Patent ID: 8624936

Claim:
A display panel control device which supplies, to a display panel, a monochrome image inserted video signal in which a unit cycle period including a first gradation voltage value video part for providing video display according to a gradation value of a video signal and a second gradation voltage monochrome image part for providing monochrome display according to a gradation value of a monochrome image signal are repeated, and performs a display drive control for the display panel by monochrome image insertion drive which starts insertion of monochrome image display scanning at an arbitrary timing of video display scanning, the display panel control device, comprising: a first correction device for performing a first correction for correcting response delay from the monochrome display to the video display by correcting the gradation value of the video signal or the gradation value of a monochrome image signal of a current frame based on the gradation value of the video signal of the current frame; a second correction device for performing a second correction on one of the gradation value of the video signal of the current frame that is corrected by the first correction device and the gradation value of the monochrome image signal of the current frame based on the video signal of a previous frame and the video signal of the current frame in such a manner that time integrated value of luminance in the another unit frame cycle period where display is being changed becomes larger than time integrated value of the luminance in still another unit frame cycle period after display is being changed when the gradation value of the video signal changes from a given unit frame cycle period to another unit frame cycle period; and a monochrome image insertion drive control device for generating the monochrome image inserted video signal including the video part and the monochrome image part to which the first correction and the second correction are performed, and performing the display drive control by the monochrome image insertion drive performed on the display panel.
