Auxiliary interconnection in special-shaped arcs Silver-gated oblique hooks Cathode structure light-emitting display with concave tire surface

Abstract

The invention relates to a light-emitting display with a special-shaped arc internal auxiliary interconnect silver gate control oblique hook concave tread cathode structure. The light-emitting display comprises a vacuum chamber formed by an upper compressive flat white glass cover plate, a lower compressive flat white glass cover plate and a transparent glass frame, wherein the upper compressive flat white glass cover plate is provided with an anodic oxide transparent square film layer, an anode extending wide-curved silver layer connected with the anodic oxide transparent square film layer, and a fluorescent powder layer prepared on the anodic oxide transparent square film layer; the special-shaped arc internal auxiliary interconnect silver gate control oblique hook concave tread cathode structure is arranged on the lower compressive flat white glass cover plate; and a getter and a hidden support column auxiliary component are arranged in the vacuum chamber. The light-emitting display has the advantages of being excellent in light-emitting brightness adjustability, stable in manufacturing process, high in brightness, short in response time and high in anode current.

Description

technical field [0001] The present invention belongs to the fields of display technology, nanometer science and technology, optoelectronic science and technology, microelectronics science and technology, integrated circuit science and technology, and vacuum science and technology, and relates to a flat field emission display The manufacture specifically relates to the manufacture of a planar field emission luminescent display of a carbon nanotube cathode, and particularly relates to a display and a manufacturing process of a luminescent display with an auxiliary interconnected silver-gated oblique hook concave tread cathode structure in a special-shaped arc. Background technique [0002] Carbon nanotubes are a very good source of cold cathode electrons. In a vacuum environment, they can continuously provide cathode electrons for the field emission luminescence display in the form of "field emission", thus forming the necessary conditions for the normal operation of the field ...

Problems solved by technology

Second, the integrated fabrication of carbon nanotube cathodes and gates

When making the subsequent structure, it is easy to cause damage to the previous structure; in addition, the carbon nanotube layer is thin-layered, which is very easy to be damaged and polluted, so it is necessary to integrate the two structures of the carbon nanotube cathode and gate production, the degree of their mutual influence must be reduced, or the mutual influence between the two must be completely eliminated

Once the carbon nanotube layer is damaged or polluted, the ability to emit electrons decreases, which will cause a complete failure of the field emission display.

Third, the production of carbon nanotube layers

In addition, the production cost of the field emission light-emitting display is also one of the things that must be taken into account

Too expensive field emission luminescent displays cannot meet the actual product needs of the display technology market
