Pixel circuit

A pixel circuit is provided. The pixel circuit includes a light emitting diode, a first transistor, a pulse amplitude control block, a pulse width control block, a rapid raising block and a reset block. The pulse amplitude control block is coupled to a control terminal of the first transistor, and controls a driving current flowing through the first transistor based on a reference voltage. The pulse width control block provides a node voltage based on a data voltage and a sweep signal. The rapid raising block controls the pulse amplitude control block based on the node voltage to raise a rising speed of the driving current of the first transistor and determine a single providing time of the driving current. The reset block sets states of the pulse amplitude control block and the fast lift block based on a light-emitting control signal.
