The invention provides a method for repairing a pixel defect of a liquid crystal panel. The method comprises the following steps of providing the liquid crystal panel, wherein the liquid crystal panel comprises a plurality of pixel units; each pixel unit comprises a main pixel and a sub-pixel, and at least one in the plurality of pixel units is provided with a to-be-repaired main pixel defect or sub-pixel defect; judging a defect type of the pixel unit with the defect and carrying out dark repair, and adopting a first repair method to carry out dark repair when the defect type is the main pixel defect; adopting a second repair method to carry out dark repair when the defect type is the sub-pixel defect. The invention also provides the liquid crystal panel. According to the method for repairing the pixel defect of the liquid crystal panel, a dark repair process of the liquid crystal panel can be effectively reduced, the production cost is saved and the product quality is improved.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method for repairing pixel defects of a liquid crystal panel and a liquid crystal panel. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has a semiconductor switch for each pixel unit, and each semiconductor switch can be directly controlled by point pulses, so each pixel unit is relatively It is independent and can be controlled continuously, so that the TFT-LCD has a high response speed, and at the same time can precisely control the display color level, and the display color is more realistic. At present, with the continuous maturity of TFT-LCD display technology, problems such as viewing angle, color saturation, and brightness of TFT-LCD liquid crystal panels have been gradually solved, further accelerating the application of TFT-LCD liquid crystal panels in the display field. [0003] For LCD panels, the viewing angle is ...
