Liquid crystal display

The glass substrate is a thin glass sheet with an extremely flat surface and is one of the important raw materials for liquid crystal display panels. The key supporting materials of liquid crystal panel include glass substrate, optical film, liquid crystal material, polarizer and other materials. The panel can be divided into LCD panel, OLED and mini LED. The LCD panel requires that the glass substrate must be alkali-free glass. In order to achieve higher resolution, higher brightness, longer service life and other characteristics, OLED panel has higher requirements for glass substrate.

Glass substrate processing technology

Glass substrate production process can be divided into float (Float Technology), overflow fusion method (Overflow Fusion Technology) and flow hole down (Slot Down Draw). At present, the world only Asahi nitrate this enterprise AGC using float to manufacture TFT-LCD glass substrate, the current industry mainstream production process is overflow melting method.
