Abstract

The present disclosure relates to a pixel circuit. The pixel circuit may include at least one light emitting circuit. One of the at least one light emitting circuit may include an input sub-circuit, a latch sub-circuit, and an output sub-circuit. The input sub-circuit may be configured to transmit a signal at a data voltage terminal to the latch sub-circuit. The latch sub-circuit may be configured to generate a control signal in accordance with the signal at the data voltage terminal and store the control signal. The output sub-circuit may be configured to transmit one of a signal at a first voltage terminal and a signal at a second voltage terminal to a light emitting unit under control of the control signal.
