Problems solved by technology

At present, most of the flat panel display devices have chosen a structure in which the gate structure is located above the cathode of the carbon nanotube. The strong control effect of the gate structure is obvious, and the manufacturing process is relatively simple, but the formed gate current is relatively large, and the work The voltage is a bit high, and the requirements for the production materials are relatively strict, which is its disadvantage

Abstract

Present invention relates to flat plate display having fork finger type duplication gate structure and making technology. It contains sealed vacuum cavity constructed from cathode panel, anode panel and around glass enclose, cathode panel having carbon nanotube cathode for emitting electron, anode panel having photo etched anode conducting layer and phosphor powder layer, support wall structure getter element. Emission surface emission surface has fork finger type duplication gate structure, at the same time focusing control electrode having very strong retarding effect to electron beam grid and carbon nanotube cathode presenting fork finger type structure having strong control action to carbon nanotube cathodal electron emission. Said invention has steady reliable manufacturing process, simple technology, low cost, and simple structure etc advantages.

Description

technical field [0001] The invention belongs to the fields of plane display technology, microelectronic science and technology, vacuum science and technology, and nano science and technology, and relates to the manufacture of flat panel field emission displays, in particular to flat panels for carbon nanotube cathodes. The content of device fabrication of field emission display, especially related to the fabrication process of field emission flat panel display device with interdigitated double gate structure and carbon nanotube cathode. Background technique [0002] With its advantages of high definition, flat panel, small thickness, light weight, and no electromagnetic radiation, half-panel display has become a hot spot that people pay attention to, and it heralds the development direction of display technology. The planar field emission display device made of carbon nanotubes as the cathode material is a new type of flat panel device, which has unique features such as wide...
