Abstract
The present application provides a display panel and a display device. Pulse width modulation modules of a plurality of sub-pixels included in the same sub-pixel group receive the same frequency sweep signal, and pulse width modulation modules and the pulse amplitude modulation modules of the plurality of sub-pixels included in the same sub-pixel group receive the same light emission control signal. The start time when pixel driving circuits of at least two of the sub-pixel groups provide flow paths for corresponding driving currents according to corresponding light emission control signals is different.
