Abstract

The invention provides a method for restoring poor orientation of a liquid crystal display panel. According to the method for restoring poor orientation of the liquid crystal display panel, whether poor orientation occurs in each liquid crystal display panel having implemented an optical orientation process on a liquid crystal display mother board is detected through a camera and a processor, the position of the poor orientation is recorded, the position of the poor orientation is heated through a hot air gun, re-orientation is performed on the liquid crystal display mother board through a UV light source, the poor orientation of the liquid crystal display panel is restored, a gray level difference of the liquid crystal display panel caused by the poor orientation is avoided, the product yield and quality are ensured, and product competitiveness is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for repairing poor alignment of a liquid crystal display panel. Background technique [0002] A liquid crystal display device (LCD, Liquid Crystal Display) has many advantages such as a thin body and power saving, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display panels, which include a liquid crystal display panel and a backlight module (backlight module), and a liquid crystal display panel usually includes: a color filter substrate (ColorFilter Substrate, CF Substrate), A thin film transistor array substrate (Thin Film TransistorArray Substrate, TFT Array Substrate) and a liquid crystal layer (Liquid Crystal Layer) disposed between the two substrates. Generally, pixel electrodes and common electrodes are respectively arranged on the array substrate and the color filter substrate. When a ...
