Electron emission display and method of controlling the same

Abstract

An electron emission display and a method of controlling the same, in which a voltage applied between a cathode electrode and a gate electrode is adjusted according to an image level, includes: a pixel portion having a plurality of electron emission devices formed adjacent to a region where a plurality of data lines intersects a plurality of scan lines; a data driver supplying a data signal corresponding to video data to the plurality of data lines; a scan driver supplying scan signals to the plurality of scan lines in sequence; a power supply supplying power to the data driver and the scan driver; and a voltage level controller controlling a voltage difference between an cathode electrode and a gate electrode of the electron emission device on the basis of an image level corresponding to the video data. With this configuration, a contrast of an image is high in the case of a low image level and a power consumption is limited in the case of a high image level, and an electron emission device is prevented from deterioration.
