Abstract
A pixel structure, a display panel, a display and a driving method thereof are disclosed. The pixel structure comprises an organic light emitting diode, a driving transistor, a storage capacitance, and a switch transistor. A first terminal of the driving transistor receives an image retention cancellation signal. The image retention cancellation signal changes to a second level from a first level before the driving transistor drives the organic light emitting diode so that the driving transistor is operated in a forward curve. A second terminal of the driving transistor is coupled to the light emitting diode. One terminal of the storage capacitance receives a common voltage, and the other terminal of the storage capacitance is coupled to a control terminal of the driving transistor. The switch transistor is controlled by a scan signal to output a data signal to the control terminal of the driving transistor.
