发明名称 Procedures and apparatus for turning-on and turning-off elements within a field emission display device
摘要 A method of removing contaminant particles in newly fabricated field emission displays. According to one embodiment of the present invention, contaminant particles are removed by a conditioning process which includes the steps of: a) driving a anode of a field emission display (FED) to a predetermined voltage; b) slowly increasing an emission current of the FED after the anode has reached the predetermined voltage; and c) providing an ion-trapping device for catching the ions and particles knocked off, or otherwise released, by emitted electrons. In this embodiment, by driving the anode to the predetermined voltage and by slowly increasing the emission current of the FED, contaminant particles are effectively removed without damaging the FED. The present invention also provides a method of operating FEDs to prevent gate-to-emitter current during turn-on and turn-off. In this embodiment, the method comprises the steps of: a) enabling the anode display screen; and, b) enabling the electron-emitters after the anode display screen is enabled. In this embodiment, by allowing sufficient time for the anode display screen to reach a predetermined voltage before the emitter is enabled, the emitted electrons will be attracted to the anode.
