Abstract:
1. A COG panel system, comprising: an FPC configured to supply a bypass power supply voltage and a correction power supply voltage having a constant voltage level; a plurality of SDIs comprising a foregoing SDI and a following SDI which are commonly supplied with the bypass power supply voltage from the FPC and are configured to generate respective portions of a plurality of consecutive LCD driving signals required for an arbitrary one line of an LCD; and at least one block dim correction resistance to the foregoing SDI, wherein the correction power supply voltage is applied from the FPC through the block dim correction resistance to only the foregoing SDI, wherein a total specific resistance of a line for the correction power supply voltage as seen from an output terminal of the foregoing SDI through which a last LCD driving signal among the foregoing LCD driving signals of the foregoing SDI is output is equal to a total specific resistance of a line for the bypass power supply voltage as seen from an output terminal of the following SDI through which a first LCD driving signal among the following LCD driving signals of the following SDI is output, and wherein the correction power supply voltage is supplied through the block dim correction resistance and then supplied to the foregoing SDI first at the output terminal through which the last LCD driving signal among the foregoing LCD driving signals of the foregoing SDI is output.
