tft lcd ips vs gorilla glass free sample

IPS-LCDs are costlier than normal TFT LCD and hence are found only on higher end smartphones. A higher resolution (640 x 960 pixels) version of IPS LCD is used in Apple iPhone 4 and is called Retina Display because of its brilliant picture quality.

It is a special alkali-aluminosilicate glass shield with exceptional damage resistance that helps protect mobile displays from scratches, drops, and bumps of everyday use. Many companies like Motorola, Samsung and Nokia are now using Gorilla Glass to make their mobile displays more durable and reliable. It is always better to go for a smartphone with Gorilla Glass for that added protection and peace of mind.

LCDs use a simple grid to supply the charge to a particular pixel on the display. Creating the grid is quite a process! It starts with two glass layers called substrates.

If you want to buy a new monitor, you might wonder what kind of display technologies I should choose. In today’s market, there are two main types of computer monitors: TFT LCD monitors & IPS monitors.

The word TFT means Thin Film Transistor. It is the technology that is used in LCD displays.  We have additional resources if you would like to learn more about what is a TFT Display. This type of LCDs is also categorically referred to as an active-matrix LCD.

These LCDs can hold back some pixels while using other pixels so the LCD screen will be using a very minimum amount of energy to function (to modify the liquid crystal molecules between two electrodes). TFT LCDs have capacitors and transistors. These two elements play a key part in ensuring that the TFT display monitor functions by using a very small amount of energy while still generating vibrant, consistent images.

Industry nomenclature: TFT LCD panels or TFT screens can also be referred to as TN (Twisted Nematic) Type TFT displays or TN panels, or TN screen technology.

IPS (in-plane-switching) technology is like an improvement on the traditional TFT LCD display module in the sense that it has the same basic structure, but has more enhanced features and more widespread usability.

These LCD screens offer vibrant color, high contrast, and clear images at wide viewing angles. At a premium price. This technology is often used in high definition screens such as in gaming or entertainment.

Both TFT display and IPS display are active-matrix displays, neither can’t emit light on their own like OLED displays and have to be used with a back-light of white bright light to generate the picture. Newer panels utilize LED backlight (light-emitting diodes) to generate their light hence utilizing less power and requiring less depth by design. Neither TFT display nor IPS display can produce color, there is a layer of RGB (red, green, blue) color filter in each LCD pixels to produce the color consumers see. If you use a magnifier to inspect your monitor, you will see RGB color in each pixel. With an on/off switch and different level of brightness RGB, we can get many colors.

Winner. IPS TFT screens have around 0.3 milliseconds response time while TN TFT screens responds around 10 milliseconds which makes the latter unsuitable for gaming

Winner. the images that IPS displays create are much more pristine and original than that of the TFT screen. IPS displays do this by making the pixels function in a parallel way. Because of such placing, the pixels can reflect light in a better way, and because of that, you get a better image within the display.

As the display screen made with IPS technology is mostly wide-set, it ensures that the aspect ratio of the screen would be wider. This ensures better visibility and a more realistic viewing experience with a stable effect.

Winner. While the TFT LCD has around 15% more power consumption vs IPS LCD, IPS has a lower transmittance which forces IPS displays to consume more power via backlights. TFT LCD helps battery life.

Normally, high-end products, such as Apple Mac computer monitors and Samsung mobile phones, generally use IPS panels. Some high-end TV and mobile phones even use AMOLED (Active Matrix Organic Light Emitting Diodes) displays. This cutting edge technology provides even better color reproduction, clear image quality, better color gamut, less power consumption when compared to LCD technology.

This kind of touch technology was first introduced by Steve Jobs in the first-generation iPhone. Of course, a TFT LCD display can always meet the basic needs at the most efficient price. An IPS display can make your monitor standing out.

TFT (Thin Film Transistor) LCD (Liquid Crystal Display) dominates the world flat panel display market now. Thanks for its low cost, sharp colors, acceptable view angles, low power consumption, manufacturing friendly design, slim physical structure etc., it has driven CRT(Cathode-Ray Tube) VFD ( Vacuum Fluorescent Display) out of market, squeezed LED (Light Emitting Diode) displays only to large size display area. TFT LCD displays find wide applications in TV, computer monitors, medical, appliance, automotive, kiosk, POS terminals, low end mobile phones, marine, aerospace, industrial meters, smart homes, handheld devices, video game systems, projectors, consumer electronic products, advertisement etc. For more information about TFT displays, please visit our knowledge base.

There a lot of considerations for how to choose a most suitable TFT LCD display module for your application. Please find the check list below to see if you can find a right fit.

Resolution will decide the clearance. Nobody likes to see a display showing pixel clearly. That is the reason for better resolution, going from QVGA, VGA to HD, FHD, 4K, 8K. But higher resolution means higher cost, power consumption, memory size, data transfer speed etc. Orient Display offers low resolution of 128×128 to HD, FHD, we are working on providing 4K for our customers. For full list of resolution available, please see Introduction: LCD Resolution

TFT screen brightness selection is very important. You don’t want to be frustrated by LCD image washout under bright light or you drain the battery too fast by selecting a super brightness LCD but will be used indoor only. There are general guidance listed in the table below.

Orient Display offers standard brightness, medium brightness , high brightness, and high end sunlight readable IPS TFT LCD display products for our customers to choose from.

If the budget is tight, TN type TFT LCD can be chosen but there is viewing angle selection of either 6 o’clock or 12 o’clock. Gray scale inversion needs to be taken of carefully. If a high-end product is designed, you can pay premium to select IPS TFT LCD which doesn’t have the viewing angle issue.

It is similar to viewing angle selection, TN type TFT LCD has lower contrast but lower cost, while IPS TFT LCD has much high contrast but normally with higher cost. Orient Display provides both selections.

Normal TFT LCD displays provide wide enoughtemperature range for most of the applications. -20 to 70oC. But there are some (always) outdoor applications like -30 to 80oC or even wider, special liquid crystal fluid has to be used. Heater is needed for operating temperature requirement of -40oC. Normally, storage temperature is not an issue, many of Orient Display standard TFT display can handle -40 to 85oC, if you have any questions, feel free to contact our engineers for details.

Power consideration can be critical in some hand-held devices. For a TFT LCD display module, backlight normally consumes more power than other part of the display. Dimming or totally shutdown backlight technology has to be used when not in use. For some extreme power sensitive application, sleep mode or even using memory on controller consideration has to be in design. Feel free to contact our engineers for details.

High Level Interfaces: Orient Display has technologies to make more advanced interfaces which are more convenient to non-display engineers, such as RS232, RS485, USB, VGA, HDMI etc. more information can be found in our serious products. TFT modules, Arduino TFT display, Raspberry Pi TFT display, Control Board.

Considering different strength requirements, Orient Display can provide low cost chemical tampered soda-lime glass, Asahi (AGC) Dragontrail glass and Corning high end Gorilla glass. With different thickness requirement, Orient Display can provide the thinnest 0.5mm OGS touch panel, to thickness more than 10mm tempered glass to prevent vandalizing, or different kinds of plastic touch panel to provide glass piece free (fear) or flexible substrates need.

If you can’t find a very suitable TFT LCD Display in our product line, don’t be discouraged. The products listed on our website is only small part of standard products. We have thousands of standard products in our database, feel free to contact our engineers for details.

If you like to have a special display, Orient Display is always flexible to do partial custom solution. For example, to modify the FPC to different length or shape, or use as fewer pinouts as possible, or design an ultra-bright LCD display, or a cover lens with your company logo on it, or design an extreme low power or low cost TFT display etc. our engineers will help you to achieve the goals. The NER cost can start from hundreds of dollars to Thousands. In rare case, it can be tens of thousands of dollars.

A fully custom TFT LCD panel can have very high NRE cost. Depending on the size of the display, quantity and which generation production line to be used. The tooling cost can start from $100,000 to over $1M.

Before we dive in, it"s helpful to understand the layout of a smartphone screen. The oversimplified version is that displays are composed of several layers of material, starting backing material and including a lighting element (like the backlight for LCD screens), which is then topped with a TFT (thin-film transistor) layer, which uses voltage-sipping transistors to keep the display"s pixels shining until you refresh or change the image.

There"s also the touch-sensitive panel; various films and filters that might reduce glare, for instance; and the cover glass, which is often bonded to the touch layer like Gorilla Glass. And there are also sensitive digitizer screens found on Samsung Note family..... ..... enough

The LCD screens are the most common technology used on mobile phones and they range from the budget smartphones like the HTC desire C to high-end tablets, like the Google Nexus 7. Two types of LCDs are primarily found in mobile phones: TFT and IPS technology.

TFT-LCD stands for thin-film transistor - liquid crystal display and use the thin-film transistor technology to improve image quality. They are often just referred to as LCD, since TFT-based LCD screens are the only type used in practice. Each pixel on a TFT-LCD has its own transistor on the glass itself, which offers more control over the images and colors that it renders.

While TFT-LCDs can deliver sharp images, they also tend to offer relatively poor viewing angles. TFT are found on more low-end smartphones or feature phones, and on basic cell phones.

IPS stands for in-plane switching. It involves arranging and switching the molecules of the liquid crystal (LC) layer between the glass substrates. This is done in a plane parallel to these glass plates. It features two transistors for each pixel, where TFT use just one. Requires a more powerful back-light (up to 15% comparing to TFT screens) but resolves the TFT"s weaknesses related to relatively high response time (lower is better), strong viewing angle dependence and low-quality color reproduction.

IPS are more expensive in production and typically are found on high-end mobile phones and portable devices. Apple"s iPhone, iPad, HTC One X and Nokia 920 are a good example of high quality IPS-LCDs screens.

The liquid crystals do no emit light themselves, so LCDs require a backlight. That means that LCD requires more power, and could potentially be more taxing on your phone’s battery.

The LCDs however produce some of the most realistic colors you can find on a screen, but might not offer as wide of a contrast ratio (darker darks and brighter brights) as AMOLED or OLED.

Due to this simple construction, AMOLED offers many advantages over LCD displays as it is thinner, brighter, more power efficient and provides wider viewing angles. They also provide much better contrast and response times.

Mostly those advantages are down to the fact that AMOLED technology doesn"t require a back-light. The black colour stays truly black without producing an energy (unlike on many LCDs where the black is rather grey and its being artificially made), which also leads to expanding battery life as long as the background of your phone is close to black.

However AMOLED screens have proved costly and difficult to produce in the same numbers as LCD, a fact that forced HTC company to replace AMOLED screen in their HTC Desire for Super-LCD halfway through its manufacturing life. A decision that led HTC to stick with LCD screens onward. Often those screens were also criticized to have lower visibility in the direct light than their LCDs counterparts and having over-saturated colours, until Samsung introduced the next generation of Super AMOLED technology, which solved the above issues.

LCD screens start with an always-on backlight; this technology requires light to create black, white, and colors. High-end LCDs produce the most accurate colors, though their manufacturers sometimes intentionally calibrate LCDs to produce weaker red, blue, and purple shades in order to reduce the device"s power consumption.

AMOLEDs also age more rapidly than LCD"s. Using an organic polymers, means that the red and blue colors deteriorate faster than green. Samsung used Super AMOLED plus screens in their Galaxy S II phones, but reverted back to Super AMOLED screens for the Galaxy S III citing screen life as the reason for the switch.

Both display technologies offer advantages and disadvantages. AMOLED screens have higher contrasts and deeper, true blacks, but LCD’s tend to offer more accurate colors. While AMOLED displays are brighter when viewed off-center, LCD panels can be viewed more easily under direct sunlight.

AMOLED displays tend to be more power efficient overall however, LCD panels are more power efficient when it comes to displaying web pages. AMOLED screens have better viewing angles, but LCD panels tend to be sharper on lower resolution panels thanks to the use of the RGB structure instead of PenTile/RGBG.

One of the problems with existing LCD displays used on smartphones is that they can’t keep up. While the internal hardware and operating system are fast enough to deliver a full 60 frames-per-second (FPS), the screens themselves lag behind, leading to pixelated video and ghost images appearing as your screen moves.

PureMotion HD+ uses an IPS type LCD display that is also given a higher voltage difference when changing states to produce a clean transition from frame to frame, even when operating at top speeds. This allows the display to deliver a steady 60FPS without any blurring. Nokia claims it lights up twice as fast on 920 than on any competing LCDs smartphones.

Ever take your phone outside and squint to read the screen? Phones with high reflectance can be a real setback, but some manufacturers are good at getting on top of it. ClearBlack is Nokia"s name for an anti-glare filters applied to the screen above the touch layer (but below the glass) on its high-end phones. It works on both AMOLED and LCD screens.

The color saturation is beyond the reach of any LCD out there, which make even the dullest image appear remarkably vibrant. Still, if you are not a fan of the oversaturated look of AMOLEDs, Samsung gives you the option to tune down the saturation to more natural levels and enjoy the best of both worlds. There"s a dedicated Adobe RGB setting that gets this done.

Triluminos is a technology that enables LCD TFT displays to show a wider range of colors, therefore the images are richer and more vivid. It’s all down to intelligent backlight technology, a Triluminos display reproduces more tones and textures than standard LED backlighting. Sony says that it boasts a color gamut that is 50 percent larger than that of a conventional LCD panel.

Conventional LCD displays use a white backlight that passes through red, blue, and green filters to form the color that the user perceives. The problem with this approach is that filters are not very selective – in other words, it’s hard to form very specific colors, and the end result might be a washed out colors (LCD needs very careful calibration to work perfectly). With Triluminos, the white backlight is replaced by a blue LED, which emits a blue light that causes a film of quantum dots to produce pure green and pure red. The different wavelength light is combined to form the color on the screen. This way the display can show more pure, unadulterated colors.

Sony has been using the X-Reality and X-Reality Pro image processors on its high-end TVs for a while now, though it’s not clear if X-Reality for mobile is the same thing.

According to Sony,Triluminos and X-Realityshould allow the Sony screens to compete with the Super AMOLED displays on Samsung flagships, which are recognized for their rich colors. But that’s the theory. In practice Xperia"s Z1 screen is a huge improvement in image quality since the Xperia Z and the images are truly coming to live (also the viewing angles has been greatly improved) but still cannot compete fully not only with super AMOLED screens, but also with the top IPS LCD panels.

Saying that this technology is superior to conventional LCD"s, and most likely will become dominant in the next couple of years. The very first example of implementing it into LCD IPS screen is a new Amazon Kindle Fire HDX 8.9, that surpasses every panel on the market related to intensity and accuracy of the colours produced. Here are some of the key findings from DisplayMate"s regarding Nexus 7 vs Fire HDX vs new iPad Mini display shootout

When Apple rolled out the iPhone 5, they announced that it had a full sRGB gamut, and would be a substantial improvement over the 4 and 4S displays. They also had done away with layers of technology below the screen to bring the display as close to the glass as possible, something they said would bring increased brightness and sharpness to the user"s eye. In practice however, compering the quality and brightness, Iphone 4S has still upper hand.

Retina Display - Apple"s proprietary name for its LCD screen, which serves up a 1,136x640 pixel resolution in mobile phones.1080p - The highest common high-definition screen resolution, measuring 1,920 pixels by 1,080 pixels. Also called "full HD."

720p -The lower high-definition designation, 1,280 by 720 pixels.Super LCD - Manufactured by Samsung, but used mostly by HTC, Super LCD is a display technology which removes the air gap between the outer glass and the display elements. This reduces the glare, and also consumes less power and has better outdoor visibility than regular LCD screens.

IPS - A type of LCD screen technology known for producing clearer image quality and wider viewing angles, among other traits. It"s used in many smartphones.

Welcome at Riverdi University. In this lecture we’ll talk about different kinds of glass in TFT LCD displays and surfaces that we use to protect displays, or we can use to protect with the glass the entire devices

We will talk about different types of glass in TFT LCD displays, then the surface treatments, what we do to achieve different parameters of glass surfaces, about the hardness – important when we want to protect something, then about painting the glass, how we do it and what we can achieve, IK rate, how much mechanical impact we can place on the glass, and will it withstand this still and at the end about laminated glass, why we laminate glass and what we can achieve by doing that.

The most important thing with the glass in TFT LCD displays is to protect the display, but not only. As you can see on the pictures above, glass is an element of the design of the devices. It makes devices look better and can be designed in a way that protects not only the display, but the entire surface of a device, like for example for the coffee machine on the picture above, where we have a display with some additional graphic that covers the whole front of the device. Glass is one of the best materials that we use in electronics to protect screens, because it is very hard and it is hard to scratch. It is mechanically strong, cheap, and exceptionally good in optics. For glass, the transparency rate is typically more than 90% or even 95% percent. It is widely available, we know a lot of techniques how to manufacture it and how to prepare it for some special advanced designs as we can change the shape of glass quite easily nowadays.

Now we will talk about types of glass that we use to protect screens and devices. Mainly we use two types of glass in TFT LCD displays, one is chemically strengthened glass, that we call CS type glass, the other is thermally tempered glass, hardened glass where we use hot temperature to make it stronger. For our standard products we typically use on the touch screens chemically strengthened glass. Our standard thickness is 1.1-millimeter thickness. This kind of glass is pretty strong, comparing to the regular glass. Chemical strengthening means that we treat the surface with ions, usually silver ions. We increase the strength of the surface of the glass because glass usually breaks when the surface breaks. We do not change the glass internally with chemical strengthening, we just change the surface hardness, and it is enough to make the glass much stronger.

As you can see in the table above, with chemical strengthening we can make glass even 6 or 8 times mechanically stronger than the regular one. This is a very long process; it can take several hours, and we need hot temperature, 400 or more degrees. Thermally tempered glass is a separate way of strengthening glass. We use hot temperature and very fast cooling to make the glass stronger. We need a higher temperature, 700 degrees in this process, but it is much faster, it takes just several minutes, and we achieve strong glass, 4 to 5 times stronger than regular float glass. Thermally tempered glass is not as strong as chemically strengthened glass. It is cheaper, but we cannot use it for thin glass. The thinnest glass that we can thermally temper is 3-4 millimeter. If the glass is thinner, with hot temperature it starts floating and the surface will not be flat again. So, if we have a thick glass, it would be cheaper to use the thermally tempered solution. That is why it is more popular. For thinner glass we use chemical strengthening, because we cannot use the thermally tempered solution.

Now we will talk about the other difference between these two methods of strengthening glass. On the left side of the picture above, you can see chemically strengthened glass broken, and on the right side there is thermally tempered glass broken. Chemically strengthened glass breaks like regular glass because we do not change the internal part of the glass. We only make the surface stronger, but inside the glass is the same as regular float glass, and it breaks just like it. Thermally tempered glass changes the internal structure of the glass and it breaks into very small pieces. In many cases it is better because it is safer for humans, that is why we normally use thermally tempered glass in cars or in places where broken glass may injure people.

Another property or type of glass that we will talk about is Optiwhite and Float. Float is the most common glass that we use in architecture designs, but also in many touchscreens. The float glass is the most common, most popular and the cheapest, but sometimes we have specific requirements. We sometimes need to have very good color reproduction, especially light colors, white color. Then we use glass called Optiwhite. To achieve that we need to remove the iron from the glass. Float glass has a little bit of iron which makes it green or greenish. If we look straight through the glass, we may not see that but if we look like from an angle, we can see the green color. If we put a white background, we will also see this greenish color a little bit. So, if there are specific requirements, we use Optiwhite, it is especially worth considering if you have a white background. Usually, the Optiwhite is a little bit more expensive, so it is worth checking with the manufacturer of the display what we can use in our case.

Now we know how glass is made, how it is being strengthened, how it breaks and what types of glass, Float and Optiwhite, we have. To continue, we will talk about surface treatments other than strengthening. The other treatments that we use are anti-glare, anti-fingerprint, anti-reflective and anti-bacterial. About anti-reflective treatment we have talked in another video about

On the picture above there are examples of glass. One of them is a little bit blurry, it is anti-glare and the other one is clear – it is anti-reflective. In the past, anti-glare glass was more popular and used in some commercial devices, but later manufacturers have found that devices with anti-glare are being sold less frequently than the glare ones. It is because as humans we think that there is something wrong with a little bit blurry image even if the reflections are lower. When we are in a shop and looking at phones, we do not see the image clearly and we think that there is something wrong and we do not want this device. That is why we do not see any more anti-glare glass in consumer products. Everything is glare in consumer products, it could be anti-reflective or could be only regular without any surface treatment. But in the professional market that we are working on, like medical devices, military devices, we have many projects where we use anti-glare and anti-reflective treatments, both solutions to reduce reflections and increase contrast.

Now let us talk about hardness of glass in TFT LCD displays. Of course, to talk about hardness we need to measure it. For that we have the Mohs scale where we have 11 different levels of hardness. Like you see on the picture above, the 10th  is diamond and the 1st  is talk. What we normally use is glass with hardness between 5 and 7. In some cases we also use Gorilla glass with hardness 9. It is used on our phones or tablets. As you can see, we can achieve hardness 7 with chemically strengthened glass and usually 6 with thermally strengthened glass. Gorilla glass is also chemically strengthened glass, patented by the Corning company and it is the strongest that we can achieve in the cover glass to protect the screen.

This scale is about surface hardness – how hard is it to scratch the surface. As you know, even glass with hardness 9 can be scratched, everybody has some scratches on their phone because this hard layer is very thin – 10 micrometers only. If we put enough force and break this barrier, then we have soft glass with hardness 6 or even lower, that is why we have the scratches.

A couple more words about Gorilla glass. Now there is the sixth generation of Gorilla Glass on the market. The goal for Corning company and Gorilla Glass is to make the glass as strong and as light as possible, because most of the cases are handheld devices, where we want the glass to be light, that is why we want to make it very thin. We have also other companies that are making equivalents of Gorilla Glass, like Dragontrail from AGC or Xensation from Shott. They are not so popular but in many mobile phones or tablets on the market you can find these types of glass.

Now let us talk about the painting. We know the types of glass that we use in TFT LCD displays, we know how to make the glass stronger, we know the surface treatments, how to make the glass less reflective or anti-fingerprint or antibacterial, but it is not enough because glass will only be transparent. If we want to cover it, we need to paint it. Typically, we paint glass with the technique called Screen Printing. It is the most popular, cheapest and fastest technique.

When we do the Screen Printing, we need a screen for each color, so to minimize cost, we try to reduce the number of colors to 2–4, like the background and the colored logo. Each color is a different process, we need to wait until the previous painting dries and then we need to put another screen and print another color. More colors mean a longer process and of course a higher cost. Of course, we can change the shape of the glass, we can make rounded corners or custom design of the glass, but it is expensive because first it is just the rectangular piece, then you need to go to the CNC machine to make the proper shape of the glass.

Now we will talk about mechanical impact protection. It is different than the surface hardness we talked about before. On the picture above, we have the test and scale to measure the mechanical strength of glass, that means how much energy we can put on the glass before it breaks. It is measured in IK rate. IK rate is a scale where we have different levels and different energy that will boost. For example, if we want to test IK 9, we need to take 5-kilogram mass from 200-millimeter height. The mass is kept above the tested glass using an electromagnet, then we just drop it, and we see if it breaks or not. If not, of course the test is passed.

If the glass has not passed the test, we can try to change the glass type from thermally tempered to chemically strengthened or go to a thicker glass.

The last point in this article is laminated glass. We laminate glass because of a few reasons. First, what is laminated glass. Laminated glass is like putting the film inside two glass sheets. This process is expensive, we need pressure, we need temperature, we need time, and we need an exceptionally clean environment, because when we laminate together two sheets of glass, we need to be sure that no particles get inside. This kind of process needs to be done in a Clean Room, so it is expensive, but as you see on the picture above, even if the glass is broken, it still holds up because of the laminated film inside.

We laminate glass mainly because of two reasons. One is mechanical strength and impact. We use it even in our homes. Many windows used nowadays are anti-vandal and that means they are laminated glass, and they are extraordinarily strong. The other reason to laminate glass is to put a film inside with some properties, usually to block the UV or IR light. IR means infrared so heat and UV means ultraviolet, short wavelength, extremely dangerous for electronics. When we have an outdoor application, some customers want to protect the displays, touchscreens or the e-paper displays also against UV. Then we use laminated glass and as you can see on the chart above the IR cut film and UV cut film are both transparent for visible light. We can see everything through them, but what is higher and what is lower is cut by UV and IR films. Most often we use only UV cut film because UV is more dangerous, for example it makes the film sensors for capacitive touchscreens turn yellow or it can decrease the contrast of the TFT (Thin Film Transistor) display by damaging the polarizer or color filters. The IR film is used in some applications to protect the display from heat. If we add it, we can decrease the temperature of the display surface. In another video we were talking about High-TN, so liquid crystals that can work in very high temperatures. For this kind of liquid crystals, we usually do not need to decrease the temperature of the surface because they can go up to 100 or 110 degrees, but regular displays can work up to 50- or 70-degrees maximum temperature. Using the IR cut film can solve the problem with blackening and increasing the display temperature too much.

Several display types are currently used in smartphones, and the most popular touchscreen displays are LCD, TFT, IPS, OLED, AMOLED, Super AMOLED and Retina.

Touchscreen LCDs fall into two categories: resistive or capacitive. Resistive touchscreens react to pressure from a finger, fingernail, stylus or other hard objects. The lack of multi-touch functionality, however, has limited resistive displays mostly to lower-end devices. Capacitive touchscreens, meanwhile, support multi-touch and are designed to react to the touch of a bare finger. This technology can be found in most mid-range to high-end smartphone and tablet displays, and users generally appreciate the smooth swiping motions and intuitive interface.

Thin Film Transistor, aka TFT LCD displays are superior to previous LCDs, delivering higher resolution and better image quality. On the other hand, TFT displays deliver poor visibility in bright light and have narrow viewing angles. This technology is typically found in budget phones or low-end smartphones.

In Plane Switching, aka IPS LCD technology delivers better viewing angles compared with TFT, while also drawing less power to allow for more battery efficiency. IPS displays typically cost more to make, however, and that"s why they"re typically used in higher-quality smartphones that come with a price to match. On the plus side, IPS is the most advanced type of LCD display tech and delivers notably wider viewing angles, extremely accurate color reproduction.

AMOLED, meanwhile, stands for Active-Matrix Organic Light-Emitting Diode. AMOLED and Super AMOLED technology is more expensive and is used only in high-end flagships, offering a number of benefits. This display technology delivers bright and vivid colors, great battery efficiency and wide viewing angles, while also allowing for lighter displays.

LCD and AMOLED are the most commonly used display types in current smartphones and tablets. LCDs are backlit, battery efficient, very bright, and extremely precise in displaying the entire color spectrum, which contributed to its wide popularity. AMOLED, however, eliminates the need for backlighting because each sub-pixel creates its own light. Compared to LCD, AMOLED may at times deliver less accurate colors and less visibility in direct sunlight.

In addition to the various types of display technology, many smartphones also use Gorilla Glass protection to increase their durability. Gorilla Glass is a tough, protective glass sheet that"s highly resistant to damage. Used on many smartphones from Samsung, Motorola, Nokia and others, Gorilla Glass can provide good protection against scratches, bumps and drops, thus increasing the device"s durability.

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.

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.

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:

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.

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.

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.

The Xiaomi Mi 11 Lite runs on Snapdragon 732G chipset bundled with Adreno 618 GPU and up to 8GB RAM. The display front comes with a 6.55-inch AMOLED display with HDR 10+ support and 402 PPI.

OPPO has recently launched the Oppo Reno 6 Pro with MediaTek’s Density 1200 chipset coupled with Mali-G77 MC9 GPU and up to 12GB of RAM. In addition, it comes with a 6.55-inch curved AMOLED FHD+ display with support for HDR 10+ and an Oleophobic coating.

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.

Another critical advantage of OLED tech is high contrast ratios. Technically, OLED displays offer "infinite contrast," or 1,000,000:1 contrast ratios. This is because OLED displays reproduce black by turning off pixels entirely, and contrast is measured by comparing the brightest part of the screen to the darkest part. Improved contrast makes on-screen content more vivid and makes bright highlights look more impressive. This also means that OLED screens can reach higher brightness than the best IPS LCD screens.

OLED displays can display more colors with greater color accuracy than their LCD peers. This is great for photographers and videographers using their phones to preview, edit, and create content.

OLED displays have near-instantaneous pixel response times. Older LCD screens often have lower response times because to change from one color to another, they must physically change the orientation of a liquid crystal, which takes time. An OLED display turns a subpixel on or off with an electrical charge, giving them a faster pixel response time.

The omission of a separate backlight and the use of fewer components means OLED displays can be thinner than LCDs, making them more versatile in their applications. This means they are more fragile and prone to damage in high-impact or high-stress situations. Engineers combat this by using technologies like Gorilla Glass and robust metal frames. Mitigation strategies like these raise the cost of OLED screens.

OLED displays can also be transparent, depending on the materials used. Transparent displays are helpful for in-display fingerprint readers and under-display cameras, which allow manufacturers to design smartphones with fewer and smaller bezels, notches, and display cutouts. When notches and cutouts are necessary, OLED displays have more even brightness around those cutouts and notches compared with LCDs, where the backlight has to make it around the cutout, and things get a little messy.

Of particular import to smartphones, OLED displays often consume less power, especially when displaying dark images or UI elements, thanks to the pixel-level regulation of brightness. However, at max brightness, an OLED screen usually uses more power than an equivalent LCD.

Early OLED screens placed all the organic materials on a glass substrate. However, glass is rigid, so a flexible plastic substrate is needed to create foldable display screens, leading to the creation of POLED screens.

POLED (polymer organic light-emitting diode) offers advantages in terms of durability and versatility. The replacement ofglass substrates with plastic ones makes them more shock-resistant. Another unique advantage is in the implementation. Designers can reduce bezel size by folding the electronics underneath an edge of the display instead of having it be on the same plane. POLED displays are also significantly thinner than OLED displays with glass substrates.

Thin-film transistor (TFT) arrays used in modern active-matrix OLED displays control the charging of the display"s storage capacitors. These TFTs control current flow, resulting in more energy-efficient OLED panels than PMOLED displays. This allows a larger display size without compromising resolution, lifetime, or power consumption.

QLED is found in TVs and large computer monitors because that"s where it sees the most benefit. OLED displays in phones are small enough, bright enough, and cheap enough that QLED wouldn"t be able to compete or offer any practical benefit to the end user.

If we expand the term AMOLED, we get Active-Matrix Organic Light-Emitting Diode. AMOLED display technology is now used in many smartphones and televisions especially in the Samsung products. By the use of this technology, the capacitive touchscreen layer is directly integrated into display. Traditionally the touchscreen layer is overlaid on the top of the display. As such, the AMOLED screen gets an advantage over ordinary capacitive touchscreen because it is possible to manufacture a thinner design. The AMOLED screen uses less power and reflects less light and therefore it gives a very good performance when you use your smartphone outdoors and in more light. In addition to smartphones, the technology has been very useful in manufacturing low-power, low cost devices especially devices with large screens. AMOLED screens have better contrast ratios than the LCD screens. LCD displays are better in direct sunlight when compared to the ordinary AMOLED display. But Samsung"s Super AMOLED display technology has overcome this defect by reducing the size of gaps between the layers of the screen. As such Super AMOLED is the term used by Samsung for AMOLED display whereby the layer that detects the touch is integrated directly into the screen in stead of overlaying it on the top of the screen.

The U.S. glassmaker Corning has manufactured an alkali-aluminosilicate sheet glass and has registered the patent under the name of Gorilla. This glass is commonly known as Gorilla glass. It is used as a cover glass for most of the electronic gadgets. The maximum use of this technology is in devices like mobile phones, portable media players and laptop computer displays and even on some television screens. The glass is very thin, light and damage resistant. By 2010, the Gorilla glass came to used in about 20 per cent of the mobile hand sets manufactured in the world. Gorilla Glass 2 which is second generation glass from Corning was introduced in the market in 2012. Corning announced on October 24, 2012 that one billion mobile devices used its product called Gorilla Glass. It is rumoured that the third generation protective glass Gorilla Glass 3 will be used in the devices from 2013 onwards. The best feature of Gorilla Glass 3 is that it is three times more scratch resistance that Gorilla Glass 2. So we now know that Gorilla Glass is the protection for the display screen. Corning has also launched some other glass protections like Lotus Glass and Willow Glass."Teaching is my passion & sharing of knowledge is my motto"

Rest, the device runs on a Snapdragon 888 chipset, 12GB LPDDR5 RAM, 256/512GB UFS 3.1 storage, 4400mAh with 25W fast charging, and a penta-camera setup.

It ships with Snapdragon 888+ processor, 8GB/12GB RAM, 128GB/512GB storage, 4,500mAh battery and has 120W wired charging, 108MP camera, and Harman/Kardon speakers.

Asus Zenfone 8 Flip has a 6.67-inch (2400 × 1080 pixels) Full HD+ E4 AMOLED HDR10+ display with 90Hz refresh rate, 200Hz touch sampling rate, 110% DCI-P3 color coverage, up to 1000 nits brightness, and Corning Gorilla Glass 6 protection. This full screen fascia is possible thanks to a flip camera module.

The 90Hz refresh rate makes it super smooth, the resolution goes all the way up to 2K, and, there are those slick curves at the edges. The phone is powered by Snapdragon 855 octa-core chipset paired with high-quality UFS 3.1 storage and LPDDR4X RAM. On the downside, the 7 Pro is big and bulky, is missing the audio jack, and has a mediocre set of cameras.

The Galaxy A80 is the only phone from Samsung with an AMOLED screen that extends edge to edge. Yes, even the high-end S-series and Note-series flagships rely on cutouts or punch holes to accommodate the front camera.

The 6Z (globally known as the Zenfone 6) is one of the most impressive phones we have seen from Asus in India. The 6Z (review) has a gorgeous and well-calibrated IPS LCD display that covers the entire facia. The selfie camera is housed in a flip module and this glass body phone houses a massive 5000mAh battery while being reasonably manageable.

The 6.4-inch screen has Full HD resolution which is quite sharp considering this is an IPS LCD and not AMOLED screen. This competitively priced Snapdragon 855-powered phone also has stereo speakers, 48MP primary camera, and runs an extremely close-to-stock version of Zen UI.

Oppo Reno, which is a trimmed-down version of the Oppo Reno 10X Zoom, has the same design with shark-fin pop-up and is also slimmer and significantly lighter. The handset has a 6.4-inch AMOLED display (Full HD) with around 87% screen-to-body ratio that targets DCI-P3 color gamut and is shielded by Gorilla Glass variant.

This one is missing 10X lossless zoom and Snapdragon 855, but the 48MP primary rear camera and SD 710 chipset should still be a good deal for light and moderate user.

Motorola One Fusion Plus rocks a 6.5-inch full HD+ notch-less TFT-LCD screen. It’s pop-up camera houses a 16MP sensor. Pivot and by the back you get a 64MP quartet.

The handset also comes in catchy onion and garlic gradients that look extremely premium. Other highlights include VOOC 3.0 fast charging, 48MP rear camera, and Snapdragon 710 chipset.

Huawei Y9 Prime is the first Huawei phone in India to deliver a full-view screen. The IPS LCD display on the phone measures 6.59-inch and is full HD sharp.

The handset is powered by Kirin 710 octa-core chipset paired with 4GB RAM and 128GB storage. Other features include triple rear cameras, 4000mAh battery, and Android Pie based EMUI 10 software.
