Problems solved by technology

At present, the materials used by various manufacturing companies or research institutions to make control grids are different, but most of them use special special materials and special manufacturing processes, which brings a series of problems. For example: the cost of device manufacturing is high; the manufacturing process is complicated; the manufacturing process conditions are too harsh, and large-area manufacturing cannot be carried out, etc.

Abstract

The invention relates to a field emission display with a triode structure of a carbon nanotube cathode with a bridge-grid structure and its manufacturing process. The display includes a sealed vacuum chamber composed of a cathode panel, an anode panel and a glass enclosure. There are printed carbon nanotube cathodes and bridge grid structure control grids to control the electron emission of carbon nanotubes. There are photolithographic tin indium oxide thin film layers on the anode panel and phosphor layers prepared on the tin indium oxide thin film layers. , a bridge grid structure is made on the cathode panel, which is used to control the electron emission of the carbon nanotube cathode, improves the ability of the carbon nanotube to emit electrons, and improves the field emission performance of the display device. It has the advantages of low cost and stable and reliable production process.

Description

technical field [0001] The invention belongs to the fields of vacuum science and technology, microelectronics technology, planar display technology and nanometer science and technology, and relates to the manufacture of devices for field emission flat panel displays, in particular to devices for field emission displays with a triode structure of carbon nanotube cathodes The content of production, in particular, relates to the production process of field emission flat display devices with bridge grid structure, carbon nanotube cathode, and triode structure. Background technique [0002] Carbon nanotubes are a special cathode material that can emit a large number of electrons only under the action of an external voltage to form field emission electrons, which is determined by its special shape. For field emission flat panel display devices using carbon nanotubes as cathode materials, in order to reduce production costs to the greatest extent and reduce the operating voltage of...
