    Abstract: The present application discloses a pixel driving circuit with touch-sensing function. The driving circuit includes a first drive-control sub-circuit, a display-drive sub-circuit, a second drive-control sub-circuit, and an emission-control sub-circuit connected in series to generate a drive-current to drive a light-emission device in the subpixel under control of an emission-control signal in a respective one of multiple emission duty periods of a cycle time for displaying one frame of image. The drive circuit also includes a data-input sub-circuit and a charge sub-circuit to set a first voltage to the control terminal of the display-drive sub-circuit. Additionally, the drive circuit includes a photo-sensing sub-circuit configured to reset a photo-sensing device integrated with the light-emission device in the subpixel for touch sensing in a touch-sensing period before entering any one of the multiple emission duty periods of the cycle time.
