20080246779 | DRIVING APPARATUS OF DISPLAY DEVICE, DISPLAY DEVICE INCLUDING THE SAME, AND METHOD OF DRIVING DISPLAY DEVICE - The driving apparatus of a display device calculates a slope using a minimum gray, a maximum gray, a gray average of frame data in a current frame, and a gray average of frame data in a previous frame, and corrects and outputs the input frame data according to the slope, using frame data of one frame. As a result, a gray range of the input image signal can be extended, thereby improving visibility. Further, in a case of a motion picture, even when a difference of a gray range of images of adjacent frames is large, an original image is not distorted due to extension of a gray range. Also, even when noise is included in the input image signal, a gray range can be extended after removing the noise. | 10-09-2008 |
