Abstract
The present invention provides a field emission device driven with a high voltage. The field emission device of the present invention includes a resistor connected between a gate electrode and an external terminal to prevent a leakage current by an electrical connection between the gate electrode and the emitter. Therefore, the power consumption of the device is decreased and the operating characteristic of the device is improved.
Claims5
A field emission device comprising:
- an emitter having a tip shape for emitting electrons;
- a switching means, connected to said emitter, for selectively supplying current to said emitter;
- a gate electrode formed around said emitter, high voltage being applied to said gate electrode in order to emit electrons from said emitter;
- an anode positioned above said gate electrode and said emitter;
- and
- a resistance element, connected between said gate electrode and a gate terminal, for maintaining voltage difference between said emitter and said gate electrode.
