  • Patent number: 10908465
    Abstract: An array substrate is provided, comprising a display area and a non-display area outside the display area. The non-display area is provided with a first transistor and a first conductive region electrically connected with the first transistor. A control terminal, and one of a source and a drain of the first transistor are both electrically connected to a data line in the display area, the other of the source and the drain of the first transistor is electrically connected to the first conductive region. For this array substrate, the static electricity generated on the data line in the rubbing process can be led to the first conductive region through the first transistor, so as to prevent the static electricity from being transmitted to the display area, which could have destroyed the TFT device in the display area.
    Type: Grant

  • Patent number: 9921449
    Abstract: An array substrate and a display device are disclosed. The array substrate includes a display area and a gate driver circuit located outside of the display area. The display area is covered with an alignment film, and the gate driver circuit is also covered with the alignment film. With the array substrate, damage, caused by static electricity generated between conductive particles in a sealant and the gate driver circuit, to the gate driver circuit can be effectively reduced.
