  • Liquid crystal display and method for repairing the same
    Patent number: 8154704
    Abstract: A method for repairing a liquid crystal display. The method includes preparing a liquid crystal panel including a signal pad part and a repair pad part connected to signal lines; testing a driving circuit connected to the signal pad part on the liquid crystal panel; opening signal links connecting the signal lines and the signal pad part, connected to the driving circuit, if the driving circuit is detected in a defect as a result of the test; and mounting a repair driving circuit to be connected to the repair signal pad part on the liquid crystal panel.
    Type: Grant
    Filed: December 11, 2008
    Date of Patent: April 10, 2012
    Assignee: LG Display Co., Ltd.
    Inventors: Myoung Kee Baek, Kwang Ho Jang
  • Liquid crystal display device and method of manufacturing the same
    Patent number: 8027009
    Abstract: A liquid crystal display device and a method of manufacturing the same are disclosed. The liquid crystal display device includes a liquid crystal panel including gate pads connected to gate lines and data pads connected to data lines; at least one driving circuit mounted on a circuit substrate including poly-silicon thin-film transistors, formed by a low temperature poly-silicon (LTPS) process, and including circuit pads to be connected to the gate pads or data pads; and a conductive film to electrically connect the driving circuit and the gate pads or data pads.
