Patent number: 8922604Abstract: An image display device (2) controls a backlight luminance on the basis of a plurality of areas corresponding to LEDs, which are defined by dividing an input image. To cause sides of each subscreen to coincide with sides of its corresponding area, a subscreen control section (10) included in the image display device (2) changes positions and sizes of subscreen input images Dv1 to Dv3 included in a multiscreen input image Dv, the positions and the sizes being determined by subscreen setting data Ds, which is setting information. As a result, the number of areas corresponding to each subscreen is reduced, so that the number of LEDs to be lit up is reduced without causing display failures, thereby achieving low power consumption.Type: GrantFiled: November 19, 2010Date of Patent: December 30, 2014Assignee: Sharp Kabushiki KaishaInventors: Tatsunori Nakamura, Shigeki Imai
