Abstract: A display panel and a display device are disclosed. The display panel includes a plurality of scan lines, a plurality of data lines, and a plurality of sub-pixels. Each of the scan lines is electrically connected to a row of the sub-pixels. The plurality of sub-pixels include a first pixel column and a second pixel column. The first pixel column and the second pixel column are arranged adjacent to each other. The first pixel column includes a plurality of first pixel units. The second pixel column includes a plurality of second pixel units. Each of the first pixel unit and the second pixel unit includes three sub-pixels, and colors of the three sub-pixels are different. At least two adjacent first pixel units and at least two adjacent second pixel units are electrically connected to a same data line.

Abstract: The present disclosure provides display panels and compensation methods thereof, and devices for generating compensation grayscales. The compensation method includes: obtaining a first compensation grayscale of first subpixels included in a first display portion and a second compensation grayscale of second subpixels included in a second display portion corresponding to a first original grayscale, where the first compensation grayscale and the second compensation grayscale are respectively determined by a second brightness of the second subpixels and a first brightness of the first subpixels under the first original grayscale; and controlling a first part of the first subpixels and a first part of the second subpixels to emit light under the first original grayscale, controlling a second part of the first subpixels and a second part of the second subpixels to emit light respectively under the first compensation grayscale and the second compensation grayscale.

Abstract: The present application provides a display panel and a driving method thereof, electronic device, display panel includes data lines, a first sub-pixel and a second sub-pixel disposed adjacently and connected to a same one of the data lines. In a display stage of a first type frame, a second gate electrode driver unit connected to the second sub-pixel outputs a first effective scan signal to control the second sub-pixel to switch on and be loaded with a second data voltage to emit light, and a first gate electrode driver unit connected to the first sub-pixel controls the first sub-pixel to switch off.
