摘要

To provide a display panel control device capable of preventing generation of step-like tailing and ghost when executing black insertion drive. A first correction device performs first correction on a gradation value of a video signal by considering response delay of the display panel when changing from a second gradation voltage to a first gradation voltage. A second correction device performs second correction on one of or both of the gradation value of the video signal and the gradation voltage of a monochrome image signal by considering accumulative luminance reaching delay of the video part caused due to a difference between each monochrome display luminance of each monochrome image part in different unit frame cycle periods, when the gradation value of the video signal changes from a unit frame cycle period to another unit frame cycle period. A monochrome image insertion drive control device generates the monochrome image inserted video signal including the video part and the monochrome image part to which the first correction or the second correction is performed, and controls the monochrome image insertion drive of the display panel.
