What is tempered glass for LCD protection

What is a Tempered Glass?

Tempered Glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering creates imbalanced internal stresses which cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards. The granular chunks are less likely to cause injury.

What makes Tempered Glass so important?

Toughened glass is used when strength, thermal resistance and safety are important considerations. It is specifically used for touch screen to protect the LCD against heat, impart, chemicals, and vibration. Tempered safety glass often does not fall out of its frame when it breaks because it is manufactured through a process of extreme heating and rapid cooling, making it harder than normal glass.

What are the advantages of having Tempered Glass?

The term toughened glass is generally used to describe fully tempered glass but is sometimes used to describe heat strengthened glass as both types undergo a thermal 'toughening' process. There are two main types of heat treated glass: heat strengthened and fully tempered. Heat strengthened glass is twice as strong as annealed glass while fully tempered glass is typically four to six times the strength of annealed glass and withstands heating in microwave ovens. The difference is the residual stress in the edge and glass surface.  Tempered glass can take a higher load and therefore deflects further before breaking.

TAICENN developped our own tempered glasses, with special AF (Anti-finger print) treatment, and cooperate with our touch screen suppliers.
