FLEXIBLE PRINTED CIRCUIT FOR CONNECTING TOUCH SCREEN AND LIQUID CRYSTAL DISPLAY USING THE SAME

摘要

PURPOSE: A flexible printed circuit board (FPCB) for connecting a touch screen and a liquid crystal display (LCD) device using the same are provided to remove noise including a sensing signal applied to a touch integrated circuit (IC) by forming a touch line connected to a touch electrode formed on the touch screen and a feedback compensation signal electrode for remove noise generated in a panel. CONSTITUTION: Touch lines (633) are connected to touch electrode lines, are attached on a first film (634). A second film (632) is overlapped with the first film and wraps the touch lines. A feedback compensation signal electrode (635) is attached on the lower surface of the first film and receives a feedback compensation signal for removing noise. Touch line pads connected to touch line pins of a touch board connector are formed at the end of the touch lines. A feedback compensation signal electrode pad connected to the feedback compensation signal electrode pin of the touch board connector is formed at the end of the feedback compensation signal electrode.
