Abstract
A triode field emission device using a field emission material and a driving method thereof are provided. In this device, gate electrodes serving to take electrons out of a field emission material on cathodes are installed on a substrate below the cathodes, so that the manufacture of the device is easy. Also, electrons emitted from the field emission material are controlled by controlling gate voltage.
