A display device includes: a display which includes a display screen on which a video is displayed; a decorative sheet disposed on a display screen side of the display, is larger than the display screen in a front view of the display screen, and covers the display screen, the decorative sheet including a first region which overlaps with the display screen in the front view and a second region which does not overlap with the display screen in the front view; and a controller which controls a luminance of the video that is displayed by the display, based on (i) an illuminance of ambient light around the display and the decorative sheet and (ii) first information indicating a relationship between the illuminance and appearances of a third region corresponding to a black display region of the video in the first region and the second region on the decorative sheet.

Display device and control method

An image display device includes: an image display unit which includes a display panel switchable between an image display mode in which an image is displayed and a transmissive mode in which the display panel is in a transmissive state where an object behind the image display unit is visible in a front view of the display panel; a controller which controls an operation of the display panel; and a lower shelf board which is a holding member. The lower shelf board is disposed projecting rearward from a rear surface of the image display unit and holds the controller in a housed state.

Image display device

An image display device includes an image display unit including a display panel, a shelf board, and an illumination unit. The display panel is switchable between an image display mode in which an image is displayed and a transmissive mode in which the display panel is in a transmissive state where objects behind image display unit is visible in a front view of the display panel. The shelf board is disposed projecting rearward from the rear surface of image display unit, and extends in the lateral direction. The illumination unit is disposed above the shelf board and emits light downward.

A display apparatus including: a liquid crystal panel for displaying left and right images; a liquid crystal driver for writing an image signal into the liquid crystal panel; a backlight source for radiating light to the liquid crystal panel; and a controller for controlling the backlight source so that it emits the light during first emission periods which are set for a left viewing periods while a left image is viewed with a left eye and right viewing periods while a right image is viewed with a right eye, respectively, wherein the controller controls the backlight source so that it emits the light during a second emission period within a non-viewing period, during which no image is viewed, and sets a turn-off period during which the backlight source is turned off between the first and second emission periods.
