Fabrication Research and Property of Double Cold Cathode for the Field Emission Display Panel
With the precise photolithography process and simple screen-printing technique, the double cold cathode structure was fabricated on the cathode plate. The indium tin oxide (ITO) film coated over the cathode plate surface was etched to form bar ITO stripes, which was used as the cathode electrode. The one ITO group was composed of two parallel bar ITO stripes, on which the screen-printed carbon nanotube paste was employed to form the field emitter. The covering layer was also fabricated by the solidified insulation slurry with the pre-determined patterns. The phosphor prepared on the anode plate was utilized to form the panel image. The sealed field emission display panel with double cold cathode structure showed high panel luminous brightness, better field emission characteristics and good emission uniformity.
