Abstract:
A method of operating display device includes initializing an image display reference coordinate as a random coordinate among coordinates included in a shift pattern when power is applied to the display device, shifting the image display reference coordinate from the random coordinate along the shift pattern, and displaying an input image to a display panel included in the display device based on the image display reference coordinate.
Abstract:
A display device and method of adjusting luminance of a logo region of an image displayed on the same are disclosed. In one aspect, the display device includes a display panel configured to display an image including a logo region and a display driving integrated circuit configured to detect a logo estimate region of the image and determine a logo surrounding region that surrounds the logo estimate region. The integrated circuit is further configured to analyze a histogram of the logo surrounding region so as to determine a background maximum luminance, determine a high-gray-scale maximum luminance of the logo estimate region based on the background maximum luminance and adjust a gamma curve of the logo estimate region.
Abstract:
A method of digital-driving an organic light emitting display device includes analyzing a light emission pattern of the input image data and converting a third grayscale of the input image data into a first converted grayscale and a second converted grayscale based on an analysis result of the light emission pattern of the input image data.
