Claim:
1. A method of driving a display panel, comprising: generating a plurality of reference gamma voltages corresponding to a two-dimensional (2D) mode and a plurality of reference gamma voltages corresponding to a three-dimensional (3D) mode based on a mode signal indicating a driving mode of the display panel, wherein the plurality of reference gamma voltages corresponding to the 2D mode is different from the plurality of reference gamma voltages corresponding to the 3D mode; generating a plurality of gamma voltages using the plurality of reference gamma voltages; and generating a plurality of data voltages using the plurality of gamma voltages to drive a plurality of data lines of the display panel, wherein a first black gap between a first 2D black voltage having a first polarity and a second 2D black voltage having a second polarity among the plurality of reference gamma voltages for the 2D mode is greater than a second black gap between a first 3D black voltage having the first polarity and a second 3D black voltage having the second polarity among the plurality of reference gamma voltages for the 3D mode.
