Claim 18:
19. A semiconductor device comprising:
a display panel comprising a plurality of pixels connected to a plurality of gate lines and a plurality of source lines;
a gamma voltage generator configured to generate a plurality of gamma voltages having different voltage levels;
a source driver connected to the plurality of source lines, and configured to generate an output signal corresponding to n-bit data using the plurality of gamma voltages, and transmit the output signal to a corresponding source line of the plurality of source lines; and
a driving controller configured to:
gamma-correct an n-bit input image signal to generate m-bit gamma image data,
select two compensation values corresponding to first low-order bit data of the m-bit gamma image data from among a plurality of compensation values,
interpolate the two compensation values based on a second low-order bit data of the m-bit gamma image data to obtain a final compensation value, and
add the final compensation value to the m-bit gamma image data to generate the n-bit data,

wherein n is a natural number greater than one and m is a natural number greater than n.
