Patent ID: 7310094

Claim:
A method of driving a liquid crystal display device, comprising: receiving a plurality of timing synchronization signals from an interface; generating a pre-synchronizing signal, the pre-synchronizing signal having a frequency identical to a first one of the plurality of the received timing synchronization signals; generating one of a first determining signal when the first one of the plurality of received timing synchronization signals is received from the interface during a first predetermined period of the pre-synchronization signal and a second determining signal when the first one of the plurality of received timing synchronization signals is not received from the interface during a second predetermined period of the pre-synchronization signal; and generating control signals for driving a liquid crystal display device, wherein the control signals are based on a generation of one of the first and second determining signals, wherein control signals based on the generation of the first determining signal include the first one of the plurality of received timing synchronization signals, and wherein control signals based on the generation of the second determining signal include the pre-synchronization signal.
