Pixel circuit, pixel circuit driving method, and display device thereof
A pixel circuit includes a driving circuit, a lighting element, and multiple switching circuits. The driving circuit is configured to provide a driving current to a first node. A first terminal of the lighting element is coupled with a second node. A second terminal of the lighting element is configured to receive a system low voltage. The multiple switching circuits are coupled between the first node and the second node in a parallel connection, and configured to correspondingly receive multiple emission control signals and at least one grayscale control signal. During each frame, the multiple emission control signals provide multiple pulses, and the multiple pulses do not mutually overlapping in time sequence, so that the multiple switching circuits selectively couple the first node to the second node according to the multiple pulses and the at least one grayscale control signal.
