ABSTRACT:
A COG type LCD device and method are disclosed, which improve picture quality by minimizing driving voltage drop. The device according to an embodiment comprises an image area including a thin film transistor and a pixel electrode in a pixel region defined by gate and data lines crossing each other. A plurality of drive IC chips are formed using a COG (Chip On Glass) method in the periphery of the image display area. A LOG (Line On Glass) line is provided for cascading the plurality of drive IC chips to divide various signals inputted from an external driving circuit and to provide the divided signals to the respective drive IC chips. The LOG line includes analog and digital power lines. First and second switches are provided between the analog and digital power lines so as to temporarily short the analog and digital power lines.
