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.

Abstract: The present application provides a display device, a display panel and a capacitance compensation method thereof. A standard for performing a capacitance compensation on row scan lines in a first display region having fewer pixel units is that total load capacitance of a row scan line of a row adjacent to a second display region is equal to self-load capacitance of a row scan line of any row in the second display region, and that total load capacitance of each of the row scan lines decreases smoothly from the row adjacent to the second display region to a row away from the second display region.
