Abstract: A display panel and a display apparatus are provided. The display panel includes a display area. The display area includes color pixels and pixel groups. The color pixels include a first pixel, a second pixel and a third pixel that have different colors from one another, each of the pixel groups includes one first pixel, one second pixel, one third pixel and at least one color-changing pixel. An operating state of the at least one color-changing pixel includes a transparent state and a black state. The display panel provided by the present disclosure can achieve a transparent display effect, and can also display black pixel information in an image by using a black state of the color-changing pixel, which solves the technical problem in the related art in which transparent display is difficult to display black pixel information in the image.

Abstract: A driving method includes driving a display panel at a first-frequency driving mode and a second-frequency driving mode. A first frequency of the first-frequency driving mode is lower than a second frequency of the second-frequency driving mode. In the first-frequency driving mode, a frame time includes a scanning section and a corresponding front and rear porch section immediately following the scanning section. The driving method further includes scanning sub-pixels of the display panel in the scanning section of the first-frequency driving mode, where in the front and rear porch section, the sub-pixels of the display panel are not scanned, and front and rear porch sections corresponding to at least part of a plurality of frames in the first-frequency driving mode include at least one compensation section. The method further includes providing a data signal to each data line of a plurality of data lines of the display panel in a compensation section of the at least one compensation section.
