Electron emission display device and method of controlling the same

Abstract

An electron emission display device and a method of controlling the same, in which a voltage applied between a cathode electrode and a gate electrode is controlled corresponding to a current in an anode electrode. The electron emission display device includes a display region including a anode electrode, and a plurality of electron emission devices disposed at electron emission regions; a data driver for supplying a data signal corresponding to video data to a plurality of data lines; a scan driver for supplying scan signals to a plurality of scan lines; a power supply for supplying power to the data driver and the scan driver; a current measuring device for measuring a current in the anode electrode; and a voltage level controller for controlling a voltage difference between a cathode electrode and a gate electrode of the electron emission device on a basis of the current.
