Problems solved by technology

[0003] In the carbon nanotube cathode field emission display device with a triode structure, the gate structure is used to directly control the important control elements of the carbon nanotube cathode electron emission, but due to the addition of the gate structure, the overall device fabrication is more complicated
In view of the high working voltage of the gate, the low brightness of the device display, and the low emission efficiency of the carbon nanotube cathode, it needs to be seriously resolved.

Abstract

This is a flat displayer of step shape concave low grid cathode structure and its production process. It includes a sealed vacuum chamber formed by a anodic glass panel, a cathode glass panel and surrounded glass frame; on the anodic glass panel is a conducting layer coated with fluorescent; a supporting wall between the anodic and cathode panel and a getter; on the cathode glass panel are a grid down-lead layer, carbon nanotube and step shape concave low grid structure, which is capable of increasing the display quality and decreasing working voltage of the grid.

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 recessed lower gate-controlled stepped cathode structure and its manufacturing process. Background technique [0002] Carbon nanotubes have a small tip curvature radius. Under the action of an applied voltage, the electric field strength near the cathode tip of carbon nanotubes is very concentrated, forcing carbon nanotubes to emit a large number of electrons without additional energy, that is, cold field emission. Phenomenon. Because carbon nanotubes have good field emission properties, they can be used as electron sources in field emission di...
