P-125: A Novel 4.75 inch CNT-FED with Sturdy Metal Plate as Spacer

Abstract

We have successfully fabricated 4.75‐inch CNT‐FED with sturdy metal plates as spacer. The metal plates were etched numerous holes and coated oxide to supply high efficient passage for electrons. We observed that several metal plates not only helped cathode to shield high electric field from anode but also supplied sturdy spacer between cathode and anode. In this work, a uniformity lighting image is obtained and capable of being applied to large‐area CNT‐FEDs.
