Abstract: Provided is a projection type liquid crystal display apparatus, which can improve black-level display and thus can display a higher-contrast image as compared to the related art. An optical compensator is located on the light exit side with respect to the liquid crystal display device so as to compensate for the optical phase difference caused by liquid crystal molecules in a light-entry-side region of the liquid crystal layer. As the optical compensator is located on the light exit side with respect to the liquid crystal display device, birefringence, caused by the liquid crystal molecules present in the light-entry-side region, is compensated for without being influenced by a microlenses provided in the liquid crystal plane. Consequently, the apparatus can improve the black-level display and thus can display a higher-contrast image as compared to the related art. Further, a phase difference caused by the birefringence of the nematic liquid crystal molecule is compensated for by using a substance having properties optically opposite to the positive crystal, namely, a substance having birefringence equivalent to birefringence of a negative crystal.

Abstract: Image data of the respective colors are converted, by look-up tables in which &ggr; correction data are stored, into gradation data that are white-balanced with intervention of the V-T characteristics of liquid crystal panels. The generated gradation data are supplied to D/A converters and the liquid crystal panels via liquid crystal driving circuits. Gamma correction data within dynamic ranges that are set for each display apparatus by measuring a luminance ratio and contrast ratios of the respective colors are written to the look-up tables in advance. As a result, all they correction data stored in the look-up tables can be used effectively. The invention is directed to such a method for generating data of look-up tables and an image display apparatus that performs gradation correction by using thus-formed look-up tables.

Abstract: An image display apparatus and a liquid-crystal display device using such an optical filter for diffusing pixels while suppressing the occurrence of moire. A diffuser (optical filter) 13 comprising a combination of a diffraction grating 26 and a birefringence plate 27 is disposed on an LCD 11 in an opposing relation to the viewer side. The diffraction grating 26 diffuses each pixel of the LCD 11 into three points in the vertical direction by a shift amount of POy/3 (POy: same color pixel pitch in the vertical direction). Further, the birefringence plate 27 diffuses each diffused pixel into two points in the horizontal direction by a shift amount of Pox/2 (Pox: same color pixel pitch in the horizontal direction). Thus, the diffuser 13 diffuses each pixel of the LCD 11 into six pixels to thereby optically erase a matrix-like pixel pattern. The diffraction grating 26 diffuses pixels by a large shift amount, whereby a total thickness of birefringence plate can be suppressed from increasing as compared with an optical filter for diffusing pixels by use of only a birefringence plate. Since the diffraction grating 26 diffuses pixels by a large shift amount, a grating pitch can be reduced, and the occurrence of moire can be suppressed.

Abstract: A picture display apparatus is provided with a display device having pixels disposed in a mosaic pattern. A plurality of optical filter surfaces are respectively placed between the display device and a viewer so that the both surfaces can be overlapped with each other. Each pixel in the display device is diffracted or refracted by both surfaces to become a plurality of pixels.

Abstract: An imaging system comprises left and right display panels arranged so as to be viewed separately by left and right eyes of a viewer. A three dimensional video signal is supplied to a drive circuit for the display panels such that image data from the three dimensional video signal is supplied alternately to the left and right display panels. The display panels are of a memory effect LCD type such that, when no image data is received by the display panel, the image data of the previously received field is maintained on display for providing `flickerless` imaging.

Abstract: In a video signal display apparatus having a liquid crystal display unit with liquid crystal cells arranged in a matrix for displaying a display signal developed from an input video signal, the supplying of a scanning signal to the liquid crystal display unit is inhibited during a period in which an unnecessary portion of the video signal is provided, for example, as when the input video signal is derived from a VTR in a variable speed reproducing mode, and, during such inhibition of the supplying of the scanning signal to the liquid crystal display unit, the latter is made to continuously display the display signal previously supplied to the liquid crystal cells.
