Abstract: Light from an image displayed on a display screen 10 is transmitted to an observer's eye 11 by way of a dynamic optical element 12 (such as a spatial light modulator or an electrically switchable holographic composite) which acts as a lens. The characteristics of the dynamic optical element 12 can be altered so that it acts sequentially to direct light of different colors to the observer's eye. In one optional embodiment emitters 17 on the display screen 10 emit infra-red radiation which is projected by the dynamic lens 12 as a broad wash onto the eye 11. Infra-red radiation reflected back from the eye 11 is focussed by the dynamic lens 12 onto detectors 18 also provided on the display screen 10. The detectors 18 are thus able to sense the direction of eye gaze, and the dynamic lens 12 is controlled in dependence on this to create an area of high resolution in an area of interest centered on the direction of gaze, which is moved to follow the eye gaze as its direction alters.

Abstract: On a liquid crystal device substrate 1, a capacitor 85 is provided between reset signal lines 81 and 82 for applying reset potentials to the respective data lines prior to the supply of the image signals to the data lines, and a potentiostatic line 84.

A liquid crystal device and a projection display device employing the liquid crystal device prevent signals from circulating from data lines via a reset signal line, thus permitting higher quality of display to be achieved.

A reset period is provided in a first sub-frame of the sub-frame block so as to initialize all pixels prior to the address period.

Abstract: A control circuitry for conveying video data in a flat panel display transmits video data using reduced swing differential signals that are time-multiplexed on a data bus. Data transmission schemes are provided to reduce data transitions on the data bus. A repeat last pixel scheme is used whenever the pixel data repeat horizontally on a display. A repeat last line pixel scheme is used whenever the pixel data repeat vertically on a display. A repeat last different pixel scheme is used whenever video data comprises mainly of monochrome information. In the alternate, a dynamic color pallet is used to store a few most frequently used pixel colors. When the current pixel color matches one of the colors stored, a pixel color address is transmitted instead of the pixel data itself. The use of reduced swing differential signaling on a time-multiplexed data bus together with one or more of the data transmission schemes achieves significant reduction in power consumption and electromagnetic interference generation.

Abstract: A keyboard input apparatus, where a plurality of main keys are pressed for character inputting operation. Five keys are set individually as character keys for inputting characters “A”, “I”, “U”, “E”, and “O” of the Alphabet expressing vowels. Further provided are key input detectors to detect the number of key pressing operations of each of the main keys, and a key input processor for outputting the character keys corresponding to the number of key pressing operations. Setting of in the Japanese and English language frequently used vowels on independent keys enables inputting of vowels by only a single key pressing operation and when compared with a conventional art where a plurality of key pressing operations are required, the number of key pressing operations can be reduced at the time of inputting vowels, whereby manipulation of the apparatus and the inputting speed can be improved.
