Abstract
A double-faced field emission display device includes two parallel fluorescent screens (') and an electron emission structure () located between the fluorescent screens. Each fluorescent screen includes a transparent substrate (′) with an anode plate (′) and coplanar fluorescent layers (′) formed at an inner surface of the transparent substrate. The electron emission structure includes an opaque insulative substrate () with cathode plates (′), electron emitters (′) and grid plates (′) formed at each of opposite surfaces () thereof. Symmetrically opposite pairs of same electrodes are electrically interconnected so that the fluorescent screens can simultaneous display a same image. Only a single driving system is needed to achieve the simultaneous display.
