Abstract: A pixel circuit includes an input circuit and a time control circuit. The input circuit is configured to output a driving signal to an element to be driven. The time control circuit is configured to control a light-emitting duration of the element in a light-emitting phase to be a first duration by controlling the input circuit coupled thereto in response to a first control signal from a first control signal terminal, and control the light-emitting duration in another light-emitting phase to be a second duration by controlling the input circuit in response to a second control signal from a second control signal terminal and a third control signal from a third control signal terminal. The second duration is less than the first duration. The second duration includes interval time periods. The third control signal has a frequency multiple times that of the first control signal or the second control signal.
