tft lcd ips vs gorilla glass quotation

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.

Hi all, I"ve done some research on tft vs IPS screens and it seems tft screens are the worst type around. With that said, all the videos and articles I found were from 5ish years ago. Are tft screens still garbage? If so, why in the world would Motorola put it in their flagship?

I have noticed that distributors for small and medium TFT, they consider TFT still a top quality product, it"s enough to see product list of any online distributor like

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.

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.

Key Difference: AMOLED is a type of screen used in consumer electronics, such as smartphones, tablets, and laptops. Gorilla Glass is a type of protection that is used on the screen.

There are many different types of screens available, such as TFT LCD, IPS-LCD, Resistive Touchscreen LCD, OLED, AMOLED, Super AMOLED, etc. Each of these types has something that helps them stand apart from the others.

AMOLED stands for Active-Matrix Organic Light-Emitting Diode or "Active Matrix OLED" for short. It is a hybrid display technology that combines the active matrix backplane from a traditional TFT display with an OLED display. The advantage of this is that it has a faster pixel switching response time than the traditional OLED displays.

As compared to other screens on the market, AMOLED has a faster pixel switching response than traditional OLED displays, consumes less power and has better contrast ratios than LCDs. However, AMOLED displays may be difficult to view in direct sunlight as they have reduced brightness. Also organic materials used in AMOLED displays are very prone to degradation, which may result is fading of one color over the others.

As anyone with a cracked screen knows, displays are very easy to damage. Hence, it is essential that the companies that charge so much for their product provide some form of protection on their screens. This is where Gorilla Glass comes in.

Gorilla Glass is an alkali-aluminosilicate sheet toughened glass. It is scratch resistant as well as impact resistant, which means that it will protect the display of the device against the accidental scratches made with keys in the pocket or accidentally dropping the phone.

Gorilla Glass was developed and is manufactured by Corning Inc. It was developed from a chemically strengthened glass called "Chemcor" that Corning developed in the 1960’s. Today, Gorilla Glass is used primarily for portable electronic devices, including mobile phones, portable media players, portable computer displays, and some television screens.

The main difference between Gorilla Glass and AMOLED is the fact that AMOLED is a type of display used in electronics, whereas Gorilla Glass is a type of toughened glass that acts as a screen protection, usually laid on top of the display such as AMOLED.

On some lower quality LCD screens, you can see bright spots in the middle or on the perimeters of screens. This is caused by uneven light distribution. The downside to using backlights, is that black is never true black, because no matter what, light has to be coming through, so it will never have as dark of a screen as an AMOLED screen. Its comparable to being able to slow a car down to 2 mph versus coming to a complete stop.

LCD (Liquid Crystal Display) displays consist of a matrix of Liquid Crystals. Liquid Crystals do not emit light themselves and are reliant on some form of back-light to illuminate the whole display. As a result LCD displays can be very visible in direct sunlight.

IPS-LCDs provide a superior viewing angle and better color reproduction than non IPS-LCDs due to the layout of the LCD"s themselves. This has become a common display type for mid-range to high-end phones.

OLED & AMOLED utilizes "organic" LEDs which emits light and in the majority of cases does away with the need for the back-light of an LCD display resulting in a potentially thinner panel.

They consume less power as opposed to LCDs which always have the back-light on. When a pixel is "black" on a OLED/AMOLED display the pixel is truly off.

One of the industry’s leading oxide panel makers selected Astra Glass as its backplane glass substrate because it has the inherent fidelity to thrive in high-temperature oxide-TFT glass fabrication for immersive high-performance displays.

That’s pretty much what it is — but you get some other nice bonuses, too. The display is much nicer than those I’ve seen on other Chromebooks at this price. It’s portable at 2.65 pounds, its speakers and microphones are serviceable, and it has a really smooth Gorilla Glass touchpad.

The chassis has some other features you don’t often see at this price point. The keyboard is backlit, which is a huge surprise. It also offers a comfortable typing experience, with satisfying keys that are still quiet. I’m picky about touchpads, but this one is quite roomy, with a smooth Gorilla Glass surface — I’d choose it over plenty of touchpads I’ve used on multi-thousand dollar Windows laptops. And you get a good, modern port selection including two USB Type-C ports (supporting USB 3.2 Gen 1, DisplayPort, and DC-in), one USB 3.2 Gen 1 Type-A, and a 3.5mm combination audio jack. There’s a USB-C on both sides, which I’m very happy about for charging convenience.

For comparison, the Spin 513 is largely competing with Mediatek and Intel Celeron machines. It’s difficult to compare the Snapdragon 7c to these chipsets (in terms of power) because their architecture is completely different. The best I can say is that anecdotally, I had a slightly faster experience on the Flex 3 with the Celeron N4020. Zoom calls were more feasible on that machine (though they were still bad). With that said, I don’t think the difference is noticeable enough to make the Flex 3 a better buy unless you’re really picky. Both devices are really only meant for basic tasks. Think more elementary school level as opposed to high school or college.

The flipside of this low performance is that the Spin’s battery life is really excellent. I averaged 10 hours and 15 minutes to a charge. That was continuous use, with a more intense workload than anyone should really be putting this Chromebook through, and screen brightness at 50 percent. If your brightness will be lower, you’re doing easier things than I am, and you’re taking some breaks (likely on all three counts), I imagine you’ll be able to go a couple days without needing an outlet. The 45W charger is also quite small, and won’t add much weight to your backpack.

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.
