Abstract:
1. A planar field emission illumination module, comprising: a top substrate, which has a fluorescent powder coating and an anode; a bottom substrate, which comprises a bottom plate, a plurality of cathodes, a plurality of electron emitters on the cathodes respectively, a patterned insulation coating consisting of a plurality of spacers, and one or more gate electrodes as electron-amplification plates on the insulation coating and each gate electrode is supported by two spacers; and a plurality of electron-amplification sets, between the top substrate and the bottom substrate, and each electron-amplification set has the multiple electron-amplification plates; wherein the electron-amplification plates in the electron-amplification sets are spaced at gaps, and formed of a sheet metal on which surface an electron-amplification material is coated, and have a pattern of cross section selected from a group consisting of V shape, U shape, semi-circle shape, arc shape, trapezoid shape, irregular shape, and the combinations thereof.
