Abstract
The present disclosure provides a pixel circuit, its driving method, an organic light-emitting diode (OLED) display panel, and a display device. According to the present disclosure, a display driving module and a touch detection module are configured to multiplex a first scanning line and a second scanning line, so it is able to eliminate an effect of a threshold voltage of a driving transistor on a light-emitting driving signal, thereby to improve the brightness evenness of the OLED display panel and improve a display effect of the display device. In addition, the pixel circuit in the embodiments of the present disclosure may achieve the touch detection and the display driving simultaneously by multiplexing a control signal, so it is able to achieve the integration of the display driving and the touch detection in an effective manner.
