    Abstract: A pixel-driving circuit includes a driving sub-circuit with at least one transistor and one capacitor coupled to a light-emitting device. The pixel-driving circuit further includes an initialization sub-circuit coupled to the light-emitting device and configured to initialize the light-emitting device with a initialization signal under control of a scan signal. Additionally, the pixel-driving circuit includes a data-input sub-circuit coupled to the driving sub-circuit and configured to write the data signal to the driving sub-circuit under control of a scan signal. Furthermore, the pixel-driving circuit includes an emission-control sub-circuit having two transistors of different types and one capacitor coupled to the driving sub-circuit and the light-emitting device and configured to control the driving sub-circuit to output a driving current based on the data signal under control of a control signal and a reference-voltage signal.

    Abstract: The present application provides a display panel, a method of driving the same and a display apparatus. The display panel has pixel regions, each of which has pixel structures. Each of the pixel structures includes an anode, a cathode and a light emitting layer. The display panel further includes a controller and power signal lines coupled to the controller. Cathodes or anodes in a same pixel region are coupled to a same power signal line. The controller is configured to control a duty cycle of a control signal input to a power signal line coupled to a pixel region in response to a motion picture being displayed in the pixel region.
