Abstract
Provided are a display panel and a display device. The display panel includes a first display region, a second display region, and a transition display region between the first display region and the second display region. The second display region includes second pixel units, the transition display region includes third pixel units, and each second pixel unit and each third pixel unit both include a first sub-pixel, a second sub-pixel, a third sub-pixel, and a white sub-pixel. A ratio of a total opening area of white sub-pixels in the second pixel units to a total area of the second pixel units is A, and a ratio of a total opening area of white sub-pixels in the third pixel units to a total area of the third pixel units is B, where B<A. The white sub-pixel is turned on or off in a display stage of the display panel.
