<p>A cold-cathode field emission device controls electron emission by using a current source (101) coupled to the emitter (102). The open circuit oltage of the current source (101) is less than the voltage at which the FED would emit electrons. Application of an accelerating potential (105) on the gate (103) enables electron emission. Electron emission from the FED is governed by the current source (101).</p> |
