摘要： Out of two display pixels connected to the same gate line G2, a display pixel (A) is connected to a source line S2, and a display pixel (B) is connected to a source line S3, which is adjacent to the source line S2 and forms a parasitic capacitance with a pixel electrode of the display pixel (A). A write signal for a display pixel (A) is obtained by correcting an input signal for the display pixel (A) in accordance with an input signal for a display pixel (B) or a write signal for the display pixel (B). With this arrangement, it is possible to reduce crosstalk between the two display pixels in a display device, such as a liquid crystal display device, that drives display pixels through a plurality of source lines and a plurality of gate lines.

摘要： A liquid crystal display of the present invention contains a first panel and a second panel being stacked. Adjacent pairs of polarizers (A to C) disposed on the panels form crossed Nicols. When the first panel produces a display according to a first display signal, the second panel produces a display according to a second display signal obtained from the first display signal. Each of the two joined panels is provided with a light diffusion layer having a light diffusing property. The provision of the light diffusion layers enables reducing moire pattern occurrences which would otherwise markedly increase when two liquid crystal panels are stacked. As a result, the liquid crystal display has high display quality.

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： An evaluation apparatus of a liquid crystal display device in accordance with the present invention is provided with a signal section for supplying a signal to a liquid crystal panel to be evaluated; a display detection section for sensing a display state on the liquid crystal panel; an analysis section for analyzing a detection result of the display detection section. The signal section supplies to the liquid crystal panel a signal corresponding to an original tone and then, in accordance with tone transition from the original tone to an attainment tone, either (i) an overshoot test signal or (ii) both an overshoot test signal and an undershoot test signal in test driving, while sweeping either a level of the signal (i) or levels of both the signals (ii). The analysis section analyzes detection results of the display detection section obtained in the test driving and stores in association with the original tone and the attainment tone, a level of the test signal that corresponds to an optimum one of the detection results. With this, it is possible to easily and highly accurately obtain an optimum level of the overshoot signal or the undershoot signal for the liquid crystal panel to be evaluated.

摘要： A driving system of the present invention for use in a displaying device is provided with a pseudo bit-depth extension section. In the pseudo bit-depth extension section, a noise pattern is added to upper-n-bit data of an input signal D0 in m-bit, where (i) m is an integer of 9 or greater, and (ii) n is an integer of 8 or greater, but less than m. Then, upper-n-bit of data D1 thus obtained from the D0 is outputted, as output data D2, from the pseudo bit-depth extension section. The driving system is further provided with an overshoot-driving section for carrying out an overshoot-driving with respect to each of pixels. A noise amount of the noise pattern is 1 or less in 8-bit data, and a calculation in the overshoot-driving section is carried out with n-bit data. With this driving system which adopts a combination of (a) a overshoot-driving method for enforcing liquid crystal to respond at a high speed, and (b) a bit-depth extension technology in which a number of grayscales is increased by adding noise, it is possible to provide, at a low cost, a high-definition displaying device such as a liquid crystal display, having a high-response-characteristics and a high quality of grayscale reproduction.
