GAMMA VOLTAGE GENERATING APPARATUS AND METHOD FOR GENERATING GAMMA VOLTAGE

摘要

A gamma voltage generating apparatus and a method for generating a gamma voltage are provided. The gamma voltage generating apparatus includes a plurality of digital-to-analog converter units, a resister string and a plurality of selecting units. The digital-to-analog converter units generate a plurality of curve reference voltages. The resister string includes a plurality of resistors connected in series with each other to provide a plurality of endpoints. A part of the endpoints are set to be a plurality of curve turning intervals. Each of the selecting units respectively corresponds to each of the digital-to-analog converter units and each of the curve turning intervals. Each of the selecting units selectively provides each of the curve reference voltages to one of the endpoints of a corresponding of the curve turning intervals.
