An electron emission display device and a control method thereof, which previously store variable voltage information according to a drive time and/or a size of frame data, and maintain current amount constant without measuring an electric current at the driving time of a real screen in order to prevent a degradation of a pixel are disclosed. A pixel portion includes a plurality of scan lines and a plurality of data lines, and an anode electrode is over an entire region of the pixel portion. A data driver transfers a data signal to the data lines. A scan driver sequentially transfers a scan signal to the scan lines. A power supply unit supplies a electric drive source to the data driver and the scan driver. A controller stores variable voltage information corresponding to a drive time and for maintaining an electric current flowing through the anode electrode constant based on the stored variable voltage information.
