ABSTRACT:
A digital-to-analog converter includes a full-type decoder, a fractional decoder and an averaging amplifier. The full-type decoder is configured to select, based on N-bit digital data, one of a set of first gamma reference voltages corresponding to a first interval of gamma reference voltages. The fractional decoder is configured to receive a set of second gamma reference voltages corresponding to a second interval of gamma reference voltages, and is configured to generate, based on the N-bit digital data, a plurality of output voltages including one of a pair of adjacent gamma reference voltages in the set of second gamma reference voltages. The averaging amplifier is configured to output an average of the plurality of output voltages of the fractional decoder. A source driver for a display panel includes a digital-to-analog converter as described.
