摘要： 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. For each optical filter surface, an element for diffusion such as a diffraction grating and an element for refraction such as a prism can be utilized for the diffraction and refraction.

摘要： 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.

摘要： 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.

摘要： A picture display apparatus exploiting a liquid crystal display is disclosed. This picture display apparatus (10) includes an interpolator (11), an over-drive unit (12), an angle of visibility improvement unit (13), and a source driver (15) for driving a liquid crystal display panel (16). The interpolator converts the picture rate upwardly. The angle of visibility improvement unit (13) converts an input picture signal into a picture signal representing a grayscale level of the input picture signal by synthesis of liquid crystal transmittances of a plural number of temporally consecutive fields. Specifically, the angle of visibility improvement unit converts the input picture signal to a picture signal made up of a first field set to a signal value related with a high grayscale level and a second field set to a signal value related with a low grayscale level. In case time changes of the grayscale level have occurred in the input picture signal at the same spatial position, the over-drive unit (12) corrects the driving level for a signal value of one or both of the first and second fields depending on response of the liquid crystal.

摘要： Linear chromaticity conversion is used to perform color reproduction of a liquid crystal display (LCD) compatible with a cathode ray tube (CRT). An inputted signal is subjected to processing similar to processing used in the CRT display. A light source chromaticity conversion processing portion carries out a γ correction to the signal in a γ operation portion by using γ1=γcrt of the same nonlinear characteristics as the CRT, and performs an operation of a chromaticity conversion matrix in a matrix operation portion. An LCD inverse γ correction portion uses γ2 establishing γ_lcd=γlcd/γ2=1 to perform an inverse γ correction to the inputted signal. An LCD γ characteristic operation portion performs a γ correction using γ characteristics of the LCD to the signal inputted from the LCD inverse γ correction portion, outputs a picture signal, and causes an image to be displayed on the LCD.

摘要： 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.

摘要： A display device has a line scan driving circuit disposed in a horizontal direction of a display region and a pixel driving circuit (dot scan driving circuit) disposed in a vertical direction of the display for performing image display with pixel groups each forming one line in the vertical direction being scanned in the horizontal direction. Vertical-horizontal converting circuitry is provided for converting an image data stream supplied with n pixels in a horizontal direction and m horizontal lines in a vertical scanning direction into an image data stream with m pixels in a vertical direction and n vertical lines in a horizontal scanning direction, and the vertical-horizontal converted data is supplied to the display device by a display controlling circuit. That is, image data is supplied to the displaying device as a vertical-horizontal converted data stream and display operation is executed by vertical pixel rows being scanned in the horizontal direction, as a result of which the relatively small line scan driving circuit is disposed above or below the display region instead of the relatively large dot scan driving circuit and thus the area required for circuit mounting above/below the display region is reduced and the size of the display device in the vertical direction can be effectively reduced.
