pantalla tft lcd ips vs super amoled pricelist

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.

Steven Van Slyke and Ching Wan Tang pioneered the organic OLED at Eastman Kodak in 1979. The first OLED product was a display for a car stereo, commercialized by Pioneer in 1997. Kodak’s EasyShare LS633 digital camera, introduced in 2003, was the first consumer electronic product incorporating a full-color OLED display. The first television featuring an OLED display, produced by Sony, entered the market in 2008. Today, Samsung uses OLEDs in all of its smartphones, and LG manufactures large OLED screens for premium TVs. Other companies currently incorporating OLED technology include Apple, Google, Facebook, Motorola, Sony, HP, Panasonic, Konica, Lenovo, Huawei, BOE, Philips and Osram. The OLED display market is expected to grow to $57 billion in 2026.

AMOLED (Active Matrix Organic Light Emitting Diode) is a type of OLED display device technology. OLED is a type of display technology in which organic material compounds form the electroluminescent material, and active matrix is the technology behind the addressing of individual pixels.

An AMOLED display consists of an active matrix of OLED pixels generating light (luminescence) upon electrical activation that have been deposited or integrated onto a thin-film transistor (TFT) array, which functions as a series of switches to control the current flowing to each individual pixel.

Typically, this continuous current flow is controlled by at least two TFTs at each pixel (to trigger the luminescence), with one TFT to start and stop the charging of a storage capacitor and the second to provide a voltage source at the level needed to create a constant current to the pixel, thereby eliminating the need for the very high currents required for PMOLED.

TFT backplane technology is crucial in the fabrication of AMOLED displays. In AMOLEDs, the two primary TFT backplane technologies, polycrystalline silicon (poly-Si) and amorphous silicon (a-Si), are currently used offering the potential for directly fabricating the active-matrix backplanes at low temperatures (below 150 °C) onto flexible plastic substrates for producing flexible AMOLED displays. Brightness of AMOLED is determined by the strength of the electron current. The colors are controlled by the red, green and blue light emitting diodes.  It is easier to understand by thinking of each pixel is independently colored, mini-LED.

IPS technology is like an improvement on the traditional TFT LCD display module in the sense that it has the same basic structure, but with more enhanced features and more widespread usability compared with the older generation of TN type TFT screen (normally used for low-cost computer monitors). Actually, it is called super TFT.  IPS LCD display consists of the following high-end features. It has much wider viewing angles, more consistent, better color in all viewing directions, it has higher contrast, faster response time. But IPS screens are not perfect as their higher manufacturing cost compared with TN TFT LCD.

Utilizing an electrical charge that causes the liquid crystal material to change their molecular structure allowing various wavelengths of backlight to “pass-through”. The active matrix of the TFT display is in constant flux and changes or refreshes rapidly depending upon the incoming signal from the control device.

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.

Display technologies are advancing every day. All the major tech giants like Apple, Samsung, One Plus use one among these technologies for building the displays of their Apple phones or Galaxy Notes. Each has its advantages and disadvantages. So which one is better? Is it the AMOLED favored mostly by Samsung? Or is it the IPS LCD favored by Apple for their iPhones? Let us take a detailed look at the features of AMOLED vs IPS display technologies.

AMOLED stands for Active-Matrix Organic Light-Emitting Diode is a type of display used mainly in mobile phones. You might have seen the AMOLED display mentioned in the specifications for smart devices, especially mobile phones. They are also used in smartwatches, laptops, and even televisions. Let’s see what the terms in AMOLED mean.

The Active Matrix technology came about as an improvement on the existing passive matrix technology that used passive components like wires which were arranged vertically and horizontally to control each pixel. The color and brightness of the pixels and thereby the picture can be altered by varying the electrical charge at the given joint of vertical and horizontal wires. The newer Active Matrix uses active electrical components like transistors and capacitors to carry out the same purpose. Instead of varying current at the intersection of wires to control the pixels, this latest technology uses a grid or matrix of thin-film transistors commonly referred to as TFTs and capacitors.

You might be familiar with the giant LED bulbs used at parties or even as indicators on televisions showing the on/off state. These same LED lights are used in AMOLEDs, but of course in the smallest size possible. The LEDs used are in the primary shades namely Red, Blue, and Green, and are grouped in triangle-shaped pixelated forms.

Compared to the LCD and LED displays, the diodes in the OLED display produce light individually meaning they do not need a backlight like their predecessors. OLEDs use lesser electricity and are thinner compared to LEDs. They are also bendable and may even be curved. However, they are much more expensive than LED displays. Hence in the earlier days, it was majorly used for displays for

Now the technologies mentioned above combine to give the AMOLED displays. Here an OLED display is driven with an active matrix control scheme. The TFTs (thin-film transistors) turn on/off each pixel one at a time. The other scheme where the OLEDs are controlled by a passive matrix requires each grid ( rows and lines) to be controlled together. The advanced AMOLED displays allow for higher resolution display with a much bigger physical size.

AMOLEDs have deep black lights. The blacks are darker than LEDs and LCDs because parts of the screen can be switched off altogether. AMOLEDs are also thinner and lighter than LCDs. This feature especially stands out in a dark theater room where OLED displays give a higher contrast ratio compared to LCDs making for an excellent visual experience. This feature of OLED which can work with no backlight makes it better than LCDs whether or not they have an LED backlight.

Since they use Active Matrix technology over the passive matrix version, AMOLEDs have a faster response time. They are up to a millisecond faster and extract less power from your mobile phone’s battery. Extended battery life means major advantages in the portability department. This adding to its high display features leads to them being extensively used. They are preferred over the other versions by major companies like Samsung. Speaking of power, the amount consumed by an OLED display varies according to the brightness and color of the picture displayed.

AMOLEDs have impressive contrast ratios. The contrast ratio is the ratio of the luminance of white color to the black color of a display unit. The high contrast of AMOLEDs is because when the LEDs are off, it gives complete black and since no backlight is used in LEDs, we get deep blacks.

One of the disadvantages the AMOLED had over LCD was the blurriness caused in sunlight which is a result of its lowered peak-brightness values. This issue was corrected in the advanced Super AMOLEDs. In the Super AMOLEDs, the size of gaps between the various layers of the screen namely the cathode layer, anode layer, organic active layer, TFT layer is made narrower than before.

Another problem associated with the AMOLEDs is that the organic materials used in the emissive layer and the conductive layer suffer degradation. This happens comparatively in a short amount of time. As a result, various display problems arise including image persistence, burn-in, etc which are essentially screen burn type problems and color shifts where some colors fade quicker than others. Burn-in is essentially the pixel quality becoming trash after a while because of the degradation of the organic molecules.

Most flagship models of major companies like Samsung, Apple, and One Plus use either super AMOLED or IPS panel premium LCDs. So what exactly is an IPS display? and how does it feature against like the likes of super AMOLEDs?

First, let us understand the basics of a standard LCD. Simply put, when you apply current to some crystals, they may or may not let through the light which comes from a backlight that covers the whole display. In addition to this, there are polarization and color filters present in LCDs which finally give the primary colors Red, Blue, and Green.

Before we get into detailed explanations, you have to keep in mind that for the final end-product that ends up on the market, the quality of the display does not solely depend on whether it is IPS or AMOLED. The companies usually put their tweaks on top of the existing technology before making them available in the market. AMOLEDs are a newer technology than IPS LCD and improve on it in some areas while still lagging in others.

The IPS LCD stands for In-Plane Switching Liquid Crystal Displays. It emerged onto the scene as an improvement on the existing and vulnerable Thin Film Transistor LCD technology commonly referred to as the TFT. Samsung was the leading manufacturer to employ Super AMOLEDs. The IPS display is mainly being used in Apple iPhones. Apple beginning with the iPhone X is switching to AMOLED displays with contrast ratios of 1000000 to 1

As said before, an IPS display is an improved version of the regular TFT LCDs. Here, the difference comes in the way the anode and the cathode are arranged. They are planted as strip electrodes on one of the two glass substrates.

The IPS display scores big time when it comes to offering better viewing angles compared to the other LCD technologies like Twisted Nematic LCD (TN) and Vertical Alignment LCD (VA). The IPS display can be viewed without any color degradation or blurriness at flimsy shallow angles compared to TN and VA displays.

The consistency of colors and clarity of pictures at wider viewing angles is the major advantage of an LCD. IPS displays have higher resolution. They also can display a wide range of colors. These features also make the IPS displays costlier than TN and VA LCDs. Normally IPS monitors allow up to 178 degrees of viewing angles. These displays almost guarantee absolute color accuracy.

For other LCD models, the color and the brightness of an image vary when viewed from different angles. Compared with them, IPS displays are more suited for someone working as a visual/graphic artist. As a regular television, all LCD models are mostly considered equally good. This is because the viewers would mostly be sitting right in front of the screen where these differences between the models do not matter.

IPS displays are capable of displaying a wider spectrum of colors. Considering no monitors can display the entire color spectrum visible to the human eye, IPS LCD panels are the closest things to a perfect display monitor far better than TN and VA LCDs

Image retention is a problem often associated with LCDs. This happens because of the crystal which gets into a particular position for the light to go through stays in that same spot without falling back into its original position. This leads to some parts of the image being left on the screen. This is, however, a temporary problem. The crystal will eventually twist back into the position when the current is applied to it again. When it comes to color accuracy, the previous generation of LCDs was no match for the AMOLED. They had the highest color accuracy among mobile phones. But recent versions of the LCDs have fared much better versus their counterparts.

Large-sized IPS monitors are not affordable for the average customer. They should be avoided since they offer nothing impressive over other LCDs considering the price range. However, if you are a visual artist or a photographer, IPS displays provide the best color accuracy in the market. It would be more beneficial to you compared to an ordinary TN display unit.

AMOLEDs and IPS LCDs are two sides of the same coin in a sense. They both got their advantages and disadvantages. Their disadvantages are mostly overshadowed by the many tweaks installed by the parent companies to ensure customer satisfaction. From high power consumption to ugly blacks, the flaws are minimized in every newer version.

Cutting edge display technology has been a central feature of flagship smartphones in recent years. The LG V30 arrived late last year with yet another innovation in screen tech: new panel type called P-OLED. With Samsung still marketing its Super AMOLED and Infinity Display technology, and some other manufacturers moving away from the tried and tested IPS LCD, there’s never been more choice for display panel tech in the smartphone market.

P-OLED isn’t exactly the new kid on the block, but the technology is just starting to appear in a number of flagship handsets. We’ve already seen how LG Display’s P-OLED stacks up against Samsung’s AMOLED,but what about the common IPS LCD display technology? That’s what we aim to find out in this P-OLED vs IPS LCD breakdown.

The common LCD stands for Liquid Crystal Display, while IPS stands for “in-plane switching”. The latter controlls the crystal elements in the display’s RGB sub-pixel layout. IPS replaced twisted nematic field effect (TN) as the technology of choice for LCD in the 90s, and is what you’ll find in all LCD-based smartphone panels.

The technology features a polarized backlight passing through the liquid crystals, in front of red, green, and blue color filters for each sub-pixel. With IPS, a current is used to create an electric field parallel to the plate, which twists the polarized crystal and further shifts the polarity of the light. A second polarizer then filters out the light based on its polarity. The more light passes through the second polarizer, the brighter the associated RGB sub-pixel will be.

Each sub-pixel is connected up to a thin-film transistor active matrix, which drives the panel’s brightness and color without consuming as much current as an outdated passive matrix display. Using different TFT materials and production techniques can alter the driving properties of the display and alter the transistor sizes, which affects properties such as brightness, viewing angles, and color gamut. Hence why you’ll find a variety of different naming schemes for IPS LCD display, including Super IPS, Super LCD5, and others.

The makeup of the backlight can vary between LCD panels too, as the white light has to be created from another group of colors. The light source can be made up of LEDs or an electroluminescent panel (ELP), among others, each of which can offer a slightly different white tint and varying degrees of even light across their surface.

OLED technology has been the major rival to LCD in the smartphone market for what seems like forever. Samsung’s AMOLED technology has powered generations of the top selling Android flagship. Plastic-OLED (or P-OLED) is simply the latest iteration of this technology, primarily designed to enable new and interesting form factors.

Compared with the numerous layers of an LCD display, P-OLED is considerably less complicated looking. The key component is a Light Emitting Diode (LED). So rather than relying on a universal backlight, each sub-pixel is capable of producing its own red, green, or blue light, or being shut-off completely. The O part in OLED stands for organic, which is the compound type that lights up when current is applied.

To drive this current, the TFT matrix is used in a very similar way to LCD. Although this time the current is used to produce the light rather than twist the polarizing crystals. As this is an active matrix TFT, Samsung chose to call its OLED panels AMOLED. P-OLED shouldn’t be confused with the outdated PMOLED technology, which stands for passive matrix and isn’t used in any modern pieces of high-end display tech.

So where does the plastic element come in? Well it’s simply the material used as the back substrate on which the TFT and OLED components are placed. Historically, this has been made from glass but using a plastic substrate makes the display more malleable and flexible. It’s important to note however, that switching over to a plastic substrate requires new materials for the TFT plane that can withstand the manufacturing temperatures, while still providing sufficient electron mobility and current for the LEDs.

The two display technologies have their own pros and cons in terms of viewing quality, but plastic OLED has a trick up its sleeve that LCD can’t yet match — flexibility.

Although the very top of a smartphone display will likely feature a protective glass layer, such as Gorilla Glass, the underlying plastic substrate layer does offer some additional shock absorption. This means that it’s less likely that the TFT layer will break on dropping, helping to preserve functionality even if the top layer cracks.

It’s worth stating that flexible LCD alternatives are in development. Japan Display showcased its low-cost flexible LCD technology in early 2017 and other companies are working on Organic LCD and similar ideas. However, the trick is still to match flexible OLED for pixel density and resolution, color gamut, and production yield. So it’s likely to be a while before we see competing flexible LCD products.

Unfortunately, there’s no definitive superior technology between IPS LCD and P-OLED. There are too many variables beyond the basic display type that determine the quality of the viewing experience. These include sub-pixel layouts and manufacturing materials.

No two IPS LCD manufacturers are necessarily alike, and even P-OLED will undoubtedly go through generational revisions over the next few years and continue to improve performance. Furthermore, new advances in LCD technology, including Quantum Dot, WRGB, and others, keep  reinvigorating the already well-refined technology.

AMOLED displays are popular for the pure blacks and energy efficient "glance" displays they enable. Thus they are seen as a premium option for smartphone and laptop users, and AMOLED panels are only seen in really high-end TVs. However, thanks to competition and demand spurring greater production, prices are starting to become more competitive with TFT LCD panels, reports IT industry journal DigiTimes.

According to the source report "The production cost for a 5.5-inch HD AMOLED panel has drifted to US$12.10 recently, compared to US$12.20 for a 5.5-inch HP LTPS LCD panel". This is a big change to the previous state of affairs where AMOLED panels had "much higher,"prices due to the increased production costs. Thanks to the levelling off of prices and demand it"s expected that AMOLED panels will be equipped on up to 50 per cent of smartphones by 2020.

In other recent AMOLED smartphone news, the Nikkei Asian Review asserts that Apple will "use OLED screens in all new iPhones launching in 2018". Industry sources say Apple is considering launching three smartphones in 2018 and all will come equipped with this type of display.

Later this year Apple will launch its first OLED iPhone - but only the premium version will get this type of display, in a design that eschews its iconic Home button. Two other iPhone models released this year will use TFT LCDs.

Back to the AMOLED panel pricing news, and there is hope that larger displays, not just those aimed at smartphones and tablets, will come down in price. LG Display"s E4-2 fab, its second production line for AMOLED displays for TVs, will enter volume production in H2 2017, says DigiTimes. Thanks to the new production line AMOLED TV display production is set to more than double to 1.5 million units, say sources. Furthermore, several Chinese panel makers have been investing in AMOLED production facilities with output set to increase fivefold (comparing 2016 output to that estimated to come on line in 2018).

By now you know that (one of) AMOLED"s Achilles" heel is readability in direct sunlight. But Samsung"s been working hard to fix that with its new Super AMOLED technology. Techblog took the display to task by pitting the Samsung Galaxy S (4-inch, 480 x 800 pixel Super AMOLED) against the HTC Desire (3.7-inch 480 x 800 pixel AMOLED) and Sony Ericsson XPERIA X10 (4-inch, 480 x 854 pixel TFT LCD). It"s clear from the video embedded after the break that the LCD still has the edge in the harsh Greek sun, but the Super AMOLED certainly makes a much stronger showing than its AMOLED sib. In fact, differences in visibility between the LCD and Super AMOLED are often indistinguishable, like the picture above. That"ll be good news for us just as soon as Samsung can start meeting demand... regardless of what Stevie J has to say. Check the video after the break and be sure to click the source for some more side-by-side pics, including a few taken indoors where that Super AMOLED display really shines.
