摘要： In one embodiment of the present invention, to time-divide one frame of an input image signal into a first-half sub frame and a second-half sub frame, the grayscale of the signal in the second-half sub frame is set at a grayscale for dark display and the grayscale of the display signal of the first-half sub frame is adjusted, when the input image signal indicates low brightness. When an image with high brightness is displayed, the grayscale of the display signal of the first-half sub frame is set at a second predetermined value smaller than the maximum value and the grayscale of the display signal of the second-half sub frame is adjusted. Thereafter, in accordance with a combination of the input image signals of the (N-1)-th frame and the N-th frame, overshoot is performed with respect to the display signal of the first-half sub frame.

摘要： A modulation processing section compares video data of a current frame and a previous frame representative value supplied from a frame memory, corrects the video data so that a gradation transition from a gradation indicated by the previous frame representative value to a gradation indicated by the video data is emphasized, and outputs the corrected video data. A judgment section compares both of the data and judges, out of a value calculated from the previous frame representative value by a representative value generating section and the video data, which is to be stored in the frame memory till a next frame begins. This allows for realizing a liquid crystal display device capable of preventing with a relatively small-scale circuit (alternatively, a relatively small amount of calculation) a phenomenon such that: although a response speed of a pixel is improved, the emphasis modulation and a response delay of the pixel are combined so that image quality in displaying moving images deteriorates.

Thereafter, in accordance with a combination of the input image signals of the (N−1)-th frame and the N-th frame, overshoot is performed with respect to the display signal of the first-half sub frame, in such a way as to restrain the decrease in the moving image quality on account of an insufficient response of a display module. In doing so, a grayscale within a range from the second predetermined value to the maximum value is used according to the need. As a result, overshoot driving is feasible in the first sub frame, and hence it is possible to restrain the decrease in the moving image quality due to an insufficient response of an image display panel, in all types of combinations of image signals in the current frame and the previous frame.

摘要： A modulation unit is disclosed which compares video data on a current frame to a representative value of the preceding frame from a frame memory and corrects the video data so as to emphasize the gradation transition from the gradation indicated by the representative value of the preceding frame to the gradation indicated by the video data when outputting the video data. Furthermore, a judgment unit compares the both data and judges which of the value calculated from the frame representative value by the representative value generation unit and the video data is to be stored in the frame memory until the next frame. Thus, it is possible to realize a liquid crystal display device having a comparatively small circuit size (or calculation amount) for suppressing the phenomenon of image quality lowering upon display of a moving picture caused by the synergistic effect between the emphasis modulation and the pixel response shortage even when the pixel response speed is increased.

摘要： In cases where the amount of gradation transition is greater than a threshold value, a modulation processing section corrects image data D of a current frame by making an interpolation calculation with reference to a look-up table, and output the image data D thus corrected. In cases where the amount of gradation transition is not more than the threshold value, the modulation processing section directly outputs the image data D of the current frame. Furthermore, in one embodiment of the present invention, the look-up table contains, as output image data D2 corresponding to a case where the image data D of the current frame is identical to image data D0 of a previous frame, a value which is neither of the image data D of the current frame and the image data D0 of the previous frame and by which output image data D2 corresponding to the inputted image data D and D0 of the previous and current frames is calculated according to the interpolation calculation in cases where the amount of gradation transition is greater than the threshold value. With this, an image display apparatus is realized which can be balanced between a reduction in circuit size and an improvement in display quality at a higher level.
