Abstract
A planar field emission illumination module includes a top substrate, a bottom substrate, and a plurality of electron-amplification sets located between the top substrate and the bottom substrate. Each electron-amplification set has multiple electron-amplification plates spaced at gaps, which are formed of a metal and coated with an electron-amplification material on the surfaces. The cross section of each electron amplification plate can be V-shaped, U-shaped, semi-circular, arc-shaped, trapezoid, irregular, and the combination thereof. The planar field emission illumination module can focus the electrons and regulate the distribution of the electrons effectively. Hence, the planar field emission illumination module can provide a flat light source with illumination uniformity and high brightness.
