Abstract

The invention relates to a light-emitting display with a three-wire crossing angle support silver arc gating all-pit surface and curved bottom cathode structure. The light-emitting display comprises a vacuum chamber, a getter and a thin blanking wall attachment element, wherein the vacuum chamber comprises a back vacuum pressure-resistant rigid plate, a front vacuum pressure-resistant rigid plate and a transparent glass frame; the front vacuum pressure-resistant rigid plate is provided with a thin anodic oxide transmitting square layer, an anodic long extension silver white layer connected with the thin anodic oxide transmitting square layer, and a fluorescent powder layer prepared on the thin anodic oxide transmitting square layer; the back vacuum pressure-resistant rigid plate is provided with the three-wire crossing angle support silver arc gating all-pit surface and curved bottom cathode structure; and the getter and the thin blanking wall attachment element are located in the vacuum chamber. The light-emitting display has the advantages of being high in anode current, excellent in light-emitting gray regulating performance, reliable in manufacturing process, short in response time and high in light-emitting brightness.

Description

technical field [0001] The present invention belongs to the fields of display technology, nanometer science and technology, integrated circuit science and technology, microelectronics science and technology, vacuum 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 a carbon nanotube cathode, and in particular to a luminescent display with a three-line cross angle-supported silver-arc-gated full-pit surface curved-bottom cathode structure and its manufacturing process. Background technique [0002] Carbon nanotubes are a kind of semiconductor material, which can emit electrons in a vacuum environment only by applying a high electric field strength. On the basis of making full use of this phenomenon, carbon nanotubes have been successfully applied in field emission light-emitting displays and becom...
