Abstract
A pixel circuit and a display panel are provided. The pixel circuit includes a driving transistor Tand a pulse width driving module. The pulse width driving module includes a display time control unit, an electrical potential modulation unit, and a Schmitt trigger. By connecting the Schmitt trigger in series between an output terminal of the electrical potential modulation unit and a control terminal of the display time control unit, the driving transistor Tcan be turned off more quickly, thereby accurately controlling the display time or light-emitting time of the pixel circuit.
