Abstract
A driving controller includes an image analyzer, a grayscale setter and a time-and-space arranger. The image analyzer analyzes input image data to determine a peak luminance. The grayscale setter receives a gamma value and the peak luminance and to determine a boundary grayscale value and a minimum grayscale value. The time-and-space arranger is configured to temporally and spatially arrange first data having the boundary grayscale value and second data having the minimum grayscale value. The driving controller is configured to drive a display panel using the first data and the second data for a low grayscale range of which a grayscale is equal to or less than the boundary grayscale value and to drive the display panel based on a data signal corresponding to a grayscale value of the input image data for a normal grayscale range of which a grayscale is greater than the boundary grayscale value.
