More Information
Summary:A liquid crystal display device includes a liquid crystal panel, a backlight device at least including LEDs arrayed at intervals and LED wiring portions connected to the LEDs such that the LEDs adjacent to one another have different connection targets, an image signal generation unit that generates an image signal related to the image, a panel control unit that displays the image on the liquid crystal panel based on the image signal generated in the image signal generation unit, and an LED control unit that energizes a relatively great amount of the LED wiring portions when the image based on the image signal sent from the image signal generation unit is a normal image, and selectively energizes a relatively small amount of the LED wiring portions when the image is a small image of which a display range is smaller than a display range of the normal image.
