Abstract: A compensation method of a display panel includes controlling a first display part of a target panel to display a light load image based on a standard gamma curve, controlling a second display part of the target panel to display a heavy load image, acquiring a first brightness of a first color sub-pixels in an (N1+1)th row electrically connected to a first data line of the first display part, acquiring a second brightness of the first color sub-pixels in an (N2+1)th row of a first sub-display part of the second display part electrically connected to a second data line, and according to a difference between the first brightness and the second brightness, determining a first compensation data corresponding to the first gray scale and the second preset gray scale of at least the first color sub-pixels of the first sub-display part in the target panel.

Abstract: The present application provides a splicing display, a driving method, and a splicing display device. The splicing display includes first sub-display panels and second sub-display panels. A size and a number of the first sub-display panels are respectively same as a size and a number of the second sub-display panels in horizontal or vertical directions. The first sub-display panel and the second sub-display panel are misaligned by N rows/columns of sub-pixels in the horizontal or vertical directions. Misaligning N rows/columns of the sub-pixels can increase an accuracy of the splicing display, and splicing positions can be prevented from problems of misalignment and blurring.

Abstract: A overvoltage compensation method for a display panel includes determining a corresponding compensation voltage value according to grayscale values of two adjacent pixels in a same column in a same frame or grayscale values of a same pixel in two adjacent frames, and an 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 integers include 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.

Abstract: A method and apparatus for driving a tiled display, a server, and a storage medium are provided. The spliced display comprises a first sub-display screen and a second sub-display screen, wherein a filling screen is arranged between the first sub-display screen and the second sub-display screen. By the method, the pictures on the sub-display screens are displayed on the filling screen, and images do not need to be spliced after being displayed on the filling screen and the sub-display screens, so as to improve the accuracy of the images at the filling screen and avoid image dislocation.

Abstract: A splice screen driving method, a splice screen driving device, an electronic device, and computer-readable medium are provided. According to a size of a filling screen in a splice screen, an initial video signal is expanded to obtain a first video signal that drives the filling screen. The second video signal corresponding to the filling screen in the first video signal is sharpened and filtered to improve a clarity of a picture at a connection of a sub-display and the filling screen, to solve a problem of picture blur.
