Problems solved by technology

In addition, the electron emission of the carbon nanotube cathode needs to be strongly controlled by the grid. The shorter the distance between the grid and the cathode, the greater the electric field strength formed at the top of the carbon nanotube, and the carbon nanotube can More electrons are emitted, but at the same time, it is limited by the insulating properties of the insulating material between the gate and the cathode, and cannot cause electrical breakdown between the two

Abstract

The invention relates to a plate display in coaxial multi-annular cylinder cathode array emission structure and relative production, wherein it comprises an anode glass panel, a cathode glass panel, and a sealing vacuum chamber surrounded by four glass frames; the anode glass panel is arranged with anode conductive layer and a fluorescent powder layer is above the conductive layer; a support wall structure and a gattering additional element are between the anode glass panel and the cathode glass panel; a control grid, a carbon nanometer tube cathode and coaxial multi-annular cylinder cathode array emission structure are arranged on the cathode glass panel. The invention can effectively shorten the distance between grid and cathode, reduce the working voltage, improve the emission area of carbon nanometer tube and improve the display brightness, with lower 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 manufacturing aspect of the flat panel field emission display particularly relates to the device manufacturing and manufacturing process of the carbon nanotube field emission flat panel display with a coaxial multi-circular cylindrical cathode array structure. Background technique [0002] Carbon nanotubes have a small tip radius of curvature, high aspect ratio, extremely high mechanical strength and good physical and chemical properties, which have attracted the attention of many researchers. Under the action of an applied voltage, carbon nanotubes can emit a large number of electrons without additional energy, which is a unique field emission phenomenon. ...
