ABSTRACT:
A FED with integrally formed deflection electrode coupled to the electron emitter such that any variation of electron emitter operating voltage is coincidentally impressed on the deflection electrode so as to effectively minimize variations in the emitted electron beam cross-section. In image display devices including FEDs with voltage variations induced at the electron emitter to provide image information, integrally formed deflection electrodes are connected to follow the electron emitter variations so that pixel cross-sections remain substantially invariant under device operation.
