Problems solved by technology

[0003] At present, most display devices adopt a control mode in which the gate structure is located above the carbon nanotube cathode structure. The manufacturing process of this structure is simple, and the control function of the gate is relatively significant, but the formed gate current is relatively large. , the gate voltage remains high, which is the disadvantage of

Abstract

This invention relates to a flat display of a cross cathode emission structure and its process method including a sealing vacuum cavity composed of an anode glass panel, a cathode panel and a surrounding glass frame, in which, an anode conduction layer is set on the anode glass panel and a fluorescent powder layer is set on the anode conduction layer, a grid lead layer, carbon nm tube and a cross needle cathode emission structure are set on he cathode glass panel, a supporting wall structure and a getter are set between the anode glass panel and the cathode glass panel to strengthen the control function of the grid structure and increase electronic emission efficiency of carbon nm tube cathode.

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 cross-tip cathode emission structure and its manufacturing process. Background technique [0002] Carbon nanotubes have a small tip curvature radius, high aspect ratio, and can emit a large number of electrons under the action of an applied electric field strength, which is a very good cold cathode material. Using carbon nanotubes as field emission cathode materials can make field emission flat panel displays thinner, brighter and clearer. The field emission display with carbon nanotube cathode is a new type of flat panel display device, which ...
