OLED touch control drive circuit, method, and touch control panel
The present disclosure relates to a touch driving circuit. The touch driving circuit may include a driving transistor. A control terminal of the driving transistor is configured to receive a data signal. A first terminal of the driving transistor is configured to receive a power signal. A second terminal of the driving transistor is connected to a first electrode of a light emitting element in the touch panel. The touch driving circuit may include a touch electrode configured to transmit a touch signal. The touch electrode forms parasitic capacitance with a second electrode of the light emitting element. The touch driving circuit may include a control unit configured to transmit a compensation signal to the second terminal of the driving transistor in response to a control signal. The power signal, the data signal, the touch signal, and the compensation signal are synchronously modulated signals during a touch stage.
