Abstract
A double-sided light-emitting field emission device and method of manufacturing same, said device comprising at least two transparent conductive layers, mixed field emission layers, and transparent package device. Wherein, the mixed field emission layer of field emission source and phosphor are utilized directly to serve as anode and cathode alternatively, such that on applying an AC power supply, roles of anode and cathode are changed alternatively along with frequency, hereby forming double-sided light-emitting structure. Therefore, the applications of said double-sided light-emitting field emission device are pretty wide, and having advantages of protecting field emission source, activating field emission source, reducing field emission arcing effect, having conductive phosphor, and raising illumination.
