Abstract

A pixel circuit and a display panel are provided in the present application. The pixel circuit includes a driving module, a pulse amplitude modulation module, a pulse width modulation module, an internal compensation module, and an electrical potential maintaining module. High grayscale display is controlled by the pulse amplitude modulation module in a pulse amplitude modulation manner, low grayscale display is controlled by the pulse width modulation module in a pulse width modulation manner, and the internal compensation module performs internal compensation on a first terminal of the driving module, to realize an internal compensation and hybrid driving of the pixel circuit.
