Kind Code:
B2
Abstract:
In one embodiment, a display panel driving apparatus which generates, based on an input gray scale, a gray scale of a first sub-frame and a gray scale of a second sub-frame so as to display the input gray scale as a result of a summation of respective display corresponding to the first sub-frame and the second sub-frame into which one frame is divided, and the gray scale of the second sub-frame being greater than the gray scale of the first sub-frame, for a response in which the input gray scale of a subsequent frame is greater than an input gray scale of a previous frame and the input gray scale of the subsequent frame is not less than a first threshold gray scale, a gray scale of the first sub-frame in the subsequent frame is set not more than a second threshold gray scale, regardless of input gray scale of the subsequent frame. Thus, it is possible to reduce jaggy in an edge of a moving image in time-division driving.
