Abstract

The invention discloses a silicate glass substrate for a flat-panel display. The glass substrate comprises the following components by molar percent: 64-70% of SiO2, 12-16% of Al2O3, 3-8.5% of B2O3, 6.5-9.5% of CaO, 2.5-5% of SrO and 0.02-0.1% of SnO. The glass substrate disclosed by the invention is the silicate glass substrate for the flat-panel display having the advantages of relatively high strain point, relatively low melting temperature, relatively low liquidus temperature and environmental friendliness, and is especially applicable for glass substrates for low-temperature polysilicon thin-film transistor liquid crystal displays (LTPSTFT-LCD) and glass substrates for organic electroluminescence (OEL) displays.

Description

technical field

[0001] The invention belongs to the field of glass manufacturing, and relates to an alkaline-earth aluminoborosilicate glass component, which can be widely used in the production of glass substrates for flat-panel displays, and is especially suitable for low-temperature polysilicon thin-film transistor liquid crystal display (LTPS TFT-LCD) substrate glass and Organic electroluminescent display (OEL) substrate glass. Background technique

[0002] With the rapid development of the flat panel display industry, the demand for various display devices is increasing, such as active matrix liquid crystal display (AMLCD), organic light emitting diode (OLED) and active matrix liquid crystal display (LTPS TFT- LCD) devices, which are based on thin-film transistor (TFT) technology using thin-film semiconductor materials. Silicon-based TFT can be divided into amorphous silicon (a-Si) TFT, polycrystalline silicon (p-Si) TFT and single crystal silicon (SCS) TFT, among whic...
