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 present invention relates to a boroaluminosilicate glass formulation, which can be used in the production of glass substrates for flat-panel displays, especially glass that can be used in the production of glass substrates for liquid crystal displays (LCDs). Background technique [0002] LCD is a flat display device that relies on external light source illumination and is mainly composed of two glass substrates and liquid crystals. According to its pixel driving method, it can be divided into two types: passive matrix addressing method and active matrix addressing method. [0003] Currently, the common LCDs on the market include super twisted nematic (STN) and thin film transistor (TFT). The STN type belongs to the passive matrix addressing method, while the TFT type belongs to the active matrix addressing method. Since the display effect is better than that of the STN type, Better, especially the mainstream in the market. The TFT type is often d...
