Patent ID: 7834831

Claim:
A LCD (Liquid Crystal Display) device, comprising: an image display 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 formed on a periphery of the image display area; a LOG (Line On Glass) line for cascading the plurality of drive IC chips to divide a plurality of signals inputted from an external driving circuit and configured to provide the divided signals to the respective drive IC chips, wherein the LOG line including an analog power line and a digital power line; and first and second switches provided between the analog and digital power lines and configured to temporarily short the analog and digital power lines, wherein a voltage applied to the analog power line is substantially identical to a voltage applied to the digital power line, and wherein the first and second switches are configured to be temporarily closed between points of receiving a SOE (Source Output Enable) signal and a SSP (Sampling Start Pulse) signal.
