Title:
PIXEL CHARGING METHOD, CIRCUIT, DISPLAY DEVICE AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/176917
Kind Code:
A1
Abstract:
A pixel charging method, a circuit, a display device and a computer storage medium, belonging to the technical field of displays. The method comprises: acquiring a grayscale value of each row of sub-pixels in any frame image of an image to be displayed (101); determining the charging duration of each row of sub-pixels according to the grayscale value of the each row of sub-pixels, the charging duration of the nth row of sub-pixels of the any frame image being positively correlated with the absolute value of a preset difference value, the preset difference value being the difference between the grayscale value of the nth row of sub-pixels and the grayscale value of the n-1th row of sub-pixels (102); and when the any frame image is displayed in a display panel, charging each row of sub-pixels according to the charging duration of the each row of sub-pixels (103). The charging duration of each row of sub-pixels is determined according to the grayscale value of the each row of sub-pixels so as to reduce the difference in charging rate between two rows of sub-pixels having a large difference in grayscale value. Thus, the present invention solves the problem in related technology wherein the charging rate of each row of sub-pixels may be uneven. The present invention also achieves the effect of improving the uniformity of the charging rate for each row of sub-pixels of a display panel.
