An exemplary data driver chip ( 23 ) includes a multiplexer ( 31 ); a first digital/analog (D/A) converter ( 32 ); and a second digital/analog (D/A) converter ( 33 ). The multiplexer receives a multiplex data stream and decomposes the multiplex data stream to a first signal and a second signal, and respectively sends the first and second signals to the first and the second D/A converters. The first D/A converter converts the first signal to an analog gamma voltage to the second D/A converter, and the second D/A converter converts the second signal to analog video signal according to the analog gamma voltage.
