    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; 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.

    IPC: G09G3/36

    Abstract: A data signal delay circuit and delay method and a display device are disclosed. The data signal delay circuit includes a feedback signal generation sub-circuit, a compensation signal generation sub-circuit, and a control sub-circuit. The feedback signal generation sub-circuit is configured to generate a feedback signal based on a first level signal from the first level signal terminal and a second level signal from the second level signal terminal under the control of a gate drive signal from a scan signal line currently being scanned. The compensation signal generation sub-circuit is configured to generate a compensation signal based on the feedback signal and a data enable signal from the data enable signal line. The control sub-circuit is configured to delay a data enable signal of the data enable signal line in a next cycle based on the compensation signal.
