Abstract

This is a flat displayer of arrow shape grid cathode structure and its production process. It includes a sealed vacuum chamber formed by a anodic glass panel, a cathode glass panel and surrounded glass frame; on the anodic glass panel is a conducting layer coated with fluorescent; on the cathode glass panel are a grid down-lead layer, carbon nanotube and arrow shape grid structure; a supporting wall between the anodic and cathode panel and a getter; which is capable of increasing electron ejecting amount and efficiency of the nanotube and decreasing the working voltage of the rid and increasing the display brightness.

Description

technical field [0001] The invention belongs to the fields of flat panel display technology, microelectronic science and technology, vacuum science and technology, and nano science and technology, and relates to device fabrication of flat panel field emission displays, in particular to carbon nanotube cathodes. The device manufacturing aspect of flat panel field emission display, in particular relates to a flat panel display with an arrow-type grid-controlled cathode structure and its manufacturing process. Background technique [0002] Carbon nanotubes have a small tip curvature radius and a high aspect ratio, and can emit a large amount of electrons without additional energy under the action of an applied voltage, so they have very good field emission performance and can be used as an electron source in Field emission display devices. Field emission displays made of carbon nanotubes as cathode materials make full use of the low conduction electric field, high emission cur...
