Light emitting displayer with small arc mixed silver gating inclined long leaf convex edge strewn cathode structure

Abstract

The invention relates to a light emitting displayer with a small arc mixed silver gating inclined long leaf convex edge strewn cathode structure. The light emitting displayer comprises a vacuum chamber composed of an upper crush-resistant flat tightly closed plate, a lower crush-resistant flat tightly closed plate and a transparent glass frame, getter located in the vacuum chamber, and a rectangular black-wall ancillary element. An anode low-resistance high-transmittance film layer, an anode expanding silver bar layer connected with the anode low-resistance high-transmittance film layer, and a fluorescent powder layer prepared on the anode low-resistance high-transmittance film layer are arranged on the upper crush-resistant flat tightly closed plate. The small arc mixed silver gating inclined long leaf convex edge strewn cathode structure is arranged on the lower crush-resistant flat tightly closed plate. The light emitting displayer has the advantages of being reliable in manufacturing process, excellent in light emitting gray level adjustable performance, large in anode current and high in light emitting brightness.

Description

technical field [0001] The invention belongs to the fields of nanometer science and technology, display technology, vacuum science and technology, integrated circuit science and technology, microelectronics science and technology, and optoelectronic science and technology, and relates to planar field emission luminescent displays The manufacture specifically relates to the manufacture of a planar field emission luminescent display with carbon nanotube cathodes, and in particular to a luminescent display with a small curved arc mixed with silver-gated slanted long fan outer convex edge scattered cathode structure. Background technique [0002] Carbon nanotubes are semiconductor materials with unique properties and have been successfully fabricated as cold cathodes for field emission light-emitting displays. Only relying on the effect of strong external electric field strength, carbon nanotubes can emit a large number of electrons, which also forms the working current of the f...

AI Technical Summary

Problems solved by technology

Because the distance between the cathode and the gate is very close, the fabrication process of these two structures will affect each other during the fabrication process; a little carelessness may cause the carbon nanotube cathode to be unable to manage electrons, which also makes the field Emissive displays completely fail

The current cathode-gate structure is fabricated separately, and the defects of this fabrication mode are obvious

Second, the fabrication of the carbon nanotube layer

Due to the poor structure of the carbon nanotube layer, under the action of the gate voltage, the critical value necessary for the field electron emission of the carbon nanotube cannot be formed at all, and naturally there will be no field emission light-emitting...
