Experimental Fabrication of Small Flat-Panel Field Emission Lamp with Printed Carbon Nanotubes as Field Emitters
With effective screen-printing technique, the flat-panel field emission lamp (FPFEL) based on carbon nanotube as cold cathode material was fabricated. The prepared CNT paste was printed on the cathode glass plate to form the field emitter and sealed into the device vacuum room of FPFEL. For improving the display image uniformity, the discrete anode indium tin oxide (ITO) zones method was adopted, and the anode voltage could be applied through the silver anode connecting line for the different anode ITO zones. The anode insulation wall was fabricated to support the anode glass plate, which the deforming of anode glass plate would be avoided. The emission image for the small vacuum-sealed FPFEL with printed carbon nanotube as field emitters was presented. The fully-sealed FPFEL possessed high luminance brightness and better field emission uniformity.
