Abstract
The present application provides a display panel and a display device. The display panel includes a plurality of sub-pixels. Each sub-pixel includes a light-emitting unit and a drive switch electrically connected to a first electrode of the light-emitting unit. The light-emitting units in the multiple sub-pixels form a pixel array. Multiple light-emitting units in at least one pixel column of the pixel array correspond to sub-pixels of at least two colors. The drive switches in the multiple sub-pixels form a drive array. In the drive array, in drive columns correspondingly connected to the at least one pixel column, multiple drive switches in at least one drive column drive-control light-emitting units of the same color. Thus, the corresponding drive column can be connected to a peripheral drive circuit by using only one switch element.
