  • Display panel and display device
    Patent number: 11881132
    Abstract: A display panel and a display device. The display panel includes a test circuit located in a non-display region. The test circuit includes a plurality of switching transistors and at least one data switching line extending in a first direction. In each switching transistor, a first end of the switching transistor is electrically connected to a data line in the display panel, and a second end of the switching transistor is configured to receive a test data signal. The data switching line is disposed in the same layer as a source-drain layer of the switching transistor. The data switching line is configured to control the switching transistor to be turned on or off.
    Type: Grant

  • Touch display panel and touch display device
    Patent number: 11287936
    Abstract: The disclosure discloses a touch display panel and a touch display device. The touch display panel includes a cathode and a number of touch electrodes, wherein an interior of at least one touch electrode is hollowed out to reduce a relative area between the cathode and the touch electrode. The relative area between the touch electrode and the cathode of the touch display panel may be reduced by hollowing out the interior of at least one touch electrode, thereby reducing the inductive capacitance between the touch electrode and the cathode.
