Optimization Design and Fabrication of Annular Field Emitter for Field Emission Display Panel
With high-effective screen-printing technique, the diode field emission display (FED) panel with carbon nanotube (CNT) as cathode material was fabricated. For improving the field emission properties, the annular field emitter was developed. The bar cathode indium tin oxide (ITO) electrode was formed by the divided ITO film with the photolithography process. After the sintering process, the printed silver slurry was solidified to form the rectangular ring electrode. The prepared CNT paste was printed to form the cold cathode emitter. Field emission characteristics of sealed FED panel were measured, and the emission image was also presented. A series of low-cost manufacture process was employed in the device fabrication course. The fabricated FED panel exhibited better field emission performance and large emission current.
