Abstract
There are provided a pixel charging method, a circuit, a display device and a computer storage medium. The method includes: acquiring a gray-scale value of each row of sub-pixels in an image frame of an image to be displayed; determining a charging time of each row of the sub-pixels according to the gray-scale value thereof; and charging each row of the sub-pixels according to the charging time thereof when a display panel displays the image frame. The charging time of each row of sub-pixels is determined according to the gray-scale value of each row of the sub-pixels, so as to reduce a charging rate difference between two rows of sub-pixels which have a relatively larger gray-scale value difference therebetween, and achieve an effect of improving the uniformity of the charging rates of all rows of sub-pixels in the display panel.
