Abstract

Provided is a display panel and display device. The display panel includes a first type sub-pixel and a second type sub-pixel. The first type sub-pixel includes a first voltage-regulating module, which is connected between a pixel drive circuit and a light-emitting component in the first type sub-pixel for increasing a voltage of two ends of the light-emitting component; and/or, the second type sub-pixel includes a second voltage-regulating module, which is connected between a pixel drive circuit and a light-emitting component in the second type sub-pixel for reducing a voltage between a first end and a second end of the light-emitting component.
