Abstract
A thin film transistor (TFT) liquid crystal display panel driving device and a method thereof are provided. The TFT liquid crystal display panel driving device is characterized by including a modulation signal generator for providing at least one modulation signal to at least one output buffer of a source driver of the TFT liquid crystal display panel. The output buffer(s) has chopper function. Each output buffer changes the offset voltages of the pixels of a same frame under the control of different modulation signals, thus eliminating the effect of the offset voltages of the output buffer(s) on the display quality.
