Patent ID: 8026934

Claim:
A driving control apparatus of a display apparatus which displays an image by time-dividing one frame of an input image signal into first to n-th (n is an integer not less than 2) sub frames, the driving control apparatus comprising: signal generation means for generating first to n-th display signals for the first to n-th sub frames, respectively, in such a way that a total sum of brightness of a display screen of a display module in one frame is not changed by a division of the frame; and signal correction means for generating a corrected display signal in such a way that, to improve a response speed of a pixel in which a grayscale level of a first display signal of an N-th frame (N is an integer not less than 2), the first display signal being generated by the signal generation means, is changed for more than a predetermined value with respect to a grayscale level of an input image signal of an (N-1)-th frame, the grayscale of the first display signal for the pixel is corrected, the signal generation means for (i) adjusting the grayscale level of the first display signal within a range from a minimum value to a second predetermined value which is smaller than a maximum value and setting grayscale levels of the second to n-th display signals to be a value which is identical with the minimum value when an image having low brightness is displayed, and (ii) setting the grayscale level of the first display signal at the second predetermined value and adjusting the grayscale levels of the second to n-th display signals within a range from the minimum value to the maximum value, when an image having high brightness is displayed, and the signal correction means correcting the grayscale level of the first display signal within a range from the minimum value to the maximum value, but not correcting the grayscale levels of the second to n-th display signals.
