Patent number: 11372293Abstract: The present disclosure relates to a liquid crystal panel and a repairing method thereof, and a display device. The liquid crystal panel includes an array substrate and a filter substrate, and the repairing method includes: irradiating a pixel which is a bright spot of the liquid crystal panel with laser from one side of the array substrate away from the filter substrate, so that a portion of the array substrate located in the pixel is converted from a light transmitting area into a light shielding area.Type: GrantFiled: March 20, 2020Date of Patent: June 28, 2022Assignees: HEFEI BOE DISPLAY TECHNOLOGY CO, LTD., BOE TECHNOLOGY GROUP CO., LTD.Inventors: Guodong Wu, Ping Chen, Hewei Wang, Song Wu, Chen Tang, Mingming Mu, Junfeng Li, Haitao Hu, Fugai Chen, Shuai Ji, Hao Yu

Patent number: 10606132Abstract: The present disclosure relates to a display panel, a display device, and a method for manufacturing a display panel. The display panel has an electrode region, the electrode region including a substrate, a data line layer, and an isolation layer which are provided on the substrate and alternated in a direction parallel to an upper surface of the substrate, wherein the height of the data line layer is equal to the height of the isolation layer. Since there is no height difference between the data line layer and the spacer layer and there is no groove, the possibility that conductive foreign objects are accumulated at the isolation layer at this time is greatly reduced, the smooth surface is more conducive to the movement of foreign objects, and a cleaning tape can remove the foreign objects.Type: GrantFiled: June 1, 2016Date of Patent: March 31, 2020Assignees: BOE TECHNOLOGY GROUP CO., LTD., HEFEI XINSHENG OPTOELECTRONICS TECHNOLOGY CO., LTD.Inventors: Hewei Wang, Lei Han, Peng Jiang, Dong Guo, Nanhong Zhang
