摘要： The present disclosure relates to the field of display technology and, in particular, to a pixel charging method, a pixel charging circuit, a display device, and a display control method. The pixel charging method includes acquiring a state of a backlight source and adjusting a charging time of a sub-pixel corresponding to the backlight source according to the state of the backlight source. When the backlight source is in an on state, the charging time of the sub-pixel corresponding to the backlight source is a first charging time. When the backlight source is in an off state, the charging time of the sub-pixel corresponding to the backlight source is a second charging time, the second charging time being shorter than the first charging time.

摘要： A method for debugging the display panel includes: acquiring a target correction data table of the display panel in each of at least one color mode by debugging the display panel in each of the at least one color mode. Debugging the display panel in each of the at least one color mode includes: controlling the display panel to display a test picture in the color mode; acquiring an initial display parameter curve based on a display parameter of the test picture; determining a reference display parameter curve based on the initial display parameter curve and a standard display parameter curve; and determining the target correction data table based on the reference display parameter curve and the standard display parameter curve.

摘要： The present disclosure discloses a driving method and apparatus of a display panel. When the display panel is driven to display a (2k−1)th image, only display data, corresponding to pixels of one row group, in image data of a kth display frame of a plurality of display frames are transmitted to a driver chip in the display panel, and a data size transmitted may be reduced. When the display panel is driven to display a (2k)th image, display data, corresponding to pixels of another row group, in the image data of the kth display frame are transmitted to the driver chip in the display panel, and the data size transmitted may also be reduced.

摘要： The present disclosure discloses a driving method and apparatus of a display panel. When each of a plurality of obtained display frames is transmitted, only display data, corresponding to each pixel in one row group, in the display frame of image data is transmitted to a driving chip in the display panel, so that the driving chip in the display panel drives the display panel to display an image according to the received display data. Therefore, when a system on chip transmits each of the plurality of obtained display frames, only the display data, corresponding to each pixel in one row group, in the display frame of image data is transmitted to the driving chip in the display panel.
