Pixel circuit and method for controlling the same, and display device

A pixel circuit, comprising:

• an input circuit configured to output a driving signal to an element to be driven, so that the element to be driven emits light;
• and
• a time control circuit coupled to the input circuit and configured to control a light-emitting duration of the element to be driven in a light-emitting phase of a frame period to be a first duration by controlling the input circuit in response to a first control signal provided by a first control signal terminal, and control the light-emitting duration of the element to be driven in a light-emitting phase of another frame period to be a second duration by controlling the input circuit in response to at least a second control signal provided by a second control signal terminal and a third control signal provided by a third control signal terminal;
• wherein the second duration is less than the first duration, and the second duration includes a plurality of interval time periods;
• a frequency of the third control signal is multiple times a frequency of the first control signal, and is multiple times a frequency of the second control signal.
