Display Panel Driving Apparatus, Display Apparatus, Display Panel Driving Method, and Television Receiver

A display panel driving apparatus which generates, based on an input gray scale, gray scales of first through n-th sub-frames so as to display the input gray scale as a result of a summation of respective display corresponding to the first through n-th sub-frames into which one frame is divided,

• the first through n-th sub-frames being divided into a first half section including at least the first sub-frame and a last half section including at least the n-th sub-frame, and each sub-frame of the last half section has a gray scale greater than that of each sub-frame of the first half section,
• 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 said each sub-frame of the first half section in the subsequent frame is set not more than a second threshold gray scale, regardless of input gray scale of the subsequent frame.

A method for driving a display panel, which method 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,

• said method comprising the step of:
• setting a gray scale of the first sub-frame in the subsequent frame not more than a second threshold gray scale regardless of input gray scale of the subsequent 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.
