Abstract:
1. A method for manufacturing a field emission display, comprising: providing a cathode module comprising a plurality of cathode electrodes and a plurality of electron emitters arranged on the cathode electrodes; manufacturing a double-gated structure, comprising: providing an insulating plate; depositing two metallic thin films on two opposite surfaces of the insulating plate respectively; conducting a photolithography process, including partially etching one of the metallic thin films so as to obtain a plurality of mutually parallel strip-shaped gate electrodes; and defining a plurality of through holes which penetrate the gate electrodes, the other metallic thin film and the insulating plate; providing an anode module comprising an anode electrode and a phosphor layer attached on the anode electrode; and assembling the cathode module, the double-gated structure and the anode module so as to form the field emission display.
