Display device and source line driving method thereof

Abstract

A display device for generating gamma voltages for driving source lines and a source line driving method thereof are disclosed. The display device includes a plurality of gamma generation units configured to generate gamma voltages corresponding to respective colors, a selection unit configured to select gamma voltages corresponding to any one color from among the gamma voltages generated by the plurality of gamma generation units and to output the gamma voltages to a common line, a decoding unit configured to decode the gamma voltages output to the common line, and an output unit configured to buffer the signals decoded by the decoding unit and to output source line driving signals. Thus, it is possible to reduce the number of lines for transferring the gamma voltages.

Dependencies are inferred from the claim text.
