Category (FI): F21V23/00,117,H05B47/105,H05B45/18,H05B47/16,G02F1/133,535,G09G3/20,670@L,G09G3/20,612@R,G09G3/20,642@Z,G09G3/34@J,G09G3/36,G02F1/133,580
Stage: PROBLEM TO BE SOLVED: To provide a control device and a liquid crystal display device capable of quickly increasing luminance of light emitted by a backlight when a bright image is inputted after a dark image is inputted.SOLUTION: A control device controls a backlight provided in a display device, and includes an acquisition portion for acquiring input luminance from an image signal, and a control portion that performs first control for setting output luminance of light emitted from the backlight to the input luminance, performs second control for setting the output luminance to a second threshold or less that is smaller than the first threshold when a state in which the output luminance is equal to or more than the first threshold for a set time or longer continues, and ends the second control in the middle and performs the first control when the input luminance becomes the second threshold or less during the second control.SELECTED DRAWING: Figure 1 (Grant)
