Glass substrate is an important part of display, widely used in liquid crystal display (LCD), organic light emitting diode (OLED) and other modern display technology. It not only provides mechanical support for the display, but also directly affects the quality and reliability of the display effect.

Glass substrates are usually made of high-purity borosilicate glass or aluminosilicate glass, with high transparency, low coefficient of thermal expansion, and excellent chemical stability. These characteristics ensure that the substrate can withstand high temperature processes and complex physicochemical treatments during production and use.

In LCD, the glass substrate is usually used to clamp the liquid crystal layer between the upper and lower layers, while in OLED, it provides protection and support for the organic light-emitting material. In recent years, with the development of ultra-high definition (4K, 8K) display, flexible screen and micro-display technology, the thickness of the glass substrate tends to be thinner, while requiring higher flatness and surface accuracy to improve the display effect and energy saving performance.

In short, as one of the core materials of display technology, glass substrate is the key to achieve high-quality imaging in modern display equipment.
