1. A pixel circuit, comprising:
a driving circuit coupled to at least a data signal terminal, a scan signal terminal, a first voltage terminal and a first enable signal terminal, the driving circuit being configured to: receive a data signal received at the data signal terminal, in response to a scan signal received at the scan signal terminal; and generate, in response to a first enable signal received at the first enable signal terminal, a driving signal according to a first voltage at the first voltage terminal and the data signal;
a first control circuit coupled to at least a second enable signal terminal, a first control signal terminal, a first input signal terminal, a second control signal terminal, a second input signal terminal and a third input signal terminal, the first control circuit being configured to: receive a first input signal received at the first input signal terminal in response to a first control signal received at the first control signal terminal, and transmit a third input signal received at the third input signal terminal in response to the first input signal; and receive a second input signal received at the second input signal terminal in response to a second control signal received at the second control signal terminal, and transmit a second enable signal received at the second enable signal terminal in response to the second input signal; and
a second control circuit coupled to the driving circuit and the first control circuit, and configured to be coupled to an element to be driven, the second control circuit being further configured to receive one of the third input signal and the second enable signal, and transmit the driving signal from the driving circuit to the element to be driven in response to the one of the third input signal and the second enable signal, so as to control an operating duration of the element to be driven.
