Abstract
A display apparatus includes a display panel and a source driver including a digital-to-analog converter configured to map image data to gamma voltages, obtained through voltage division between a high-level gamma voltage and a low-level gamma voltage, to generate a data voltage and output the data voltage to a data line of the display panel, wherein a voltage difference between the high-level gamma voltage and the low-level gamma voltage is different at a first time and a second time in one frame.
