Abstract: Periods P1 to P3 are set when a power of a liquid crystal display device 10 is turned off. In an afterimage deletion period P1, a gate line is driven similarly to a case of a normal operation, and a correction voltage obtained by adding a pull-in voltage to a voltage of a common electrode is applied to a source line. In a voltage drop period P2, a zero voltage is applied to the gate line, the source line, and the common electrode. In a charge discharging period P3, the zero voltage is applied to the source line and the common electrode, and in at least a part of the charge discharging period P3, a voltage that enables charge to move between the source line and the pixel electrode via a TFT is applied to the gate line. A voltage holding unit that, even after an input power voltage is reduced, supplies a voltage, which is almost equal to the input power voltage, until at least the period P3 ends is provided. As a result, flicker or image sticking caused when the power is turned on again is prevented.

Abstract: A display device (10) includes a display panel (11), a backlight (12) having a switchable light emission color, a display control circuit (15), and a finish signal output unit (16). The finish signal output unit (16) outputs a finish signal (C1) for instructing turn off of the backlight (12) at an arbitrary timing. The display control circuit (15) divides one frame period into a plurality of subfield periods, and outputs backlight data (D1) and a video signal (V2) including subfield data in each subfield period. When detecting the finish signal (C1), the display control circuit (15) turns off the backlight (12) after controlling the display panel (11) and the backlight (12) so that an achromatic color subfield is displayed. With this, unnatural display when turning off the backlight can be prevented.

Abstract: In a display control circuit (200) of a display device, an image pattern detection portion (230) detects whether an image is an anti-flicker pattern or not, and when it is an anti-flicker pattern, a backlight source is driven (typically, such that its luminance changes in the opposite phase relative to luminance changes that would occur), on the basis of predicted values, which are predetermined so as to compensate for the luminance changes that would occur. Moreover, the backlight is not turned on during the scanning period. As a result, flicker due to current leakage, etc., can be reduced or eliminated in a display device for which a scanning period and a scan stop period are set.
