Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to these embodiments.

[0040] Such as figure 1 , 2 , 3, a sealed vacuum chamber made of cathode panel glass 1, anode panel glass 6 and glass enclosure 10, a carbon nanotube cathode 5 printed on the cathode panel glass 1 and a bridge for controlling carbon nanotube 5 electron emission The grid structure controls the grid 4 , on the anode panel glass 6 there is a photoetched tin indium oxide thin film layer 7 and a phosphor layer 9 prepared on the tin indium oxide thin film layer 7 . A bridge grid structure is made on the cathode panel to control the electron emission of the carbon nanotube cathode, which improves the ability of the carbon nanotube to emit electrons, improves the field emission performance of the display device, and further improves the field emission of the carbon nanotube cathode. While improvin...

Abstract

This invention relates to a three-stage field emission display of a carbon nm tube cathode with a bridge-grating structure and a manufacturing method, among which the display includes a sealing vacuum cavity made up of a cathode panel, an anode panel and a glass surrounding frame, the printed carbon nm tube cathode and a bridge-grating control grid for controlling the electronic emission of the tube are set on the cathode panel, a photo-etched SnIn oxide film layer and a phosphor powder layer are on the film layer on the anode panel, which increases the capability of emitting electrons of carbon nm tubes and improves the field emission performance of display devices.

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...
