Abstract

The invention relates to a flat-panel display of an annular-belt grid-controlled cathode structure and the making process thereof, comprising: sealed vacuum cavity composed of anode glass panel, cathode glass panel, and peripheral glass frame; anode conducting layer on the anode glass panel and fluorescent powder layer prepared on the anode conducting layer; supporting wall structure and degassing agent auxiliary component between the anode glass panel and cathode glass panel; and grid lead layer, carbon nanotube and annular-belt grid-controlled cathode structure on the cathode glass panel; and it can further raise electron emission efficiency of carbon nanotube and helps to improve whole display brightness and has advantages of stable and reliable making course, simple making process, low making cost, and simple structure.

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 production aspect of the flat panel field emission display, especially relates to a flat panel display with a gate-controlled emission structure under the ring band and its manufacturing process. Background technique [0002] Carbon nanotubes are a substance with a graphite layer curl structure in the shape of a hollow tube. It has a small tip curvature radius and a high aspect ratio. It can emit a large number of electrons under the action of an applied electric field, forming a cold field emission phenomenon. It is an excellent cold cathode material. Using this property of carbon nanotubes, the device development of field emission flat panel display was ...
