Abstract
Provided are a TFT-LCD source driver employing a frame cancellation and half decoding method, and a source line driving method. The TFT-LCD source driver outputs source line driving voltages for every two channels among a plurality of channels. Positive first and second gray scale voltages generated by a positive half decoder and negative first and second gray scale voltages generated by a negative half decoder are selectively transmitted to first and second output buffers through a chopping multiplexer in response to a chopping control signal. Output signals of the first and second output buffers are output to first and second channels through a polarity multiplexer in response to a polarity control signal.
