Abstract:
The present application discloses a pixel circuit for a light-emitting diode display panel. The pixel circuit includes a reset sub-circuit configured to initialize voltage levels of some nodes. Additionally, the pixel circuit includes a data-input and compensation sub-circuit configured to load a data signal and adjust the voltage levels of the nodes for determining a driving current flown through a driving sub-circuit. The pixel circuit further includes a voltage-control sub-circuit for controlling a switch sub-circuit to determine whether the driving current is flowing or not. Moreover, the pixel circuit includes an emission-control sub-circuit configured to control a partial time span in one scan for passing the driving current to the light-emitting diode to drive light emission. The one scan is one of multiple different scans in one cycle time of displaying one frame of image.
