  • Patent number: 7911575
    Abstract: It is disclosed a liquid crystal display having an electrode pad for compensating for differences in resistance of electrode links. The liquid crystal display including a pixel area and a driving circuit, comprises at least two electrode links each extended from the pixel area; and at least two pads in contact with the driving circuit and the electrode links, each pad being in contact with each electrode link and having a non-resistivity that depends on a length of the each electrode link. Accordingly, resistance differences that depend on the length of the electrode links are compensated for using electrode pads, thereby making signal conductors with substantially equal resistances.

  • Patent number: 7777852
    Abstract: In a liquid crystal display unit where a matrix pattern of pixels are defined by gate lines and crosswise data lines, transparent pixel electrodes are formed on the same layer as the data lines and corresponding transparent common electrodes are formed above the transparent pixel electrodes. On the common electrodes the liquid crystal layer is provided. In the aperture of each pixel, the common electrode has a pattern of parallel stripe portions and a peripheral portion outside of the aperture for shielding the field of the corresponding data line. Each pixel electrode cooperates with that parallel stripe portions of the corresponding common electrode to produce inner fringe fields along such parallel stripe portions and has portions that overlap the peripheral portions of the common electrode to produce peripheral fringe fields so that liquid-crystal cells can be uniformly in-plane switched by the inner fringe fields as well as by the peripheral fringe fields.

  • Patent number: 7764351
    Abstract: A method for improving a misalignment of a printed circuit board and a liquid crystal display device with the printed circuit board are disclosed. A printed circuit board having a substrate and PCB lands formed at a portion of the substrate in the horizontal direction is provided and a tape carrier package having TCP leads corresponding to the PCB lands is also provided. The intervals among the PCB lands are amended by the thermal expansion amount of the substrate. After the printed circuit board and the tape carrier package are aligned, the printed circuit board and the tape carrier package are connected to each other by the thermo-compression bonding process. The misalignment due to the thermo-compression bonding process can be improved, decreasing the processing failures and increasing the productivity.
