Patent ID: 8896513

Claim:
A gamma adjustment circuitry, comprising: a resistor string configured to provide 2 N voltage levels on 2 N respective nodes that correspond to 2 N respective gray levels to be displayed in an N-bit unit pixel of a display panel; a set of multiplexers, wherein each multiplexer in the set of multiplexers is coupled to a respective subset of the 2 N respective nodes, wherein a plurality of adjacent nodes that correspond to a respective plurality of adjacent gray levels in two respective subsets of the 2 N respective nodes is interlaced between two respective multiplexers in the set of multiplexers; a set of amplifiers, wherein each amplifier in the set of amplifiers is coupled to a respective multiplexer in the set of multiplexers; and a source driver coupled to the set of amplifiers, wherein the source driver supplies a voltage that corresponds to one of the 2 N voltage levels to the N-bit unit pixel.
