Abstract
A gamma voltage generator within a display device includes a plurality of gamma generation circuits that respectively generate a plurality of gamma voltages. At least one gamma generation circuit includes an input circuit configured to receive a first reference voltage and a second reference voltage, a reference voltage select circuit configured to select a reference voltage among the first reference voltage and the second reference voltage by comparing a gamma voltage generated by the at least one gamma generation circuit with the first reference voltage and the second reference voltage, a digital-to-analog conversion circuit configured to generate an analog voltage corresponding to a gamma code based on the reference voltage selected by the reference voltage select circuit, and an output circuit configured to output the gamma voltage based on the analog voltage.
