Abstract

Provided are a display device and an image processing method thereof. In an embodiment, the display device includes a display panel including a plurality of pixels formed of red, green, blue, and white sub pixels, and an image processing unit for converting a three-color input image supplied to the red, green, blue, and white sub pixels into four-color image data and outputting an output image by applying a final gain calculated using a frame gain, a pixel gain, and a block gain of the pixels. The display device also includes a timing controller for outputting the output image from the image processing unit to the display panel. The block gain may be calculated using scaled versions of luminance values determined by converting a luminance of the three-color input image and position information of the pixels.
