Abstract:
A TFT-LCD driver comprising:a TFT-LCD panel having a plurality of gate bus lines, a plurality of source bus lines, a plurality of TFT's, and a plurality of liquid crystal cells corresponding to the plurality of TFT's; a gate driver integrated circuit for supplying driving voltages to the gate bus lines to turn the TFT's on and off; a source driver integrated circuit for initially supplying analog voltages having a polarity and sequentially supplying analog voltages having an opposite polarity to the source bus lines so as to input the analog voltages to the plurality of liquid crystal cells through the turned-on TFT's; a controller for providing control signals to the gate driver integrated circuit and the source driver integrated circuit; and a data register for temporarily storing external data and grouping the external data into a plurality of sub-fields, wherein the source driver integrated circuit drives the TFT-LCD panel using one of a dot inversion method and a pixel inversion method.
