Abstract
The present disclosure discloses a pixel circuit, an organic electroluminescent display panel and a display apparatus, and during a reset phase, under a control of a reset signal terminal (Rst), a touch detection unit and a light emitting control unit in the pixel circuit are reset respectively; during a touch read phase, under a control of a scanning signal terminal (Scan), the touch detection unit outputs a touch detection signal to a touch signal read terminal (Read), so as to implement a touch detection function, meanwhile the light emitting control unit is charged; and during a light emitting phase, under a control of a light emitting signal terminal (Em), the light emitting control unit drives a light emitting device to emit light, so as to implement a display driving function.
