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.

Abstract: The present invention provides an overvoltage compensation method and device, a display panel, and a storage medium. The method comprises: determining a corresponding compensation voltage value according to grayscale values of two adjacent pixels in the same column in the same frame or grayscale values of the same pixel in two adjacent frames, and a overvoltage compensation table, wherein the overvoltage compensation table has a first grayscale value group and a second grayscale value group that both contain all integers in [0,2k), the integer includes a plurality of binding point values, and a difference between two adjacent binding point values of the first four binding point values is not greater than 2k−8 wherein k is an integer greater than 8; transmitting the compensation voltage value to the display panel to make the pixel present the second grayscale value.
