PURPOSE: A filter circuit is provided to effectively eliminate noise and EMI of all bands for TFT-LCM. CONSTITUTION: A filter circuit comprises an input resistor(11), a bid(12) and an output resistor(13). The input resistor(11) reduces a rising noise in an external signal applied from a system, so that an amplitude is reduced. The bid(12) is parallel connected to the input resistor(11). The bid(12) generates a magnetic repulsive force to reduce a noise having a special resistance to a special frequency within a signal band. The output resistor(13) is parallel connected to the bid(12). The output resistor(13) reduces a falling noise so that amplitude of the input signal has a gentle slope. |
