In one embodiment of the present invention, a display device is provided, the display device comprising: a body including a display module that outputs images; one or more lights positioned behind the body; and a control unit, wherein the control unit determines whether the display module is in operation and identifies the shape of the display module.

Bendable display device having ambient lights and method for controlling the same

The present disclosure relates to an image display apparatus. The image display apparatus according to an embodiment of the present disclosure includes a display panel; a plurality of light sources configured to output light to the display panel; a plurality of switching elements configured to switch the light sources, respectively; and a processor configured to output a switching control signal having variable amplitude to the switching element, wherein the processor controls a driving frequency of the light source to be a second frequency higher than a first frequency corresponding to a vertical synchronization signal of the panel. Thus, the sharpness of the image can be improved.

Image display device

Provided are a display device and an operating method thereof. The display device includes a liquid crystal display panel, a backlight unit including a plurality of light sources for supplying light to the liquid crystal display panel and driven in a state of being divided into a plurality of blocks corresponding to the number of the light sources, and a backlight dimming controller configured to calculate dimming values of the plurality of blocks. The backlight dimming controller is configured to divide each of the plurality of blocks into a plurality of unit blocks and control brightness of an output image differently for each of the unit blocks.

Display device and method of performing local dimming thereof

An image display apparatus is disclosed. The image display apparatus includes a panel configured to display an image, a backlight including a plurality of light sources configured to output light to the panel, a light source driver configured to drive the plurality of light sources, and a processor configured to control the light source driver, wherein the processor changes the turn on duty of a light source corresponding to a moving object area in an input image and changes the level of current flowing in the light source. Consequently, the definition and luminance of an image including a moving object may be improved.
