초록
Provided is a field emission device having a simple structure and capable of pulse driving and local dimming. The field emission device turns a current flowing from each cathode electrode block on or off in response to a switching control signal having a very low voltage ranging from 0 to 5 V while a constant voltage is applied to an anode electrode and a gate electrode to control a field emission current. Compared with a conventional field emission device, the field emission device having a simple structure is capable of pulse driving and local dimming without using a separate pulse driving high voltage power source.
