Abstract:
A field ion display device, comprising a fluorescent plate, a field ion emission plate and a microchannel plate for converting an ion emission beam into an electron beam, said field ion emission plate, said microchannel plate and said fluorescent plate are arranged parallel to each other, with gaps there between, said microchannel plate being arranged between the other two plates, and being peripherally sealed with a thin inert gas with pressure 10âˆ’4-10âˆ’5 torr filled inside, wherein X-line electrode system is provided on the inner side of said field ion emission plate, each X-line electrode including a plurality of fine wedge shape lines connected parallel; Y-line electrode system is provided on the side of said microchannel plate facing said field ion emission plate, an accelerating electrode is provided on the other side of said microchannel plate, each crossing point of said Y-line electrodes on said microchannel plate and said X-line electrode on said field ion emission plate, is an addressing point, on those addressing points there are many microchannel holes passing through said microchannel plate to simulate multi-fold secondary electron emission; on the inner side of said fluorescent plate, facing every addressing point high voltage fluorescent pixels are provided, on which a thin aluminum film is deposited as a screen electrode.
