Problems solved by technology

However, when a compensation film is added to a large-sized liquid crystal display panel to increase the viewing angle, the repaired pixel unit is likely to form a bright spot at a certain viewing angle due to light leakage.

Description

technical field [0001] The invention relates to a repair method of an active element array substrate and a pixel unit thereof, and particularly relates to a repair method of an active element array substrate with redundant active devices and a pixel unit thereof. Background technique [0002] Since the invention of the first black-and-white television with a cathode ray tube (Cathode Ray Tube, CRT) working mode, display technology has been evolving at a rapid pace. However, due to the disadvantages of large size, heavy weight, high radiation and poor image quality of displays made of cathode ray tubes, new flat-panel display technologies are constantly being developed. Among these flat panel display technologies, the liquid crystal display (Liquid Crystal Display, LCD) technology, which has the advantages of thinness, lightness, power saving, low radiation, full color and portability, is the most sophisticated and popularized. For example, mobile phones, digital cameras, di...
