TIMING CONTROLLER, ITS DRIVING METHOD, LIQUID CRYSTAL DISPLAY DEVICE USING THE SAME

摘要

PURPOSE: A timing controller, a driving method thereof, and a liquid crystal display device using the same are provided to prevent malfunction of a phase fixed loop of a data drive IC by preventing outputting of an abnormal image. CONSTITUTION: A LVDS(Low Voltage Differential Signaling) receiving part(410) receives video data and input SDCLK(Spread spectrum Dot Clock). A delaying part(450) receives the input SDCLK through the LVDS receiver. The delaying part outputs the output SDCLK in which the instant abnormal clock is filtered. A processing part(470) generates a gate control signal and a data control signal. The processing part rearranges and outputs the video data received from the LVDS receiving part. An EPI transmitting part(440) outputs the rearranged video data and the data control signal to each data drive IC.
