Beschreibung
Zusammenfassung:	A pixel circuit is provided. The pixel circuit includes a light emitting diode, a pulse amplitude control block, a pulse width control block, and a reset block. The light emitting diode has an anode receiving a system high voltage, and a cathode. The pulse amplitude control block is coupled between the cathode of the light-emitting diode and a system low voltage, and receives a first reference voltage to control a driving current of the light-emitting diode based on the first reference voltage. The pulse width control block is coupled to the pulse amplitude control block, receives a data voltage, and controls the pulse amplitude control block based on the data voltage to determine a single providing time of the driving current. The reset block is coupled to the pulse amplitude control block to set a state of the pulse amplitude control block.
