Abstract

This is a flat displayer of V shape overlaping 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; a supporting wall between the anodic and cathode panel and a getter; on the cathode glass panel are a grid down-lead layer, carbon nanotube and V shape overlapping cathode structure, which is capable of increasing the efficiency and area of electron ejection by the nanotube and the display quality.

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 the flat panel field emission display particularly relates to a flat panel display with a multi-curved cathode structure with inverted sharp angles overlapping and its manufacturing process. Background technique [0002] Carbon nanotube cathode field emission display is a new type of flat display device, and its application fields are very broad, such as large-screen wall-mounted color TVs in various places, display screens in conference rooms, studios or command centers, stations or docks Outdoor large billboards, military helmet-type goggles, etc. Carbon nanotubes are small, graphite-layered, tubular substances with a high aspect ...
