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 panels include glass substrates, optical films, liquid crystal materials, polarizers and other materials. The panels can be divided into three types: LCD panels, OLEDs and mini LEDs. LCD panels require that the glass substrates must be alkali-free glass; and OLED panels in order to achieve Higher resolution, higher brightness, longer service life and other features have higher requirements for glass substrates.


Glass Substrate Processing Technology

The glass substrate production process can be divided into Float Technology, Overflow Fusion Technology and Slot Down Draw. At present, Asahi Glass is the only company in the world, AGC, which uses the float method to manufacture TFT-LCD glass substrates. The current mainstream production process in the industry is the overflow fusion method.
