Abstract:
1. A display panel driving apparatus configured to 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 not less than the gray scale of the first sub-frame, for a response in which (i) an input gray scale of a subsequent frame is greater than an input gray scale of a previous frame and (ii) 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 being set to be not more than a second threshold gray scale, regardless of input gray scale of the subsequent frame, wherein the first threshold gray scale is greater than the second threshold gray scale; and if a first input gray scale is less than the second threshold gray scale and the first threshold gray scale is less than a second input gray scale, (a) for a response in which the input gray scale of the previous frame is the second input gray scale and the input gray scale of the subsequent frame is the second input gray scale too, the gray scale of the first sub-frame in the subsequent frame is set to be greater than the second threshold gray scale (b) for a response in which the input gray scale of the previous frame is the first input gray scale and the input gray scale of the subsequent frame is the second input gray scale, the gray scale of the first sub-frame in the subsequent frame is set to be not more than the second threshold gray scale.
