Abstract
A gamma voltage generator including an operation amplifier, a first reference impedance unit, a second reference impedance unit, a first variable impedance unit, a second variable impedance unit, and a select unit is provided. The operation amplifier generates an amplified output voltage. The first reference impedance unit receives a first gamma voltage, and the second reference impedance unit receives a second gamma voltage. The first variable impedance unit provides a first variable impedance, and the second variable impedance unit receives the first gamma voltage and provides a second variable impedance. The select unit selects the amplified output voltage or the first gamma voltage according to a control signal to generate an interpolated gamma output voltage.
