  • Patent number: 10275101
    Abstract: An integrated touch control display panel and a display apparatus are disclosed. The integrated touch control display panel comprises a touch-control-emitting-electrode-array including a plurality of touch control emitting strip electrodes arranged along a first direction; and a touch-control-sensing-electrode-array including a plurality of touch control sensing strip electrodes arranged along a second direction. An orthogonal projection of any touch control sensing strip electrode to the touch-control-emitting-electrode-array at least partially overlaps with any of the touch control emitting strip electrodes; and the touch control sensing strip electrodes are metal mesh electrodes, the metal mesh electrodes comprising a plurality of metal curves. This can reduce the resistance of the touch control sensing strip electrode, such that the integrated touch control display panel and the display apparatus have a more sensitive touch control sensing effect.

  • Patent number: 10262618
    Abstract: A GOA circuit includes GOA circuit units. Each GOA circuit has a holding module A first transistor and a second transistor in the holding module holds the voltage imposed on the first control node to be at high voltage level. Also, the transistors form a direct current passage between the first control node and a first fixed voltage at high voltage level so the voltage imposed on the first control node is not lowered due to electricity leakage. The GOA circuit unit can resolve the problem of easy leakage of electricity. When the scanning signals are output by the GOA circuit unit, the stability is highly ensured.
