Abstract: The market forecast and researching institutions of the flat panel display especially the Field Emission Display (FED) were introduced. The basic fabrication processes of FED were introduced, including cathode activation technology and thin film sputtering technology. The effects of the cathode activation technology on the enhancement of electron number emitted from the cathode surface were discussed in details. The FED panel was fabricated by using thin film sputtering, screen printing and cathode activation technologies. The cathode of FED prototype was activated with low work function materials. The activation process is lower than the work function of the cathode surface effectively and therefore the electron number increased dramatically emitted from the cathode surface. The prototype thus fabricated could display video images and moving pictures. Its screen brightness and contrast ratio are 300 cd/m2 and 400 respectively. The possible development of FED on its cathode materials and structure, and the overall fabrication technology were also discussed.
