Abstract

The invention provides a repaired array substrate, a repairing method and a display panel. The repaired array substrate comprises a substrate body, data lines, scanning lines and thin film transistors, the data lines, the scanning lines and the thin film transistors are arranged on the substrate body, the data lines and the scanning lines are arranged in a criss-cross mode and define a plurality of pixel areas, and each pixel area is internally provided with the corresponding thin film transistor; the thin film transistor comprises a grid electrode arranged on the substrate and connected withthe scanning line, a grid insulating layer covering the grid electrode, an active island arranged on the grid insulating layer and a passivation layer covering the active island; a groove is formed inthe passivation layer in the pixel area with defect points, and the groove is filled with a lightproof coating, so that the pixel area with the defect points is in a dark spot state through the lightproof coating. The repaired array substrate provided by the invention is suitable for repairing the bright spot defects generated in each production process step, and the repairing structure and the repairing process are relatively simple.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a repaired array substrate, a repair method, and a display panel. Background technique [0002] A liquid crystal display panel is usually composed of an array substrate, a color filter substrate, and a liquid crystal layer sandwiched between the array substrate and the color filter substrate. By applying a driving voltage between the array substrate and the color filter substrate, the liquid crystal layer can be controlled. The liquid crystal molecules rotate to refract the light from the backlight module to produce a picture. [0003] In a liquid crystal display panel, the array substrate is divided by a plurality of data lines and scanning lines criss-crossing to form a plurality of pixel areas arranged in an array, and each pixel area is equipped with a thin film transistor (Thin Film Transistor, referred to as: TFT). The scanning lines provide switching signal...
