Abstract: The present disclosure is related to a pixel circuit. The pixel circuit may include a first transistor, a photoelectric sensor, a switch transistor, a second transistor, a third transistor, and a light-emitting component. The first transistor may be configured to transmit a data voltage in response to a scanning signal of an N-th row. The second transistor may be configured to generate a driving current based on a data voltage transmitted by the first transistor and to generate a leakage current based on an electric signal transmitted by the switching transistor. The third transistor may be configured to compensate a threshold voltage of the second transistor in response to a scanning signal of an N-th row. The light-emitting component may be configured to emit light under an action of a driving current generated by the second transistor.
