Abstract
An Electron Emission Display (EED) with decreased signal distortion has a data driver to convert data driving signals into display data signals having predetermined data voltage levels and to output the display data signals to data electrode lines. A method of driving the EED includes supplying an auxiliary voltage to the data electrode lines during blanking periods according to subsequent data and supplying the display data signals during active periods between the blanking periods.
