Abstract
A gamma voltage generation circuit coupled to a digital-to-analog converter and provides the digital-to-analog converter with reference voltages by voltage division through resistor circuits. A variable voltage source can be modulated and charge-sharing switches can be included to save power. The reference voltage generation circuit can adopt output buffers that further improve the driving capability of the reference voltage generation circuit.
