Glass substrate for display and manufacturing method thereof

Abstract

The invention provides a glass substrate for a display and belongs to the technical field of liquid crystal display. The glass substrate is processed through vapor deposition equipment. The glass substrate comprises an optical compensation film. The optical compensation film has higher transmittance of light in a compensation area compared with other areas. The shape and position of the compensation area are designed to be adapted to the shape and position of the unevenly heated areas, caused by the vapor deposition equipment, on the glass substrate. The invention further provides a manufacturing method of the glass substrate. According to the glass substrate for the display and the manufacturing method of the glass substrate, the defects of an existing glass substrate are overcome effectively and accurately, and meanwhile unevenness of colors on a display panel is relieved.

Description

technical field [0001] The present invention relates to a glass substrate for a display and a manufacturing method thereof, which is especially suitable for a glass substrate processed by vapor deposition equipment. Background technique [0002] Modern science and technology need to use a large number of new materials with different functions. These functional materials must be high-purity, or doped materials formed by intentionally doping some impurities in high-purity materials. However, many traditional preparation methods, such as high-temperature smelting, precipitation and crystallization in aqueous solution, are often difficult to meet these requirements, and it is difficult to ensure high-purity products. [0003] Chemical vapor deposition (Chemical vapor deposition, referred to as CVD) is a process technology in which reactant substances undergo a chemical reaction under gaseous conditions to form a solid substance that is deposited on the surface of a heated solid ...

Problems solved by technology

Correspondingly, during the vapor deposition process of the glass substrate 1, the existence of the ejector pin 2 and the resistance wire 3 will cause the glass substrate 1 to be heated unevenly, usually because the temperature at the position corresponding to the resistance wire 3 is relatively high. The temperature at the position corresponding to the ejector pin 2 is low, which affects the process quality and optical properties of the glass substrate

Usually, the glass substrate processed by the vapor deposition process has low light transmittance at the position corresponding to the ejector pin 2 or the resistance wire 3, resulting in a display panel with a chromatic aberration (mura) phenomenon.

This greatly reduces the performance and value of the display panel
