Abstract
A pixel circuit includes a first driving circuit, a first control circuit, a second driving circuit and a second control circuit. The first driving circuit is configured to write a first data signal into a first node in response to a scanning signal. The first control circuit is configured to transmit a first voltage signal to the first driving circuit, and transmit a first driving signal generated by the first driving circuit according to a voltage of the first node and the first voltage signal in response to an enable signal. The second driving circuit is configured to write a second data signal into a second node in response to the scanning signal. The second control circuit is configured to transmit a second driving signal generated by the second driving circuit according to a voltage of the second node and the first voltage signal in response to a control signal.
