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 application provides a display device and a display charging method. The display device includes a timing controller and a gate driving circuit. By increasing a voltage difference between the first potential and the second potential of a scan signal, a falling edge of the scan signal can be made more vertical, and by adjusting a phase of the scan signal in a timing at the same time, a pulse duration of the scan signal can be overlaid to a pulse duration of more data signals, so that the effective charging time of the data signals can be increased.
