摘要： With regard to each of primary colors for image display on the image display panel, (i) three video signals are extracted from each of video signal rows of J types in which the video signals supplied to pixels are aligned in line with time series, in such a manner as to cause the order of primary colors reproduced by the three video signals to be in line with the order of the J primary colors allocated to the respective pixels, and (ii) video signal rows of three types are generated by serially allocating each of the three video signals to any one of the video signal rows of three types.

摘要： A liquid crystal display device includes a liquid crystal display panel and a driving circuit that supplies display signals to a plurality of subpixels of the liquid crystal display panel. The plurality of subpixels are a red subpixel, a green subpixel, a blue subpixel, and a yellow subpixel. When achromatic colors of at least some gray levels among all gray levels are to be displayed by the pixel, display signals which are supplied to a first subpixel group composed of certain two subpixels are display signals of the same grayscale level, whereas display signals which are supplied to a second subpixel group composed of the other two subpixels are display signals of a different grayscale level from the grayscale level of the display signals supplied to the first subpixel group. The first subpixel group includes the yellow subpixel, and the second subpixel group includes the blue subpixel.

As long as the sum of respective luminances of all of the subpixels but the blue subpixel (B) falls within the range of 0% to 50% while the color displayed by the pixel is changing from the color blue in which the blue subpixel (B) is at the highest grayscale level and the other subpixels are at the lowest grayscale level into the color white in which all of those subpixels are at the highest grayscale level substantially without changing its hue, the yellow subpixel (Ye) starts to increase its grayscale level at a different timing, and/or has its grayscale level increased at a different ratio with respect to an increase in the pixel's luminance, from the red and green subpixels (R, G) do.

摘要： Viewing angle characteristics on the entire display surface are improved while suppressing harmful effects such as flicker and banding caused by viewing angle improvement control. A liquid crystal display apparatus (1) includes: a liquid crystal panel (11) which includes a plurality of pixels arranged in a matrix; a drive control unit (24) which performs viewing angle improvement processing by converting a gradation of a video signal input to the pixel; and a processing object determination unit (22) which determines whether or not an image displayed on each of the pixels of the liquid crystal panel (11) is an image having an intermediate color. The drive control unit (24) is configured to perform the viewing angle improvement processing on the pixel determined by the processing object determination unit (22) such that the pixel displays the image having the intermediate color.

摘要： An image display period of a first sub frame of an N-th frame is arranged to partly overlap the image display period of the second sub frame of the N-th frame and the image display period of a second sub frame of the (N−1)-th frame. Grayscale display voltages with which pixels that are horizontally or vertically neighbored are charged are arranged to have inverse polarities, and the polarity of the grayscale display voltage charging each pixel is reversed in each frame. Furthermore, neighboring data signal lines are short-circuited each time the polarity of the grayscale display voltage output to each data signal line is reversed.
