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.
