Problems solved by technology

[0007] Conventional dark spot treatment mostly uses laser (Laser) to cut the TFT on the array substrate into dark spots or short-circuit with surrounding pixels to make dark spots, but this laser repair method will cause the film layer to be damaged. In addition, the laser repair method cannot be applied to the optically active bright spot defects caused by scratches on the

Abstract

The invention provides a display panel bright spot fixing method. After a display panel with to-be-fixed bright spots is lighted with a lighting machine, the positions of the bright spots are determined, then particle injection is performed on a polarizer through a particle injection probe of a fixing machine according to the positions of the bright spots, and the area, corresponding to the positions of the bright spots and subjected to particle injection, of the polarizer is free of polarization and light transmittance so as to fix the bright spots. Compared with the existing method for fixing the bright spots with laser, the method has the advantages that damage is not caused to the film layer of the display panel, fixing success rate can be increased, and further product reliability and quality can be improved effectively.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for repairing bright spots of a display panel. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module (Backlight Module). The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of the liqui...
