AG is the abbreviation of "Anti-Glare ". This process applies a special "matte" treatment on the surface of ordinary glass to disperse the concentrated reflection of external light on the glass surface to prevent glare effects-so The glass surface of the AG process has many small dense particles attached and is uneven, but when you brush your fingers on the AG glass, you can feel a very fine frosted feeling. At the same time, it will have a very comfortable and delicate skin-friendly texture. It is not as easy to contaminate fingerprints like ordinary glass.


There are currently three AG processes on glass, spraying, coating and chemical etching:

Spraying is the direct use of equipment to spray a layer of coating on the glass surface to form a concave-convex surface. It has low cost and high efficiency, but it has poor friction resistance.

Coating is first processed on the surface of the polarizer, and then the treated coating is covered on the surface of ordinary glass. The light transmittance is high, but the hardness is low and the touch is average.

Chemical etching is the most expensive of the three. The use of strong acid chemical etching is used to directly process the surface of the glass with concave and convex processing, so that the processing integration is the strongest, and the hardness, life and scratch resistance are also the highest-the lens of the iPhone 12 mini The matrix glass module uses a chemical etching process.


In fact, the hardness of metal is inferior to that of glass, that is to say, normal glass can withstand metal scratches from the surface-so these three lines may not be scratches, just the metal residue left by the metal scratching the surface , So it will be wiped off by the glasses cloth; and the hardness of the skin and nail cover is much lower than that of metal and glass, and it is unlikely that the residue will be wiped off in a short time.

Polyimide is a plastic material suitable for films, coating agents, photosensitive resins, and electrical insulating materials. It is widely used in various fields from electronic parts, automobile parts to artificial satellites and space probes. Polyimide has a higher thermal decomposition temperature (500°C or higher) than other plastic materials. It is not only heat-resistant, but also an excellent material in terms of mechanical and scientific properties. Recently, with the development of under-panel camera and foldable smartphones, the potential as a display material is also increasing.

One of the characteristics of ordinary polyimide is that it has a yellowish-brown color due to its chemical structure, and cannot be used in applications requiring colorless and transparency. The coloring is because the conventional polyimide raw material has an aromatic skeleton (benzene ring skeleton). To make it colorless and transparent, the polyimide raw material (acid dianhydride) can be changed from traditional aromatic monomer to alicyclic monomer. However, such a method cannot maintain sufficient heat resistance and dimensional stability, and therefore it is difficult to use it in the same applications as colored polyimides.

However, in recent years, transparent polyimide has attracted attention as a glass substitute material in liquid crystal displays and organic EL displays.

The industry has also predicted that there will be a transparent polyimide market in the near future since more than 10 years ago.

According to the report, according to previous studies, the virus can still be detected on stainless steel and plastic even after 3 days. In some cases, it can even exist on the surface of smart phone cases and banknotes for several weeks.
Although it is still not proven to be infectious, in order to reduce the potential risk, it is recommended to wash hands or use alcohol for disinfection, and reduce the habit of touching the face with hands to prevent the virus from entering the eyes, mouth or nose.

However, when using high-tech products such as mobile phones, it is difficult to ensure that the surface is always disinfected before use. The equipment must also be in frequent contact with the face and fingers. Perhaps it is an antibacterial business opportunity. iPhone and Android device screens are mainly supplied Shang Kang Ning recently announced its own new invention. Through this new coating technology called "Corning Guardiant", glass ceramic materials will have higher antibacterial activity.
According to Corning, Corning Guardiant is a new breakthrough technology. By adding copper additives to the surface of the existing glass ceramic material, the coating can kill 99.9% of bacteria and viruses, and has a highly durable antibacterial activity against the new coronavirus. Even in a 6-year wiping scenario, the paint is still effective against viruses.

Not only the new coronavirus that caused this year’s epidemic, research has shown that Corning Guardiant can also remove Staphylococcus aureus, Pseudomonas aeruginosa, or norovirus, which is considered the most difficult to kill, in less than 2 hours, even on wet and dry surfaces. It has the same bactericidal effect. In contrast, products using silver and zinc are only effective on wet contaminated surfaces.

It’s not yet certain when products using Corning Guardiant will come out, and what high-tech products we can see it in. However, according to Corning’s statement, they are cooperating with the PPG industry to report to the U.S. Environmental Protection Agency (EPA) Provide registration application. Before approval, new PPG coated products will be provided under the name Copper Armor.
