Document Type and Number:
WIPO Patent Application WO/2016/068066
Kind Code:
A1
Abstract:
A display device (10) is provided with a backlight (1), a rear display panel (2), a front display panel (3), and an image processing unit (7). The image processing unit (7) corrects the pixel value of pixels in a region to be adjusted for a rear image signal and outputs the corrected pixel value to the rear display panel (2) on the basis of the rear image signal for an image to be displayed on the rear display panel (2), and a front image signal for an image to be displayed on the front display panel (3). The video image processing unit (7) corrects and outputs the pixel value of pixels in the region to be adjusted so that the sum of the light transmission quantity of pixels in the region to be adjusted on the rear display panel (2) and the light transmission quantity of corresponding pixels on the front display panel (3) located in positions corresponding to the pixels in the region to be adjusted is equal to a light transmission quantity represented by the pixel value of corresponding pixel for the front image signal.
