Abstract
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.
