The invention relates to a liquid crystal display panel cutting detection method, which comprises the following steps of: S1, detecting the cutting edge of a display panel; S2, performing electrical color detection on the display panel with qualified edge detection; and S3, performing grade evaluation on the display panel according to the edge cutting condition and the color detection condition. When cutting detection is carried out on the liquid crystal display panel, grade evaluation is carried out on the display panel according to the cutting edge condition and the color detection condition, the cutting quality of the display panel is precisely determined, and a solid foundation is provided for cutting regulation and control of the panel. A central control module is disposed when liquid crystal display panel cutting detection is carried out, and the cutting quality and the quality of the cut display panel are automatically judged through the central control module, manual participation is reduced, and the detection speed is increased.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel cutting detection method. Background technique [0002] In the production process of liquid crystal display panels, it is necessary to test the yield rate, find problems in time and repair them. As smart phones have higher and higher requirements for the resolution of liquid crystal display panels, the technology of using low-temperature polysilicon as the semiconductor material to make TFT array substrates has become the mainstream, and the requirements for the yield detection of liquid crystal display panels have also increased. At present, the method known in the industry to detect the yield rate of liquid crystal display panels is to drive independent liquid crystal display panels one by one. Standing, forming a liquid crystal display mother board including multiple liquid crystal display panels, and then going through a cutting, thinning, sec...
