Abstract
Disclosed are a digital gamma circuit capable of reducing a chip area and adjusting white color coordinates, and a source driver including the same. The digital gamma circuit may include a digital gamma algorithm for setting a gamma curve for each R, G, or B. Through the digital gamma algorithm, values of X-axis points of the gamma curve may be set, values of Y-axis points of the gamma curve corresponding to the values of the X-axis points may be set, and a value of at least one Y-axis point indicative of white among the values of the Y-axis points may be adjusted by adding an offset value thereto.
