  • Patent number: 9018831
    Abstract: A triode-type field emission device and method of manufacturing the same, suitable for use in screen print process of curved or planar substrate, comprising the following steps: firstly, form a cathode and a gate on a cathode substrate at the same time by means of screen printing, and a gap is located between gate and cathode, to avoid short circuit or interference; next, form a hedgehog-shape field emission layer on at least said cathode; then, form a transparent conductive layer and a light emitting layer sequentially on an anode substrate; and finally, dispose cathode substrate and anode substrate in parallel and spaced apart, and package them into a triode-type field emission device. Bias of cathode and gate can be controlled to achieve local adjustment of light. Also, gate may serve as an emitter, to increase field emission efficiency and its service life.

  • Patent number: 8299699
    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.
