Patent ID: 8872733

Claim:
A liquid crystal display device for use in a multi-display device made up of a plurality of liquid crystal display devices set in array, said liquid crystal display device comprising: a display panel for displaying an image; a backlight device which is provided in back of the display panel and is divided into segments having respective light sources, the backlight device being capable of illuminating at light intensity adjustable for each of the segments; a receiving section for receiving image data indicative of an image to be displayed on the display panel; a light intensity determining section for determining a light intensity at which the backlight device illuminates for each of the segments of the backlight device; and a detecting section for detecting whether or not the receiving section has received the peripheral display image data, in a case where the receiving section receives peripheral display image data, the light intensity determining section determining the light intensity of each of the segments based on the image data and the peripheral display image data, the peripheral display image data being indicative of an image, which (i) is contiguous to the image to be displayed on the display panel and (ii) is to be displayed on at least part of a display panel of another liquid crystal display device provided around said liquid crystal display device among the plurality of liquid crystal display devices for use in the multi-display device, and in a case where the detecting section determines that the receiving section has not received the peripheral display image data, the light intensity determining section determining the light intensity of each of the segments such that (i) a lowest one of light intensities of all the segments does not become zero or (ii) a lowest one of light intensities of some of the segments in the vicinity of a bezel does not become zero, the bezel being a border between said liquid crystal display device and another liquid crystal display device provided around said liquid crystal display device among the plurality of liquid crystal display devices for use in the multi-display device.
