    摘要： An object of at least one embodiment of the present invention is to provide a liquid crystal display device and a driving method thereof, in which a contour of an image is clearly recognized during movie display even in a case where a backlight is turned on and off so as to change intervals at which the backlight turns on. In at least one embodiment, the liquid crystal display device includes a liquid crystal panel and the backlight that irradiates the liquid crystal panel with light, one frame period including a turn-on period during which the backlight turns on and a turn-off period during which the backlight turns off, luminance being changed by changing turn-on intervals of the backlight, the turn-on intervals of the backlight being changed by changing lengths of the turn-on period and the turn-off period. The liquid crystal display device further includes an OS process circuit for controlling a drive voltage to be applied to the liquid crystal panel by setting an amplitude of the drive voltage to be applied to the liquid crystal panel during a gray scale transition. The OS process circuit sets the amplitude of the drive voltage to be applied to the liquid crystal panel during the gray scale transition so as to be greater as the turn-on period of the backlight is longer under a condition where gray scales that have not been subjected to a gray scale transition is equal to gray scales that have been subjected to the gray scale transition in a case where the turn-on period of the backlight varies.

    摘要： An object is to moderate the occurrence of mura in an oblique view in an image display device that conducts area active driving. An emission luminance calculator (151) computes a luminance (first emission luminance) (32) of LEDs in respective areas on the basis of an input image (31). The emission luminance corrector (152) applies a correction to the first emission luminance (32) on the basis of correction data (33) in an LED filter (155). Herein, provided that a first image is defined as an image displayed in the case of being externally given an image in which a high-gradation region and a low-gradation region neighbor each other as the input image (31), the emission luminance corrector (152) uses the LED filter (155) to compute a second emission luminance (34), thereby setting the values of correction data (33) stored in the LED filter (155) so as to yield a constant degree of spatial variation in the output gradations between the high-gradation region and the low-gradation region in the case of viewing the first image from a designated oblique direction.

    摘要： A display method of an embodiment (i) determines a suitable length of an off period of an LED in accordance with a gray scale transition time, i.e., a time during which a transmittance of a liquid crystal is being changed, and (ii) turns off a light source for the determined length of the off period in a first half part of a one frame period. This makes it difficult for a halfway change in a gray scale transition to be reflected in a brightness of a pixel. Also, by performing a gray scale transition emphasis process to a display signal when the gray scale transition is caused, it is possible to increase the brightness of the pixel in the midst of the gray scale transition and to reduce a response time of the pixel. As such, it is possible to further improve a quality of moving image display.
