摘要： The present disclosure provides a display control method and a display control device. The display control method is used for a display panel. The display panel includes at least a first display area and a second display area arranged in a first direction, the first display area is coupled to a first signal line, and the second display area is coupled to a second signal line. The display control method includes: controlling a first sub-pixel in the first display area to display an image via the first signal line; and controlling a second sub-pixel in the second display area to display an image via the second signal line. A light-emission phase of the first sub-pixel at most partially overlaps a light-emission phase of the second sub-pixel.
