Claim One:
1. A display device, comprising: a display panel configured to display an image including a logo region; and a display driving integrated circuit configured to drive the display panel, wherein the display driving integrated circuit is further configured to: detect a logo estimate region of the image that surrounds the logo region of the image; determine a logo surrounding region of the image that surrounds the logo estimate region of the image; analyze a histogram of the logo surrounding region of the image so as to determine a background maximum luminance of the logo surrounding region of the image; determine a high-gray-scale maximum luminance of the logo estimate region of the image based at least in part on the background maximum luminance of the logo surrounding region of the image; and adjust a gamma curve of the logo estimate region of the image to control luminance of an entire gray-scale range of the gamma curve of the logo estimate region of the image so as to be less than the high-gray-scale maximum luminance of the logo estimate region of the image.
