Abstract: A display substrate includes a base, a middle frame below the base and a pressure sensor for sensing a touch operation to generate a touch signal. The pressure sensor includes multiple sensing units, each having a first electrode on the base that deforms in response to the sensed touch pressure; a second electrode between the middle frame and the base that forms a capacitor with the first electrode, the capacitance of the capacitor changing with the deformation of the first electrode; and a sensing circuit electrically connected to the first electrode for transforming changes in the capacitance into electrical signals so as to generate the touch signal.

Abstract: The present disclosure provides a pixel driving circuit, including a first pixel driving unit and a second pixel driving unit. The first pixel driving unit includes a first driving transistor, a first storage capacitor and a first driving control unit. The first driving control unit is configured to apply a jumping voltage onto the data voltage at a first compensation stage, so as to perform jumping compensation on a threshold voltage of the first driving transistor. The second pixel driving unit includes a second driving transistor, a second storage capacitor and a second driving control unit. The second driving control unit is configured to apply a jumping voltage onto the data voltage at a second compensation stage, so as to perform jumping compensation on a threshold voltage of the second driving transistor and control the second light-emitting element to emit light.
