  • Patent number: 8199307
    Abstract: A liquid crystal display includes: a liquid crystal panel assembly including pixels, gate lines, data lines and a first gate driver; and a driving chip disposed on the liquid crystal panel assembly. A shape of the liquid crystal panel assembly is rectangular and the liquid crystal panel assembly includes a long edge and short edge. The gate lines extend in a same direction as the short edge, and the data lines extend in a same direction as the long edge. The pixels are disposed in pixel rows and are connected to the gate lines and the data lines. The first gate driver is disposed on a peripheral area of the long edge, and the driving chip is connected to the data lines.

  • Publication number: 20080088337
    Abstract: An apparatus for inspecting a display device includes an inspection substrate and a power supply part. The inspection substrate is electrically connected to a flexible circuit film that is connected to a display panel of the display device. The inspection substrate outputs inspection signals inspecting a connection between the display panel and the flexible circuit film. The power supply part is electrically connected to the inspection substrate. The power supply part provides driving power to the display panel. Thus, the inspection substrate is electrically connected to the flexible circuit film. Manufacturing costs for the apparatus may be reduced and the connection between the display panel and the flexible circuit film may be inspected.

  • Publication number: 20070195052
    Abstract: A source driving apparatus includes a latch, an additional-data generator, an output controller and a buffer. The latch latches a normal-data signal received and outputs the latched normal-data signal. The additional-data generator generates an additional-data signal having a low value on the gray-scale and outputs the additional-data signal. The output controller controls the additional-data generator to output the generated additional-data signal during an invalid data interval of a predetermined frame. The buffer buffers the normal-data signal and the additional-data signal and outputs the normal-data signal and the additional-data signal. Therefore, instantaneous afterimage phenomenon may be eliminated by changing the structure of the source driver.
