  • Drive method and drive circuit for driving organic light-emitting diode panel and display device
    Patent number: 10963081
    Abstract: Provided are a drive method and drive circuit for an organic light-emitting diode panel and a display device. The method is applied to an organic light-emitting diode panel, which includes a light-emitting layer, and a first light-emitting control electrode layer and a touch electrode layer sequentially on the light-emitting layer. The first light-emitting control electrode layer and the touch electrode layer are insulated from each other. The method includes: outputting a display voltage to the first light-emitting control electrode layer at a display stage and outputting a shielding voltage to the first light-emitting control electrode layer at a touch stage.
    Type: Grant

  • Conversion circuit, display panel and display device
    Patent number: 10796657
    Abstract: Provided is a conversion circuit, including a switch signal input terminal; first and second input terminals; and first and second output terminals. The switch signal input terminal receives a switch control signal. The first and second input terminals receive first and second input signals, and polarities of first and second input signals are different and alternately switch. Depending on the switch control signal, the first input terminal is in communication with the first output terminal and the second input terminal is in communication with the second output terminal, or the second input terminal is in communication with the first output terminal and the first input terminal is in communication with the second output terminal, so that a first output signal outputted from first output terminal has a consistent polarity at any time and a second output signal outputted from the second output terminal has a consistent polarity at any time.
