Problems solved by technology
[0003] Usually, during the production process of the LCD panel, it needs to be in contact with equipment of different manufacturing processes. The surface of the LCD panel may be scratched by abnormal equipment, which will have a certain impact on the display quality of the panel, and even cause the panel to be scrapped.
[0004] The existing general companies use automatic grinding and repairing equipment to repair the scratches on the surface of the LCD panel. However, the automatic grinding and repairing panel mainly has the following problems: 1. Low production capacity 2. High failure rate 3. Production high cost
[0006] figure 1 The automatic grinding shown has the following disadvantages because it needs to grind the panel on the scratched side: ① Long processing time and low production efficiency; ② High production cost; ③ High equipment failure rate, which affects the utilization rate

The invention provides a repairing method of a liquid crystal panel. The repairing method is used for repairing scratch of the liquid crystal panel and adopts a method of holding a grinder by hands, a grinding pad serves as a tool, grinding agents serve as the media, and grinding repairing is performed on the periphery of the scratch. By means of the method, grinding repairing is performed manually, the scratch portion of the panel small in scratch is locally grinded, the grinding pad serves as the tool, the grinding agents serve as the media, the periphery of the scratch is processed for smoothing the scratch, and the aim of eliminating the scratch is achieved. The repairing method of the liquid crystal panel has the advantages of being short in processing time, high in production efficiency and easy to operate; and low in production cost.
Description
technical field [0001] The invention relates to a liquid crystal panel technology, in particular to a method for repairing scratches on the surface of a liquid crystal panel. Background technique [0002] At present, a thin film transistor liquid crystal display (ThinFilm Transistor Liquid Crystal Display, TFT-LCD) has become the most important display terminal in the display field. The key component of TFT-LCD is a liquid crystal panel formed by laminating an array substrate and a color filter substrate. [0003] Usually, during the production process of the LCD panel, it needs to be in contact with equipment of different manufacturing processes. The surface of the LCD panel may be scratched by abnormal equipment, which will have a certain impact on the display quality of the panel, and even lead to scrapping of the panel. [0004] The existing general companies use automatic grinding and repairing equipment to repair the scratches on the surface of the LCD panel. However,...
