Abstract
Provided are a display panel. When a bias adjustment control signal is an effective pulse signal, a bias adjustment module is on and provides a bias adjustment signal for a drive transistor. The data refresh rate of a first pixel circuit is a first frequency F1. The data refresh rate of a second pixel circuit is a second frequency F2. F1≠F2. A data refresh period of the first pixel circuit includes R1 image refresh frames. A data refresh period of the second pixel circuit includes R2 image refresh frames. The sum of time durations of effective pulses of the bias adjustment control signal is Ws1 in the data refresh period of the first pixel circuit. The sum of time durations of effective pulses of the bias adjustment control signal is Ws2 in the data refresh period of the second pixel circuit. Ws1/R1≠Ws2/R2.
