  • Liquid crystal display device
    Patent number: 7719640
    Abstract: In a multi-gap semi-transmissive liquid crystal display device, the width of a black matrix (6) is made larger above the region between adjacent ITO transparent electrodes (3) and is made smaller above the region between adjacent Al reflective electrodes (4). This enables a transmissive portion to offer a display with high contrast that does not suffer from afterimage or the like by shielding light from the domain lying between the adjacent pixels, and the reflective portion to offer a brighter display by increasing the aperture ratio thereof by making the black matrix width as small as possible or forming no black matrix.

  • Thin film transistor, fabrication method thereof, liquid crystal display panel device having the same, and fabrication method thereof
    Patent number: 7710525
    Abstract: A TFT that provides an efficient layout, a fabrication method thereof, an LCD device having the TFT, and a fabrication method thereof are provided. The TFT has a gate electrode and source/drain electrodes with an active layer interposed. The source electrodes and the drain electrodes are alternated in a vertical direction and a horizontal direction. Thus, the same source electrodes and the same drain electrodes are arranged in a diagonal direction. Source lines are connected with the source electrodes arranged in a diagonal direction and drain lines are connected with the drain electrodes arranged in a diagonal direction. Since a channel width is formed between the source electrode and adjacent drain electrodes, the channel width can be maximized within a limited area. Also, the source lines and the drain lines are arranged in a diagonal direction, so that an area use rate is maximized.

  • Monitoring individual fibers of an optical cable for intrusion
    Patent number: 7706641
    Abstract: Some or all of the optical fibers of a single-mode or multi-mode cable are monitored for intrusion by transmitting through the fibers a signal which can be analyzed for changes in its characteristics which are indicative of movement as a prelude to an intrusion event. To avoid independent monitors of all of the fibers, in some cases the same light signal is looped through a plurality of the fibers in series by passive jumpers. Switches can be used to disconnect out those fibers which are compromised. As an alternative a plurality of separate monitoring signals can be provided each associated with its own sensor where unique combinations of the signals are transmitted through separate fibers allowing a higher number of fibers to be monitored than the number of signals.
