Abstract:
The present invention discloses an integrated source driver for a liquid crystal display device. The integrated source driver includes a reference voltage generating circuit, for providing a plurality of adjustable voltage ranges within a supply voltage and a ground level, and a reference voltage selecting circuit, including a plurality of digital to analog converters, for selecting and generating a plurality of internal reference voltages from the plurality of adjustable voltage ranges, respectively. The plurality of adjustable voltage ranges decrease progressively.
