Embodiment Construction

[0079] The specific embodiment of the present invention and its comparative effect with the prior art are now described in the form of examples.

[0080] Table 1 and Table 2 (Example 1 to Example 10) show the composition and characteristics of the glass samples made according to the present invention, that is, the embodiments of the present invention. Table 1 corresponds to the glass composition range disclosed in the present invention when only the basic physical properties required by the TFT-LCD glass substrate are provided. Table 2 corresponds to the glass composition range disclosed in the present invention when the TFT-LCD glass substrate characteristics required by next-generation processes or products such as polysilicon (poly-Si) TFT-LCD are still available. Table 3 and Table 4 (Example 11 to Example 16) show compositions and properties different from the glass samples made in the present invention, that is, comparative examples of the present invention. Among them, Ta...

Description

technical field [0001] The invention relates to a boroaluminosilicate glass formula, which can be applied to the glass for producing flat panel display glass substrates, especially the glass for producing liquid crystal display (LCD) glass substrates. Background technique [0002] LCD is a flat-panel display device that relies on external light sources for illumination, and is mainly composed of two glass substrates and liquid crystals. According to its pixel driving mode, it can be divided into two types: passive matrix addressing mode and active matrix addressing mode. [0003] At present, the common LCDs on the market are Super Twisted Nematic (STN) and Thin Film Transistor (TFT). The STN type belongs to the passive matrix addressing mode, while the TFT type belongs to the active matrix addressing mode. Because the display effect is better than that of the STN type Better, especially the mainstream in the market. The TFT type is often divided into two configurations: am...
