Abstract:
A pixel circuit, a display panel and a control method are disclosed. The pixel circuit includes a light-emitting device, a driving module, and a light-emitting control module. By inserting the corresponding number of black frame insertion pulses into the light-emitting control signal during the early light-emitting stage and the late light-emitting stage of one frame, the difference between the sum of the light-emitting currents in the early light-emitting stage of said frame and the sum of the light-emitting currents in the late light-emitting stage of said frame can be reduced, and the perceived brightness difference in one frame can be effectively reduced, so as to improve the screen flickers.
