Abstract

The invention discloses a method for repairing abnormal pixel points of a display panel. The method comprises the following steps: arranging a polarizing plate between the display panel and a screen of a display; searching and marking the abnormal pixel points on the polarizing plate; and changing light polarization structures at the positions of the abnormal pixel points by using specific light. The display problem of abnormal pixel points can be solved.

Description

technical field [0001] The invention relates to the technical field of display panels, in particular to a method for repairing abnormal pixels of a display panel. Background technique [0002] With the development and progress of science and technology, liquid crystal displays have become the mainstream products of displays due to their thin body, power saving and low radiation, and have been widely used. Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal panel and a backlight module. The working principle of the liquid crystal panel is to place liquid crystal molecules between two parallel glass substrates, and apply a driving voltage on the two glass substrates to control the rotation direction of the liquid crystal molecules, so as to refract the light from the backlight module to produce a picture. [0003] Among them, Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has gradually occupi...
