Grid structure of carbon nano-tube field emission display device and manufacturing method thereof

Abstract

This invention relates to a grating structure of a carbon nm tube field emission display device and its preparation method, in which, said grating structure takes a glass substrate as a cathode glass baseboard to cover a cathode electrode on the glass substrate and a dense material film layer on the cathode electrode and cover an insulation medium layer on the dense material layer, an insulation hole is set in the middle of the insulation medium layer, the surface of the carbon nm tube slurry layer is exposed in the hole with the bottom smelt in the dense material film layer, a grating electrode is covered on the top of the insulation medium layer, grating small holes are set in the grating electrode and aligned with the insulation medium hole at the bottom and the cross section of the hole is in a bowl structure of wide up and narrow down.

Description

technical field

[0001] The invention relates to the design of the gate structure of a field emission display, the selection of materials, the design of a manufacturing process flow, and the surface treatment technology of emission materials, and belongs to the technical field of field emission display manufacturing. Background technique

[0002] At present, as a new type of display technology, carbon nanotube field emission display device (CNT-FED) is still far from being marketed, mainly because some technical bottlenecks cannot be effectively resolved. Among them, efficient device structure design and fabrication is a typical problem.

[0003] A cathode substrate with a carbon nanotube array and an anode substrate with a transparent electrode and coated with fluorescent powder can form the simplest field emission display screen of carbon nanotubes with a diode structure, and its manufacturing process is simple. In the field emission display of carbon nanotubes with a diod...
