Abstract
To provide a display panel control device capable of improving gap of moving pictures, etc., without increasing the dividing number of the backlight. The device includes: a black image insertion driving part which performs, on a display panel, black image insertion drive in which video display scanning and black image display scanning are executed in a specific period; and a light-up timing control part which controls a light-up start timing and a light-off start timing of each light source block based on a synchronous signal which synchronizes with the start timing of the video display scanning or the black image display scanning. The light-off period of the light source block is equal to or less than a period from the end of black image display scanning performed on all display lines within a block area to the start of video scanning performed on the first display line within the area.
