  • Patent number: 5941933
    Abstract: Provided is an information transmitting apparatus for transmitting information to an external receiving apparatus by means of a radio wave comprising: a control information attaching device for attaching control information representing a control processing method on the receiving apparatus side of the information to the information to be transmitted; and a transmitting device for transmitting information to which the control information is attached. Further provided is an information receiving apparatus for receiving and displaying transmitted information comprising: a receiving device for receiving the transmitted information; a display device for displaying the received information; and information processing device operating, when control information representing a control processing method of the received information is attached to the received information, to execute information processing corresponding to the control information.

  • Patent number: 4963503
    Abstract: A liquid crystal display device comprises, a plurality of display electrodes which are selectively energized through on-off control of thin film transistors. In order to reduce the channel length of the thin film transistors to increase operation speed and obtain uniform characteristics each display electrode and an associated transistor source electrode is formed on one of a pair of transparent substrates of the liquid crystal display device, a semiconductor layer is formed between the display electrode and source electrode, a gate insulating film is formed on the semiconductor layer, and a gate electrode is formed on a portion of the gate insulating film between the display electrode and source electrode. Then, ions are implanted into the semiconductor layer with the gate electrode used as a mask, thus rendering portions of the semiconductor layer contiguous to the display electrode and source electrode into ohmic layers.

  • Patent number: 4881797
    Abstract: A color liquid crystal display device comprises first and second transparent substrates, and a liquid crystal sealed therebetween. A plurality of display electrodes and thin film transistors each connected to each of the display electrodes are formed on the first transparent substrate. Color filters are formed on the second transparent substrate such that they each face each of the display electrodes. A common electrode is also formed over the entire surface of the second transparent electrode. The gap between adjacent color filters is closed by a metal layer capable of blocking light. These light-blocking layers overlie the common electrode in contact therewith.

  • Patent number: 4687298
    Abstract: A liquid crystal display device is disclosed, which comprises first and second transparent substrates facing each other, a liquid crystal sealed between the transparent substrates, a plurality of display electrodes formed on the inner surface of the first transparent substrate, thin film transistors also formed on the first transparent substrate inner surface and each connected to each display electrode, and a transparent common electrode formed on the inner surface of the second transparent substrate, and in which the thin film transistors are selectively controlled to selectively drive the display electrodes for display. The resistance of semiconductor layers of the thin film transistors is reduced by external light to result in deterioration of the contrast of display. According to the invention, an opaque metal layer is formed between each thin film transistor and the first transparent substrate, and an insulating film is provided between the opaque metal layer and thin film transistor.
