SOURCE DRIVING INTEGRATED CIRCUIT OF LCD MODULE AND SOURCE DRIVING SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a source driving integrated circuit of an LCD module that can improve an image quality deterioration problem and decrease the number of components of an LCD module, and to provide a source driving system using the same.;SOLUTION: A voltage output section that the source driving integrated circuit includes is equipped with a gamma buffer section that buffers a self-gamma-correction voltage inputted from one side of a gamma correction voltage generation section and outputs the buffering self-gamma-correction voltage to outside the source driving integrated circuit chip, an output D/A converter that inputs a buffering other-gamma-correction voltage as an other-gamma correction voltage outputted from the other side of the gamma correction voltage generation section and the buffering self-gamma correction voltage from outside the source driving integrated circuit chip to convert a digital data signal from a data register into an analog signal and outputs it, and an output driving circuit which converts the analog data signal from the output D/A converter into a driving voltage for source line driving and outputs it.;COPYRIGHT: (C)2006,JPO&NCIPI
