Factory Cheap Grey Toughened Glass - 1mm 23inch LCD Display Front Cover Glass – Saida

12.5inch to 23inch LCD Display Front Cover Glass with Customized Design for Touch Screen

Description of tempered glass

Tempered glass is a kind of pre-stressed glass, to improve the strength of the glass, typically using a chemical treatment or physical hardening hardening treatment method, form a pressure in the glass surface, the glass surface exposed to external stress when the first offset, thereby improving the carrier ability to enhance glass itself wind pressure resistance, cold and heat resistance, impact resistance and so on.

Advantages of tempered glass

1.Security: When the glass is external damage, Debris will become very small obtuse angle grains and difficult to cause harm to humans.
2.High strength: the impact strength tempered glass of the same thickness of ordinary glass 3 to 5 times more than the ordinary glass ,bending strength 3-5 times.
3.Thermal stability: Tempered glass has good thermal stability, can withstand the temperature is more than 3 times that of ordinary glass, can withstand 200 °C temperature changes.

AG Technique

	List Data Gloss 40-120 Haze 3-20 Transmittance 40%-92% Roughness 0.06-0.34 Abrasion ＞2500 Cycle
Dazzle is the side effect of lighting. It happens when the surrounding light is stronger than that of the screen, which makes user uncomfortable when using the cellphone, Pad, and so on. The newly developed technology – AG（Non-Etching）- to decrease it.

AR Technique

	List Data Transmittance（Max） =99% Transmittance ＞95%  Reflectance 0.5%-4.0% Anti-Heat ＞500° Anti-Scratch ＞7H
AR Coating, with the advanced magnetron-sputtering technology, is to coat anti-reflecting layer on the tempered glass, for efficiently decreasing reflectance but increasing transmittance, making the color through the glass much purer.

AF Technique

	List Data  Friction factor 0.03-0.07 Abrasion ＞3000 Cycle Drop angle ＞110°  Surface energy ～16MJ/㎡  Rubbing ＞2500 Cycle
AF Coating is to make pollutant stick to the surface more difficultly, in order toachieve anti-fingerprint. With the coating layer on it, the glass also becomes anti-scratch

Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase

its strength compared with normal glass.

Tempering puts the outer surfaces into compression and the interior into tension.
