Title:
METHOD FOR RESTORING PIXEL WITH BRIGHT SPOT DEFECT, ARRAY SUBSTRATE, AND LIQUID CRYSTAL PANEL
Document Type and Number:
WIPO Patent Application WO/2017/079943
Kind Code:
A1
Abstract:
A method for restoring a pixel with a bright spot defect, an array substrate, and a liquid crystal panel. The method comprises: making a pixel electrode (113) in connection and contact with a drain electrode (112b) of a thin film transistor by means of dotting and fusion in a via hole; cutting off and separating a continuous common electrode (130) so that the common electrode (130) located in a switch region (10a) and the common electrode (130) located in a pixel region (10b) are separated from each other; removing the pixel electrode (113) located above a position where the common electrode (130) is cut off and separated, and connecting the pixel electrode (113) located in the switch region (10a) and the pixel electrode (113) located in the pixel region (10b) to each other. By cutting off and separating the common electrodes (130) located in the switch region (10a) and in the pixel region (10b), a bright spot defect of a pixel is eliminated, and the pixel having the bright spot defect is restored to a pixel capable of emitting light normally.
