Problems solved by technology

At present, in most display devices, the gate structure is used above the carbon nanotube cathode. The manufacturing process of this control form is relatively simple, and the control effect of the gate structure is significant, but the gate current formed Relatively large, greatly reducing the display brightness of the overall display device

Abstract

The flat panel display includes cathode glass faceplate, anode glass faceplate, and sealed vacuum cavity surrounded by glass frame. There are cathode conductive layer, Nano carbon tubes, and side gridcontrol structure of beveled cathode on the cathode glass faceplate. There are anode conductive layer and phosphor layers prepared on the conductive layer on anode glass faceplate. Structure of supporting wall and attached elements of getter are located between anode glass faceplate and cathode glass faceplate. The invention enhances control function of grid structure greatly, increases emissionarea and emission efficiency of cathode of Nano carbon tubes so as to be in favor of raising display brightness of whole apparatus further. Advantages are: stable and reliable manufacturing procedure,simple technique and structure, and low cost.

Description

technical field [0001] The invention belongs to the fields of flat panel display technology, microelectronic science and technology, vacuum science and technology, and nano science and technology, and relates to device fabrication of flat panel field emission displays, in particular to carbon nanotube cathodes. The device manufacturing aspect of the flat panel field emission display particularly relates to a flat panel display with a grid control structure on the cathode side of an inclined plane and its manufacturing process. Background technique [0002] Carbon nanotubes are a very important nanomaterial with many unique properties, such as unique geometric shape, high aspect ratio and good physical and chemical properties, etc., especially the excellent tip emission makes carbon nanotubes possible to become High-efficiency field-emission electron sources of the future. Using carbon nanotubes as the field emission cold cathode material can obtain a field emission cathode ...
