Abstract
A gamma voltage generation circuit is provided. The gamma voltage generation circuit includes a resistor string, a first switch, and a second switch. The resistor string includes a plurality of resistors connected in series. An output terminal of the first switch is coupled to a first end of the resistor string. An output terminal of the second switch is coupled to a second end of the resistor string. The first switch selects and outputs one of a first high reference voltage and a second high reference voltage to the first end of the resistor string according to a control signal. The second switch selects and outputs one of a first low reference voltage and a second low reference voltage to the second end of the resistor string according to the control signal.
