  • Patent number: 11372293
    Abstract: 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.

  • Patent number: 11226525
    Abstract: A method for repairing the gate-line disconnection includes: determining a disconnected position of a gate line; determining two connecting elements that are closest to the disconnected position and are respectively located at two sides of the disconnected position along an extending direction of the gate line; selecting one or two sub-pixels electrically connected to the two connecting elements as repair sub-pixels, determining a common electrode line coupled to a common electrode of each repair sub-pixel as a selected common electrode line; forming a communication path between a front portion and a rear portion at the disconnected position to bypass the disconnected position, the communication path including at least the common electrode of each repair sub-pixel and a separate line segment cut from the selected common electrode line; disconnecting the common electrode in the communication path from other common electrodes; and disconnecting each repair sub-pixel from a data line.

  • Patent number: 10606132
    Abstract: 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.
