Abstract:
A method of driving an electron-emitting device, comprising the steps of:a first measurement step of measuring at least one of an emission current (Ie1) emitted by the electron-emitting device and a device current (If1) flowing through the electron-emitting device, when a voltage (V1) is applied to the electron-emitting device;a second measurement step of measuring at least one of an emission current (Ie2) emitted by the electron-emitting device and a device current (If2) flowing through the electron-emitting device, when the voltage (V1) is applied to the electron-emitting device after said first measurement step; anda voltage application step of applying a voltage (V2) higher than the voltage (V1) to the electron-emitting device, in a case where at least one of the emission current (Ie2) and the device current (If2) is larger than the emission current (Ie1) and the device current (If1), respectively,wherein in said voltage application step, the voltage (V2) is applied so that at least one of the emission current (Ie2) and the device current (If2) becomes closer to the emission current (Ie1) and device current (If1), respectively, of the electron-emitting device.
