consumption as it does not light up every pixel individually. People can expect a higher picture resolution in their displays.

AMOLED stands for Active Matrix Organic Light Emitting Diode. AMOLED displays are completely different. They use an array of LEDs that help light up every pixel individually, so the only area of the display that is in use, only those pixels light up and the others stay shut. This helps provide a higher contrast to the image with very deep blacks. The display also helps in power consumption as every pixel draws power individually.

There is no actual winner to this debate, just like the console war or the Android vs Apple debate. The choice depends completely on the user and their tastes and preferences. If the users want a better picture resolution in their display, they can go with LTPS LCD and if the user wants a higher contrast picture to their display then they can go with AMOLED. Both displays deteriorate faster than standard LCD screens. Apple is known to use LCD panels in their smartphones and Samsung is known to use AMOLED ones. These are the points that can help the user make an informed decision about which display they would want to go with.

The world of smartphones has been busy for the past few months. There have been numerous revolutionary launches with groundbreaking innovations that have the capacity to change the course of the smartphone industry. But the most important attribute of a smartphone is the display, which has been the focus for all prominent players in the mobile phone industry this year.

Samsung came up with its unique 18:5:9 AMOLED display for the Galaxy S8. LG picked up its old trusted IPS LCD unit for the G6’s display. These display units have been familiar to the usual Indian smartphone buyer. Honor, on the other hand, has just unveiled the new Honor 8 Pro for the Indian market that ships with an LTPS LCD display. This has led to wonder how exactly is this technology different from the existing ones and what benefits does it give Honor to craft its flagship smartphone with. Well, let’s find out.

The LCD technology brought in the era of thin displays to screens, making the smartphone possible in the current world. LCD displays are power efficient and work on the principle of blocking light. The liquid crystal in the display unit uses some kind of a backlight, generally a LED backlight or a reflector, to make the picture visible to the viewer. There are two kinds of LCD units – passive matrix LCD that requires more power and the superior active matrix LCD unit, known to people as Thin Film Transistor (TFT) that draws less power.

The early LCD technology couldn’t maintain the colour for wide angle viewing, which led to the development of the In-Plane Switching (IPS) LCD panel. IPS panel arranges and switches the orientation of the liquid crystal molecules of standard LCD display between the glass substrates. This helps it to enhance viewing angles and improve colour reproduction as well. IPS LCD technology is responsible for accelerating the growth of the smartphone market and is the go-to display technology for prominent manufacturers.

The standard LCD display uses amorphous Silicon as the liquid for the display unit as it can be assembled into complex high-current driver circuits. This though restricts the display resolution and adds to overall device temperatures. Therefore, development of the technology led to replacing the amorphous Silicon with Polycrystalline Silicon, which boosted the screen resolution and maintains low temperatures. The larger and more uniform grains of polysilicon allow faster electron movement, resulting in higher resolution and higher refresh rates. It also was found to be cheaper to manufacture due to lower cost of certain key substrates. Therefore, the Low-Temperature PolySilicon (LTPS) LCD screen helps provide larger pixel densities, lower power consumption that standard LCD and controlled temperature ranges.

The AMOLED display technology is in a completely different league. It doesn’t bother with any liquid mechanism or complex grid structures. The panel uses an array of tiny LEDs placed on TFT modules. These LEDs have an organic construction that directly emits light and minimises its loss by eradicating certain filters. Since LEDs are physically different units, they can be asked to switch on and off as per the requirement of the display to form a picture. This is known as the Active Matrix system. Hence, an Active Matrix Organic Light Emitting Diode (AMOLED) display can produce deeper blacks by switching off individual LED pixels, resulting in high contrast pictures.

The honest answer is that it depends on the requirement of the user. If you want accurate colours from your display while wanting it to retain its vibrancy for a longer period of time, then any of the two LCD screens are the ideal choice. LTPS LCD display can provide higher picture resolution but deteriorates faster than standard IPS LCD display over time.

An AMOLED display will provide high contrast pictures any time but it too has the tendency to deteriorate faster than LCD panels. Therefore, if you are after greater picture quality, choose LTPS LCD or else settle for AMOLED for a vivid contrast picture experience.

AnonD-628531, 06 Aug 2017Surely if you"re not voting for: "Only quality matters" then you"re just shamelessly fanboying???No, because life expectancy is important too. Sony quantum dot displays are supposed to last around 20 000 hours, AMOLEDS may be degrading after just a couple of thousand. A small improvement in black level seems a poor tradeoff for a short product life.

My opinion is as follow: I use Nokia since years, and the hi-end phones all have AMOLED screens. I am used to AMOLED by now and the panels on Nokia phones are of amazing quality. I also have an iPhone 6 with LCD, which is a very good display. Good colors, good saturation en good contrast for an LCD panel. Now which I prefer, that is difficult to say. I believe the iPhone"s display is from Sharp, I am not sure. And it"s a great display. The Nokia Lumia 930 has an amazing display as well and it is a must when using Windows due to the blacks. I like both. At this time I would say it"s a tie in my opinion, but I slighty prefer AMOLED since I"m used to it.

Amoled Is Better......But IPS Display Also Good............ I Have Have Lumia 640 Which Have IPS Display Looks Great Clear Clearity It"s Also Consume Less Power N Black Wallpapers Also Help For Battery....... Amoled Display Best Display Is All Rounder Which I Saw In Samsung Galaxy Series N After That Some Chinese Companies Models Like Lenovo P2........ Anyday I Will Go For Amoled or IPS But TFT Displays No Way :)

Their screen is just slightly worse than LG, but their speakers are better. So no big differences, but the it costs 30% more which isn"t worth it, and the design of it is really unusual and it lays back in an awkward angle, which isn"t for everybody.

I prefer Ips LCD. More comfortable for reading websites and natural colors, more detail, more reliable. I don"t like the background always black color like a black hole, therefore I always set my background with white colors I call it heaven feels, if so oled will comsume more battery.

I wonder how the world which criticised AMOLED screens for highly saturated inaccurate colors now started to love it. That all has been made possible by Samsung only. OnePlus 3T or Nexus 6, for example, have awful displays. Samsung"s SuperAMOLED has been tremendously improved.

NOTE: Just to clear confusion among many of you, AMOLED is not a Samsung Brand or technology. It is a type of screen. Samsung"s variation of AMOLED is SuperAMOLED. P-OLED is a type of screen. It is not a LG Brand. All the votes to AMOLED is because of Samsung though, as AMOLED by others are over saturated, inaccurate and have low brightness, something which Samsung struggled from in initial days (or years?).

regs, 06 Aug 2017That"s just IPS. Yet Sharp"s IPS one is far better.You"re wrong, Sony"s Triluminous displays use Quantum Dot screens (or let"s say "Q-led" as Samsung is naming it), it"s not just a plain IPS LCD.

XtremE16, 06 Aug 2017Amoled display is not show true color and over brightness... Useless display..... Wait for SON... moreSony doesn"t produce displays they buy them from sharp and LG

AnonD-678801, 06 Aug 2017Sony"s Triluminos Display is the best for me... tried AMOLEDs but I Dont like oversaturated co... more"trilominous" is an LCD lol nothing special about it it"s the same one apple uses and calls it retina

I use A7 2016 1 and half year not seeing burn in issue.It wasn"t my screen... since I have been using Sony devices... however my mom"s Samsung had a S4 Mini and its display had burns after 2 years of use, (now she has an S7 Active, lets see how long it last)... my aunt has an S6 and its display burned after just 1 year... and I have seen many others...

It is more noticeable on devices from users that never turn on Screen Rotation and tend to use a lot of one app... in my family"s case Whatsapp, Keyboard and Notification Bar is the culprit.

I understand why people prefer AMOLED, they do look vibrant, with true blacks, and potentially better battery management, however I have no complains with current offerings from Sony, and even less complains from my Surface Book which has one of the best LCD displays I"ve ever seen...

IME the problem with AMOLED lies in their Diamond Pentile matrix. Not to undermine others but I never see AMOLED phones that have screen burn-in. At least on my phone, my dad"s and my mom"s. If Samsung could rearrange the matrix to equal RGB I think the image could"ve look as sharp as LCD at the same screen size and resolution.

But I"ll go with the last option though. As long as the screen has wide viewing angle, deep blacks, great contrast & sunlight legibility, decent PPI & color accuracy, and suitable for night reading then I"m happy. Quality first, tech specs later.

Right now , AMOLED all the way , it colours are way better , or saturated & excellent viewing indoors or outdoors .I have IPS LCD screens with 1500 + viewing angle screen ( Excellent for IPS standard ) , but still AMOLED beats it by miles.

BurnIn or rather Colour Loss issue exists for AMOLED over 2 - 3 years of usage , but who uses mobile over 5 years , by which time battery is reduced or 4g goes to 5g.

Quality Quantum Dot or as said MicoLED is future but is still not mature enough , will need 5 - 7 years of research & improvement to near match OLED standard , till then AMOLED will rule upcoming LG , Iphone , Samsung phones ,

Yes ,Sony IPS LCD Triluminos are the best in LCD , but unfortunately they dropped on new tech like 4 RGBW combination as in Xperia P ( Which had excellent outdoor visibility ) ,still its 4K Triluminos is excellent & if Sony goes for OLED with Triluminos it will kill Samsung OLED for sure. I assume Quantum Dot of Sony Mobile will be best in future.

regs, 06 Aug 2017AMOLEDs have poor viewing angles - significant color shift even on little angles. Haven"t seen... moreAMOLEDs have poor viewing angles? Really? I haven"t used that many phones over the years but I used Nokia E7 for a couple of years when it came out. It had an AMOLED screen with Nokia"s ClearBlack technology and the screen was simply stunning. If I remember correctly there wasn"t practically any color shift when you angled the screen. You could angle the phone so that the screen would be just a tiny sliver and the brightness and the colors would pretty much stay the same.

I remember being gutted after moving to Moto G which has an IPS display. There"s a huge shift in brightness when you angle the screen even a little bit, and this obviously affects the colors as well, although obviously things aren"t as terrible as they are with TN panels. I used a cheap candybar Samsung which had a TN panel (or so I assume) and it was just dreadful. You couldn"t angle the phone at all because the color shift was so huge the colors practically became reversed.

I"ve briefly used Samsungs with AMOLED screens at work and they were totally fine as well, even if I don"t remember them being as gorgeous as Nokia E7"s screen. In any case they were far better than any IPS screen on phones I"ve seen.

It can be argued that the display on your smartphone is its most important feature, as it is the principle way in which you interact with your device. A poor display means a poor user experience. As with all tech, it is easy to spot an under-performer, however the differences between a good display and a truly excellent display are harder to discern.

Roughly speaking there are two main types of displays used in smartphones: LCD and LED. These two base technologies have been refined and tweaked to give us AMOLED and IPS LCD. The former stands for Active Matrix Organic Light-Emitting Diode, while the latter means In-Plane Switching Liquid Crystal Display.

All of this hasn’t gone unnoticed by the marketing people, which means that plain old AMOLED or regular IPS LCD aren’t the terms used in the marketing fluff. Instead, we have Super AMOLED, Dynamic AMOLED, Super LCD, Super Retina OLED, Super Retina XDR, Infinity Display, and so on. But what’s any of that actually mean?

The LED part of AMOLED stands for Light Emitting Diode. It’s the same tech as you find on many home appliances that show that the power is on with a little red light. An LED display takes this concept, shrinks it down, and arranges the LEDs in red, green, and blue clusters to create an individual pixel.

The O in AMOLED stands for organic. It refers to a series of thin organic material films placed between two conductors in each LED. These produce light when a current is applied.

Finally, the AM part in AMOLED stands for Active Matrix, rather than a passive matrix technology. In a passive matrix, a complex grid system is used to control individual pixels, where integrated circuits control a charge sent down each column or row. But this is rather slow and can be imprecise. Active Matrix systems attach a thin film transistor (TFT) and capacitor to each sub-pixel (i.e. red, green, or blue) LED. The upshot is that when a row and column is activated, the capacitor at the pixel can retain its charge in between refresh cycles, allowing for faster and more precise control.

The image above is a close-up shot of the AMOLED display on the Samsung Galaxy S8. The RGB triangular pattern is clearly shown. Towards the bottom of the image, the green and red LEDs are off and the blue LEDs are on only slightly. This is why AMOLED displays have deep blacks and good contrast.

Super AMOLED is a marketing term from Samsung. It means a display that incorporates the capacitive touchscreen right in the display, instead of it being a separate layer on top of the display. This makes the display thinner.

Dynamic AMOLED is another marketing term from Samsung. It denotes Samsung’s next-generation AMOLED display which includes HDR10+ certification. According to Samsung, Dynamic AMOLED also reduces the harmful blue light emitted from the display, which helps reduce eye strain and helps lessen sleep disturbances if you’re using your phone late in the day!

As for Infinity Display (or Infinity-O Display), it is more marketing from Samsung. It means “a near bezel-less, full-frontal, edge-to-edge” display. However, it is still a Super AMOLED unit.

LCD displays work with a backlight that shines through some polarizing filters, a crystal matrix, and some color filters. Liquid crystals untwist when an electric charge is applied to them, which affects the frequency of the light that can pass through. Since the crystals can be twisted to varying degrees depending on the voltage used, a display can be built when they are used with polarized panels. A grid of integrated circuits is then used to control each pixel, by sending a charge down into a specific row or column. Colors are created by the use of red, green, and blue filters, known as sub-pixels, which are then blended by varying degrees to produce different colors.

The above image is of an LCD display from a Huawei Mate 8. Notice how the pixels are made up of equally-sized sub-pixels, one for each of the colors: red, green, and blue.

Pixels can suffer from lower aperture at higher resolutions, as transistor sizes can’t be shrunk further, reducing peak brightness and wasting energy.

Like Super AMOLED, a Super LCD display also incorporates the touchscreen. There is no “air gap” between the outer glass and the display element, which means it has similar benefits to Super AMOLED.

Samsung isn’t the only company that is good at marketing, there is another! Apple has coined the term “Retina” for its displays. The term was first used for its smartphones with the launch of the iPhone 4, as it offered a significantly greater pixel density (over 300 ppi) when compared to the iPhone 3GS. Later came Retina HD, which applies to iPhones with at least a 720p screen resolution.

All Retina and Retina HD displays on the iPhone are LCD IPS displays. However, things have changed a bit with the iPhone X as it features an AMOLED display, now marketed under the term Super Retina. It’s still an AMOLED display. It just has extra adjectives. With the launch of the iPhone 11 Pro, Apple coined the term Super Retina XDR. The XDR part means Extended Dynamic Range, as they have better contrast ratios and higher peak brightness.

Not all Retina displays use OLED. Although the MacBook Pro is marketed with a “Retina” display, as you can see from the magnified image above, it is a regular LCD, even if it uses the latest Apple silicon.

Both technologies can be used to build displays with 720p, 1080p, Quad HD, and 4K resolutions. And OEMs have made handsets that support HDR10 using both LCD and AMOLED displays. So from that point of view, there isn’t much difference between the two.

When it comes to color, we know that the blacks will be deeper and the contrast ratios higher on AMOLED displays. But, overall color accuracy can be high on both types of display.

One of the main weaknesses of AMOLED displays is the possibility of “burn-in”. This is the name given to a problem where a display suffers from permanent discoloration across parts of the panel. This may take the form of a text or image outline, fading of colors, or other noticeable patches or patterns on the display. The display still works as normal, but there’s a noticeable ghost image or discoloration that persists. It occurs as a result of the different life spans between the red, green, and blue LED sub-pixels used in OLED panels.

Blue LEDs have significantly lower luminous efficiency than red or green pixels, which means that they need to be driven at a higher current. Higher currents cause the pixels to degrade faster. Therefore, an OLED display’s color doesn’t degrade evenly, so it will eventually lean towards a red/green tint (unless the blue sub-pixel is made larger, as you can see in the first image in this post). If one part of the panel spends a lot of time displaying a blue or white image, the blue pixels in this area will degrade faster than in other areas.

The theoretical lifespan of an AMOLED display is several years, even when used for 12 hours a day. However, there is anecdotal evidence that some displays suffer from burn-in quicker than others. Displays that show signs of burn-in after only a few months should be considered defective because they certainly aren’t normal.

While owners of devices with LCD screens might congratulate themselves for picking a smartphone that is immune to burn-in, there can be a problem with LCD panels called “image retention.” Put simply, liquid crystals can develop a tendency to stay in one position when left at the same voltage for extended periods. Thankfully this phenomenon is normally temporary and can usually be reversed by allowing the liquid crystals to return to their relaxed state.

Picking a winner can be hard as there are many factors to consider, not only about the display technologies but also about the other components in a handset. For example, if you are an AMOLED fan, then would you consider a device with large storage and a good processor, but with an LCD display? The same argument works the other way for LCD fans. Generally, you’ll be fine with either display type, so just pick the handset you like.

Higher-end devices typically sport AMOLED displays and mid-range/budget devices usually use LCD. But that isn’t set in concrete as there are plenty of high-end devices that have LCD displays. With OLED production costs dropping dramatically in recent years, more and more budget options will be offering OLED panels in the future.

Companies like LG and Samsung have seen this trend coming and are rapidly expanding their OLED (and flexible OLED) production capabilities. LCD might still have a bright future in televisions and other large-panel applications, but for now, it looks like mobile will be increasingly dominated by OLED screens.

What do you think? AMOLED or LCD? What about the terms like Retina vs Infinity Display? Are they meaningful to you? Please let me know in the comments below.

A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display that uses thin-film-transistor technologyactive matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments.

In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET. Paul K. Weimer, also of RCA implemented Wallmark"s ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968. In 1971, Lechner, F. J. Marlowe, E. O. Nester and J. Tults demonstrated a 2-by-18 matrix display driven by a hybrid circuit using the dynamic scattering mode of LCDs.T. Peter Brody, J. A. Asars and G. D. Dixon at Westinghouse Research Laboratories developed a CdSe (cadmium selenide) TFT, which they used to demonstrate the first CdSe thin-film-transistor liquid-crystal display (TFT LCD).active-matrix liquid-crystal display (AM LCD) using CdSe TFTs in 1974, and then Brody coined the term "active matrix" in 1975.high-resolution and high-quality electronic visual display devices use TFT-based active matrix displays.

The liquid crystal displays used in calculators and other devices with similarly simple displays have direct-driven image elements, and therefore a voltage can be easily applied across just one segment of these types of displays without interfering with the other segments. This would be impractical for a large display, because it would have a large number of (color) picture elements (pixels), and thus it would require millions of connections, both top and bottom for each one of the three colors (red, green and blue) of every pixel. To avoid this issue, the pixels are addressed in rows and columns, reducing the connection count from millions down to thousands. The column and row wires attach to transistor switches, one for each pixel. The one-way current passing characteristic of the transistor prevents the charge that is being applied to each pixel from being drained between refreshes to a display"s image. Each pixel is a small capacitor with a layer of insulating liquid crystal sandwiched between transparent conductive ITO layers.

The circuit layout process of a TFT-LCD is very similar to that of semiconductor products. However, rather than fabricating the transistors from silicon, that is formed into a crystalline silicon wafer, they are made from a thin film of amorphous silicon that is deposited on a glass panel. The silicon layer for TFT-LCDs is typically deposited using the PECVD process.

Polycrystalline silicon is sometimes used in displays requiring higher TFT performance. Examples include small high-resolution displays such as those found in projectors or viewfinders. Amorphous silicon-based TFTs are by far the most common, due to their lower production cost, whereas polycrystalline silicon TFTs are more costly and much more difficult to produce.

The twisted nematic display is one of the oldest and frequently cheapest kind of LCD display technologies available. TN displays benefit from fast pixel response times and less smearing than other LCD display technology, but suffer from poor color reproduction and limited viewing angles, especially in the vertical direction. Colors will shift, potentially to the point of completely inverting, when viewed at an angle that is not perpendicular to the display. Modern, high end consumer products have developed methods to overcome the technology"s shortcomings, such as RTC (Response Time Compensation / Overdrive) technologies. Modern TN displays can look significantly better than older TN displays from decades earlier, but overall TN has inferior viewing angles and poor color in comparison to other technology.

Most TN panels can represent colors using only six bits per RGB channel, or 18 bit in total, and are unable to display the 16.7 million color shades (24-bit truecolor) that are available using 24-bit color. Instead, these panels display interpolated 24-bit color using a dithering method that combines adjacent pixels to simulate the desired shade. They can also use a form of temporal dithering called Frame Rate Control (FRC), which cycles between different shades with each new frame to simulate an intermediate shade. Such 18 bit panels with dithering are sometimes advertised as having "16.2 million colors". These color simulation methods are noticeable to many people and highly bothersome to some.gamut (often referred to as a percentage of the NTSC 1953 color gamut) are also due to backlighting technology. It is not uncommon for older displays to range from 10% to 26% of the NTSC color gamut, whereas other kind of displays, utilizing more complicated CCFL or LED phosphor formulations or RGB LED backlights, may extend past 100% of the NTSC color gamut, a difference quite perceivable by the human eye.

The transmittance of a pixel of an LCD panel typically does not change linearly with the applied voltage,sRGB standard for computer monitors requires a specific nonlinear dependence of the amount of emitted light as a function of the RGB value.

In-plane switching was developed by Hitachi Ltd. in 1996 to improve on the poor viewing angle and the poor color reproduction of TN panels at that time.

Initial iterations of IPS technology were characterised by slow response time and a low contrast ratio but later revisions have made marked improvements to these shortcomings. Because of its wide viewing angle and accurate color reproduction (with almost no off-angle color shift), IPS is widely employed in high-end monitors aimed at professional graphic artists, although with the recent fall in price it has been seen in the mainstream market as well. IPS technology was sold to Panasonic by Hitachi.

Most panels also support true 8-bit per channel color. These improvements came at the cost of a higher response time, initially about 50 ms. IPS panels were also extremely expensive.

IPS has since been superseded by S-IPS (Super-IPS, Hitachi Ltd. in 1998), which has all the benefits of IPS technology with the addition of improved pixel refresh timing.

In 2004, Hydis Technologies Co., Ltd licensed its AFFS patent to Japan"s Hitachi Displays. Hitachi is using AFFS to manufacture high end panels in their product line. In 2006, Hydis also licensed its AFFS to Sanyo Epson Imaging Devices Corporation.

It achieved pixel response which was fast for its time, wide viewing angles, and high contrast at the cost of brightness and color reproduction.Response Time Compensation) technologies.

Less expensive PVA panels often use dithering and FRC, whereas super-PVA (S-PVA) panels all use at least 8 bits per color component and do not use color simulation methods.BRAVIA LCD TVs offer 10-bit and xvYCC color support, for example, the Bravia X4500 series. S-PVA also offers fast response times using modern RTC technologies.

When the field is on, the liquid crystal molecules start to tilt towards the center of the sub-pixels because of the electric field; as a result, a continuous pinwheel alignment (CPA) is formed; the azimuthal angle rotates 360 degrees continuously resulting in an excellent viewing angle. The ASV mode is also called CPA mode.

A technology developed by Samsung is Super PLS, which bears similarities to IPS panels, has wider viewing angles, better image quality, increased brightness, and lower production costs. PLS technology debuted in the PC display market with the release of the Samsung S27A850 and S24A850 monitors in September 2011.

TFT dual-transistor pixel or cell technology is a reflective-display technology for use in very-low-power-consumption applications such as electronic shelf labels (ESL), digital watches, or metering. DTP involves adding a secondary transistor gate in the single TFT cell to maintain the display of a pixel during a period of 1s without loss of image or without degrading the TFT transistors over time. By slowing the refresh rate of the standard frequency from 60 Hz to 1 Hz, DTP claims to increase the power efficiency by multiple orders of magnitude.

Due to the very high cost of building TFT factories, there are few major OEM panel vendors for large display panels. The glass panel suppliers are as follows:

External consumer display devices like a TFT LCD feature one or more analog VGA, DVI, HDMI, or DisplayPort interface, with many featuring a selection of these interfaces. Inside external display devices there is a controller board that will convert the video signal using color mapping and image scaling usually employing the discrete cosine transform (DCT) in order to convert any video source like CVBS, VGA, DVI, HDMI, etc. into digital RGB at the native resolution of the display panel. In a laptop the graphics chip will directly produce a signal suitable for connection to the built-in TFT display. A control mechanism for the backlight is usually included on the same controller board.

The low level interface of STN, DSTN, or TFT display panels use either single ended TTL 5 V signal for older displays or TTL 3.3 V for slightly newer displays that transmits the pixel clock, horizontal sync, vertical sync, digital red, digital green, digital blue in parallel. Some models (for example the AT070TN92) also feature input/display enable, horizontal scan direction and vertical scan direction signals.

New and large (>15") TFT displays often use LVDS signaling that transmits the same contents as the parallel interface (Hsync, Vsync, RGB) but will put control and RGB bits into a number of serial transmission lines synchronized to a clock whose rate is equal to the pixel rate. LVDS transmits seven bits per clock per data line, with six bits being data and one bit used to signal if the other six bits need to be inverted in order to maintain DC balance. Low-cost TFT displays often have three data lines and therefore only directly support 18 bits per pixel. Upscale displays have four or five data lines to support 24 bits per pixel (truecolor) or 30 bits per pixel respectively. Panel manufacturers are slowly replacing LVDS with Internal DisplayPort and Embedded DisplayPort, which allow sixfold reduction of the number of differential pairs.

Backlight intensity is usually controlled by varying a few volts DC, or generating a PWM signal, or adjusting a potentiometer or simply fixed. This in turn controls a high-voltage (1.3 kV) DC-AC inverter or a matrix of LEDs. The method to control the intensity of LED is to pulse them with PWM which can be source of harmonic flicker.

The bare display panel will only accept a digital video signal at the resolution determined by the panel pixel matrix designed at manufacture. Some screen panels will ignore the LSB bits of the color information to present a consistent interface (8 bit -> 6 bit/color x3).

With analogue signals like VGA, the display controller also needs to perform a high speed analog to digital conversion. With digital input signals like DVI or HDMI some simple reordering of the bits is needed before feeding it to the rescaler if the input resolution doesn"t match the display panel resolution.

The statements are applicable to Merck KGaA as well as its competitors JNC Corporation (formerly Chisso Corporation) and DIC (formerly Dainippon Ink & Chemicals). All three manufacturers have agreed not to introduce any acutely toxic or mutagenic liquid crystals to the market. They cover more than 90 percent of the global liquid crystal market. The remaining market share of liquid crystals, produced primarily in China, consists of older, patent-free substances from the three leading world producers and have already been tested for toxicity by them. As a result, they can also be considered non-toxic.

आपके स्मार्टफोन की डिस्प्ले के बारे में आप कितना जानते हैं? डिस्प्ले के नाम जैसे कि AMOLED, OLED, LCD, TFT के बारे में आप कितना विस्तार से जानते हैं? इनके नाम बहुत छोटे हैं, लेकिन इनमें से कौन-सा बेहतर है, किस रिफ्रेश रेट के साथ आता है, रेज़ॉल्यूशन कितना है इन सब सवालों को जानकर यदि आप अपने लिए स्मार्टफोन चुनना चाहते हैं तो आपके इन सभी प्रश्नों के उत्तर मिलेंगे यहाँ।

पिछले कुछ सालों में स्मार्टफोन की डिस्प्ले काफी बेहतर हुई हैं। लेकिन प्रत्येक स्मार्टफोन डिस्प्ले के साथ जो शार्ट-फॉर्म एक संक्षिप्त नाम जुड़ता है, जैसे कि AMOLED, LCD, इत्यादि वो केवल नाम नहीं बल्कि अपने आप में एक तकनीक है। स्मार्टफोन पर लगे पैनल AMOLED, OLED, LED, LCD, IPS, TFT, LTPS, इत्यादि होते हैं। ये सभी पूर्णत: अलग होते हैं।

पहले ही इतने टाइप के पैनल मौजूद हैं, ऐसे में स्मार्टफोन निर्माता द्वारा फैंसी नामों का इस्तेमाल जैसे कि Apple द्वारा Super Retina XDR और Samsung द्वारा Dynamic AMOLED ग्राहकों के बीच भ्रम या असमंजस को और बढ़ा देता है।

डिस्प्ले के टाइप तो बहुत सारे हैं जैसे कि TFT, LTPS, AMOLED, OLED, IPS, LCD इत्यादि। लेकिन इन दिनों TFT, LTPS जैसी डिस्प्ले काफी कम हो गयीं हैं। किफ़ायती दामों पर और मिड-रेंज में आने वाले फोनों में आपको IPS LCD डिस्प्ले मिलेगी। लेकिन इन सबका विस्तार से समझें, तो मतलब क्या है ?

अगर संक्षिप्त रूप से और आसान भाषा में समझें तो दो तरह की टेक्नोलॉजी- एलसीडी (LCD) और ओलेड (OLED) बाज़ार में आ रहीं हैं। प्रत्येक में कुछ विभिन्न प्रकार और जनरेशन हैं जो बाकी के स्क्रीन टाइप शार्ट फॉर्म को बनाती हैं। इसी तरह टेलीविज़न की दुनिया में भी अलग स्क्रीन टाइप उपलब्ध हैं जैसे कि LED, QLED, miniLED – ये सब दरसअल एलसीडी (LCD) तकनीक के ही अलग अलग रूप हैं जिनमें थोड़ी विविधताएं हैं।

LCD का मतलब या फुल फॉर्म है लिक्विड क्रिस्टल डिस्प्ले (Liquid Crystal Display)। इसमें लिक्विड क्रिस्टल्स की एक श्रंखला दी जाती है जिसके पीछे एक बैकलाइट होती है। इस डिस्प्ले टाइप का हर जगह आसानी से उपलब्ध होना और कम दामों में इसका निर्माण इसे स्मार्टफोनों के लिए एक प्रचलित विकल्प या पसंद बनाता है।

स्मार्टफोनों में आपको दोनों डिस्प्ले TFT और IPS मिलती हैं। TFT का फुल फॉर्म है – Thin Film Transistor, जो LCD का ही एक बेहतर या एडवांस्ड वर्ज़न है, जो एक एक्टिव मैट्रिक्स (active matrix) का इस्तेमाल करता है। active matrix का अर्थ है कि प्रत्येक पिक्सेल एक अलग ट्रांजिस्टर और कपैसिटर से जुड़ा होता है।

TFT डिस्प्ले का सबसे बड़ा फायदा यही है कि इसके प्रोडक्शन में तुलनात्मक कम खर्च होता है और इसमें असल LCD के मुकाबले ज्यादा कॉन्ट्रास्ट मिलता है। वहीं TFT LCD में नुकसान ये है कि इन्हें रेगुलर LCD प्रकारों के मुकबाले ज्यादा एनर्जी यानि बैटरी चाहिए, इनके व्यूिंग एंगल और रंग भी इतने अच्छे नहीं होते। इन्हीं सब कारणों से बाकी डिस्प्ले विकल्पों की गिरती कीमतों के कारण अब TFT डिस्प्ले का इस्तेमाल स्मार्टफोनों में नहीं किया जाता।

TFT(Thin Film Transistor) – ये भी LCD डिस्प्ले का ही एक प्रकार है जिसमें नीचे एक पतली सेमीकंडक्टर की परत होती है जो हर एक पिक्सल पर रंगों को नियंत्रित करने का काम करता है। इसका और AMOLED में आने वाले AM यानि कि active matrix का काम लगभग एक ही है।

LTPS(Low Temperature PolySilicon) – ये भी Si (amorphous silicon) तकनीक पर आधारित TFT का ही वैरिएंट है जिसमें आपको हाई रेज़ॉल्यूशन मिलता है और ऊर्जा यानि कि पॉवर साधारणत: TFT से कम लेता है।

IGZO(Indium Gallium Zinc Oxide) – ये भी एक सेमिकंडक्टर मैटेरियल है जो डिस्प्ले के नीचे लगी फिल्म में इस्तेमाल होता है और आजकल a semiconductor material used in TFT films, which also allows higher resolutions and lower power consumption, and sees action in different types of LCD screens (TN, IPS, VA) and OLED displays

LTPO( Low Temperature Polycrystaline Oxide) – इस टेक्नोलॉजी को Apple ने डेवेलप किया है और इसे वर्तमान समय में OLED और LCD दोनों तरह की स्क्रीन में इस्तेमाल किया जाता है। इसमें LTPS और IGZO दोनों तकनीकों का इस्तेमाल मिलाकर किया जाता है और नतीजा होता है – डिस्प्ले द्वारा पॉवर का कम इस्तेमाल। ये Apple Watch 4 और Galaxy S21 Ultra में आयी है।

IPS तकनीक को In-Plane Switching तकनीक कहते हैं। IPS टेक्नोलॉजी ने सबसे पहले आयी LCD डिस्प्ले में आने वाली समस्या को दूर किया जिसमें TN तकनीक का इस्तेमाल होता था और इसमें साइड से देखने पर रंग बहुत ख़राब नज़र आते थे। ये कमी ज़्यादातर सस्ते स्मार्टफोन और टैबलेटों में नज़र आया करती थी।

PLS (Plane to Line Switching) – PLS और IPS के नाम या उनके फुल फॉर्म लगभग एक ही जैसे लगते हैं। लेकिन इसमें आश्चर्य की कोई बात नहीं है क्योंकि इनका मुख्य कार्य भी एक समान ही है। PLS टेक्नोलॉजी को Samsung Display द्वारा बनाया गया है और IPS डिस्प्ले की ही तरह इसकी विशेषता भी डिस्प्ले पर अच्छे रंग दर्शाना और बेहतर व्यूइंग एंगल दिखाना ही हैं। लेकिन इसमें OLED और LCD/VA डिस्प्ले के मुकाबले कॉन्ट्रास्ट थोड़ा कम है।

Samsung Display का कहना है कि PLS पैनलों के उत्पादन में लागत कम लगती है, ब्राइटनेस लेवल अच्छा मिलता है और प्रतियोगी कंपनी LG Display के IPS पैनलों के मुकाबले व्यूइंग एंगल भी काफी अच्छे मिलते हैं। अंतत: PLS पैनल का उपयोग किया जाए या IPS पैनल का इस्तेमाल करें, ये पूरी तरह से स्मार्टफोन निर्माताओं पर निर्भर करता है।

AMOLED की फुल फॉर्म – एक्टिव मैट्रिक्स ऑर्गेनिक लाइट एमिटिंग डायोड (Active Matrix Organic Light-Emitting Diode) है। हालांकि ये सुनने में बहुत मुश्किल नाम लग रहा होगा, लेकिन ये है नहीं। हम पहले ही TFT LCD टेक्नोलॉजी में एक्टिव मैट्रिक्स के बारे में पढ़ चुके हैं और अब रहा OLED, तो ये केवल एक पतली फिल्म वाली डिस्प्ले तकनीक है और कुछ नहीं।

और क्योंकि OLED डिस्प्ले में काले पिक्सल बंद हो जाते हैं, उनमें करंट नहीं आता, इसीलिए कॉन्ट्रास्ट लेवल भी LCD डिस्प्ले के मुकाबले ज्यादा मिलता है। AMOLED डिस्प्ले में रिफ्रेश रेट तो ज़्यादा मिल जाता है, लेकिन वहीँ LCD डिस्प्ले को, AMOLED की तुलना में ज्यादा ब्राइट बनाया जा सकता है। क्योंकि ये एक ऑर्
