LIQUID CRYSTAL DISPLAY AND DRIVING METHOD THEREOF

摘要

An LCD device and a driving method thereof are provided to drive a timing controller by using a logic voltage for minimizing EMI(ElectroMagnetic Interference). An LCD(Liquid Crystal Display) device includes a timing controller and a regulator(130). The timing controller receives synchronous and data signals from a main system. The regulator supplies logic voltages according to EMI corresponding to frequency control signals from the main system to the timing controller. The regulator includes a memory(132) and a voltage stabilizer(134). The memory stores selection signals corresponding to the frequency control signals. The voltage stabilizer generates the logic voltages corresponding to the selection signals supplied from the memory.
