Abstract
A pixel circuit and a display panel are disclosed. The pixel circuit comprises a first transistor, a pulse amplitude driving module, and a pulse width driving module. The pixel circuit and the display panel utilize a pulse amplitude driving module to drive the first transistor when a middle to high gray value of a frame is being displayed such that the number of frequency divisions in a high gray value could be reduced. Furthermore, the pixel circuit and the display panel utilize a pulse width driving module to drive the first transistor when a middle to low gray value of the frame is being displayed to improve the light emitting efficiency and luminance evenness in a low gray value.
