Abstract

The invention discloses a disconnection repair method, a substrate and a display device, belonging to the field of displays. The method includes: forming a conductive polymer precursor film in a broken line area of ​​the conductive line, the broken line area includes at least one pair of conductive points, each pair of conductive points includes two conductive points disconnected from each other, and the conductive polymer precursor film Contacting at least one pair of conductive points; performing light treatment on the conductive polymer precursor film, so that the conductive polymer precursor film between each pair of conductive points undergoes photopolymerization to form a conductive polymer. The conductive polymer precursor film is photopolymerized by light to form a conductive polymer, so that a conductive polymer line is generated between each pair of conductive points, and each pair of conductive points is connected to realize circuit repair without using laser chemistry. Vapor deposition, low repair cost and short repair time, will not affect the performance of pixel units around the disconnected area.

Description

technical field [0001] The invention relates to the field of displays, in particular to a disconnection repair method, a substrate and a display device. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) uses the change of the electric field intensity on the liquid crystal molecular layer loaded between the upper and lower substrates to change the orientation of the liquid crystal molecules, thereby controlling the intensity of light transmission. A display device to display images. A liquid crystal display panel generally includes an array substrate, a color filter (Color Filter, CF) substrate, and a layer of liquid crystal molecules filled in a liquid crystal cell formed by the two substrates. A large number of pixel units are arranged in an array on the array substrate, and each pixel unit includes a TFT; usually, the TFTs of each row of pixel units are connected to a horizontally arranged gate line, and the gate line is used to control t...
