Abstract:
1. A triode-type field emission device manufacturing method, comprising following steps: providing a cathode substrate; forming at least a patterned cathode and two patterned gate on said cathode substrate by means of screen printing, and two said gates are located respectively on both sides of said cathode with said gap between each of two said gates and said cathode; applying a field emission paste on at least said cathode through said screen printing, and then undergoing high temperature sinter, so that a hedgehog-shape field emission layer is formed on said cathode, and an emission surface of said hedgehog-shape field emission layer is higher than top surface of said gates; providing an anode substrate, to form a transparent conductive layer thereon, then screen printing a light emission layer on said transparent conductive layer, and then performing sinter; and disposing said cathode substrate and said anode substrate in parallel and spaced apart, to package them into a triode-type field emission device.
