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.
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 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.
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.
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.

When you look at a display device – your phone, your TV, your smartwatch, the screen in your car – what do you see? You see the image. A bright, vivid image on surfaces of all shapes and sizes. Flat, curved, flexible, thinner than ever before.
When you stop and think about what goes into displaying one of these amazing images, you might recognize most are protected by a glass cover. You might even be familiar with display types like LCD or OLED. Yet for many, the recognition stops there. You may see the image on the surface, but rarely think about what creates that image, how it achieves life-like, vibrant color, and the journey it makes to reach our eyes.
If we look deeper, beyond the surface and the cover glass of our devices, we would find one or more layers of ultra-thin, technical glass make such images possible. Each layer with a different purpose, all working together to deliver the beautiful, thin displays we use each and every day. Combined, these layers form what we at Corning call the “glass stack.”
It’s worth looking at the individual layers of the glass stack, since each layer is the result of breakthroughs in glass science, optical physics, and state of the art manufacturing. At the top of the stack, we have the protective cover glass of a mobile device that most consumers have heard of – Corning Gorilla Glass. This cover glass protects and maintains the appearance of the display, and also supports the use of front-facing cameras and various sensors. Often, the rear side of such devices is covered with a similar protective glass, which also allows for wireless charging.
A layer deeper, beneath the surface of the glass cover, are the substrates that serve very specific functions depending on the type of display being created.
Though each layer of the glass stack is formed with the same fusion manufacturing process, the compositions of the glass are different – allowing for different properties and benefits. LCD and OLED displays, whether on mobile devices with glass cover and back or otherwise, utilize different super-thin layers of glass specific to their applications:
