Patent ID: 6999056

Claim:
A liquid crystal monitor drive apparatus for driving a liquid crystal panel, comprising: an integrated circuit chip, the integrated circuit chip receiving an analog graphic signal, a clock signal corresponding to the analog graphic signal, and horizontal and vertical synchronous signals, the integrated circuit chip including an analog-digital converter arranged to convert the analog graphic signal into digital graphic data; a scaler for scaling the definition and timing of the digital graphic data by adjusting the timing of the graphic data based on the clock signal and adjusting the horizontal and vertical synchronous signals to match with a timing of the liquid crystal panel; and a timing controller arranged to drive the liquid crystal panel based on the scaled digital graphic data, the adjusted clock signal, and the adjusted horizontal and vertical synchronous signals from the scaler; and a peripheral circuit coupled to an inverter for driving a back light unit, the peripheral circuit operating with a frequency significantly lower than a frequency of the clock signal corresponding to the analog graphic signal.
