Abstract

This invention relates to a panel display with an umbrella grating array structure and its process technology, in which, the display includes a sealed vacuum cavity composed of a cathode panel, an anode panel and surrounding glasses, a photoetched anode conduction layer and a fluorescence powder layer on the conduction layer, a wall supporting structure and getter elements, in which, an umbrella grating array structure is prepared on the cathode panel and the control to electronic emission of the cathode is strengthened on the basis of fine field emission property of the cathode to reduce the working voltage of the device and increase its emission efficiency.

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 display device with umbrella grid array structure and carbon nanotube cathode. Background technique [0002] Carbon nanotube is a coaxial tubular substance that can emit a large number of electrons under the action of an applied voltage. It has a small tip curvature radius, high aspect ratio, good field emission characteristics and excellent physical and chemical stability. Sex, is a very good cold cathode emission material, has attracted the attention of many researchers. The flat panel display using carbon nanotubes as the cathod...
