    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.

    摘要： An image display system stereoscopically reproduces a visual scene and includes an image display unit with a pair of LCD panels each starting its operation in response to a start pulse received every vertical field of an input video signal; a source of input video signals representing right and left stereoscopic video images every field; a circuit for generating right and left start pulses, which are mutually in an opposite-phase relationship, in synchronism with the arrival of the right and left video images; and a driver for driving the pair of LCD panels by the right and left start pulses. The image display unit is shaped into a virtual viewer incorporated in a ski-goggle type frame which is adapted to be worn on a user's head. The video images displayed on the two LCD panels are refreshed alternately to obtain a flickerless image without the necessity of employing any particular circuit or terminal.

    摘要： In an apparatus for recording and/or reproducing a television signal with multiplex audio signals, a pilot signal is recorded on one or both of the audio tracks of a video tape in a manner to identify the mode of the multiplex audio signals and each pilot signal is detected to establish such mode when reproducing. For example, the frequency of the pilot signal may be changed for identifying different modes of the multiplex audio signals, such as, the bilingual mode and the stereo-phonic mode, with the pilot signal of selected frequency being recorded on one of the audio tracks, or the pilot signal having a certain frequency is recorded on one of the audio tracks in the case of the bilingual mode, and on the other audio track of the tape in the case of the stereo-phonic mode. In still another embodiment, the pilot signal is recorded in both audio tracks of the tape and the phase relation of the recorded pilot signals is varied to identify the mode of the multiplex audio signals.

The corrected image signal is supplied to the liquid crystal panel with the positive polarity in the positive field and the corrected image signal is supplied to the liquid crystal panel with the negative polarity in the negative field.

    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.
