APPARATUS FOR IMPROVING EMI OF LIQUID CRYSTAL DISPLAY DEVICE

摘要

An electro magnetic interference attenuator of a liquid crystal display is provided to reduce the EMI(Electro Magnetic Interference) without an additional expense by lowering the frequency of the read clock signal. An electro magnetic interference attenuator of a liquid crystal display comprises a timing controller(31), a gate driving unit(32), a data driving unit(33), and a liquid crystal panel(34). The timing controller samples the RGB data inputted from system, re-arranges and outputs. The timing controller lowers the frequency of the read clock signal of the RGB data. The gate driving unit supplies the gate pulse to each gate line(GL1~GLn) of the liquid crystal panel. The data driving unit supplies the pixel signal to each data line(DL1~DLm) of the liquid crystal panel.
