In addition to thinness and display effect, what other key performance indicators are there for Ultra-Thin LCD Panel Substrate Glass?

In addition to thinness and display effect, Ultra-Thin LCD Panel Substrate Glass has several key performance indicators. The thermal expansion coefficient refers to the ratio of the volume or length of the material to the temperature change when the temperature changes. For LCD panels, since they will experience multiple temperature changes during manufacturing and use, the thermal expansion coefficient of the substrate glass must match that of other materials in the panel to avoid dimensional changes or internal stress caused by thermal expansion and contraction. A low thermal expansion coefficient helps reduce the dimensional changes of the panel when the temperature changes, thereby improving the stability and reliability of the panel.
Chemical stability refers to the ability of a material to resist corrosion or chemical reactions in a chemical environment. During the manufacturing process of LCD panels, the substrate glass undergoes a variety of chemical treatments, such as etching and cleaning. Therefore, the substrate glass must have good chemical stability to withstand these treatments without deterioration or damage. High chemical stability helps to extend the service life of the LCD panel and reduce performance degradation or failure caused by chemical corrosion.
Optical properties include transmittance, reflectivity, refractive index, etc., which determine the transmission and reflection characteristics of the material to light. For liquid crystal panels, transmittance is one of the important indicators to measure their display effects. As an important component of liquid crystal panels, the optical properties of substrate glass have an important impact on the overall display effect. High transmittance and low reflectivity help improve the brightness and contrast of liquid crystal panels, thereby improving the display effect.
Electrical properties include resistivity, dielectric constant, etc., which determine the behavior of materials in electric fields. For liquid crystal panels, substrate glass needs to have a certain conductivity to support the production of pixel electrodes and signal lines. At the same time, the dielectric constant of substrate glass also affects the arrangement and response time of liquid crystal molecules. Appropriate electrical properties help ensure that the pixel electrodes and signal lines of liquid crystal panels have good conductivity and signal transmission performance, thereby improving the response speed and stability of the panel.
Mechanical strength refers to the ability of a material to resist external forces without damage. Liquid crystal panels may be affected by various external forces during use, such as vibration, impact, etc. Therefore, the substrate glass must have a certain mechanical strength to withstand these external forces without breaking or deforming. High mechanical strength helps to improve the durability and impact resistance of liquid crystal panels and reduce damage or failure caused by external forces.
Surface quality refers to the flatness, smoothness and other properties of the material surface. The display effect and pixel quality of the LCD panel depend largely on the surface quality of the substrate glass. High surface quality helps reduce pixel defects and display unevenness, and improves the display effect and visual quality of the LCD panel.
