Abstract

This is a flat displayer of step shape side 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; 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 step shape side grid structure, which is capable of decreasing working voltage of the grid and increasing the control function and efficiency.

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, especially relates to a flat panel display with a stepped side grid-controlled cathode emission structure and its manufacturing process. Background technique [0002] The carbon nanotube field emission display is a new type of flat panel display device developed based on the cathode ray tube display technology and made using the field emission principle of the carbon nanotube cathode. The cathode array is composed of thousands of micro-carbon Nanotube emission source composition. This kind of display takes into account many advantages of both cathode ray tube display and liquid crystal display,...
