Abstract

A display driving circuit may include a source driver that includes a decoder circuit and a buffer circuit. The decoder circuit selects a first gamma voltage and a second gamma voltage among a plurality of gamma voltages based on pixel data, and selects a third gamma voltage different from the first and second gamma voltages among the plurality of gamma voltages. The buffer circuit interpolates between the first and second gamma voltages to output a first target voltage, and steps up or steps down a source voltage formed on the source line to the first target voltage. The buffer circuit includes a fast slew circuit that compares the first source voltage with the third gamma voltage to adjust slew rate of the first source voltage.
