摘要： Data signal lines are provided to pixel arrays such that adjacent first and second pixel arrays (α, β) and including plural pixels are provided with two data signal lines each. Each pixel includes a pixel electrode (17a). The two scanning signal lines (16a, 16b) are selected concurrently. Respective pixel electrodes (17a, 17b) for pixels (101, 102) are connected with a data signal line (15x) and a data signal line (15y), respectively. Input gray scales of data signals inputted to the display device externally is corrected such that if input gray scales of data signals to be supplied respectively to the pixel electrodes (17a, 17b) are different from each other, the input gray scales are corrected to cause a gray scale difference between post-correction gray scales to be greater than that between the input gray scales. Display is carried out with the post-correction gray scales.

摘要： Image data obtained by adding a dummy image to a periphery of inputted image data is divided into blocks which correspond to positions of LEDs. A light-emitting luminance of an LED in an image display area is determined in accordance with a maximum value among gradation values of pixels included in a block corresponding to the LED. A light-emitting luminance of an LED in an image non-display area is determined in accordance with an average luminance level of some of small blocks which are adjacent to the block corresponding to the LED in the image non-display area, the small blocks being obtained by further dividing a block of the image display area adjacent to the block corresponding to the LED.

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.

摘要： Pixels belong to any of a plurality of pixel groups. The pixel groups each include first pixels and second pixels. A three-dimensional image display apparatus polarizes light to be emitted from the first pixels into light having a first polarization characteristic and polarizes light to be emitted from the second pixels into light having a second polarization characteristic. The three-dimensional image display apparatus, sets luminance of at least one of luminance of a left-eye image or luminance of a right-eye image such that the luminance of a predefined first image of the left-eye image or the right-eye image is higher than the luminance of a second image of the images. The three-dimensional image display apparatus causes the first pixels to render the first image at the set luminance on a screen and causes the second pixels to render the second image at the set luminance on the screen.
