Abstract:
The present disclosure provides a pixel circuit with pulse width compensation, and the pixel circuit includes a pulse width modulation circuit and a pulse amplitude modulation circuit, and the pulse amplitude modulation circuit is electrically connected to the pulse width modulation circuit. The pulse width modulation circuit includes a P-type pulse width compensation transistor and a first P-type control transistor, and the first P-type control transistor is electrically connected to the P-type pulse width compensation transistor. The pulse amplitude modulation circuit includes a second P-type control transistor, a first capacitor, a P-type driving transistor and a light-emitting element. The second P-type control transistor is electrically connected to the first P-type control transistor. The first capacitor is electrically connected to the second P-type control transistor. The P-type driving transistor is electrically connected to the first capacitor, and the light-emitting element is electrically connected to the P-type driving transistor.
