Abstract

The invention relates to a flat-panel display of an annular grid-controlled valley mouth-type cathode structure and the making process thereof, comprising: sealed vacuum cavity composed of anode glass panel, cathode glass panel, and peripheral glass frame; anode conducting layer on the anode glass panel and fluorescent powder layer prepared on the anode conducting layer; supporting wall structure and degassing agent auxiliary component between the anode glass panel and cathode glass panel; and grid lead layer, carbon nanotube and annular grid-controlled valley mouth-type cathode structure on the cathode glass panel; and it can further improve whole displayed image quality and reduce operating voltage of grid, and has advantages of stable and reliable making course, simple making process, low making cost, and simple structure.

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 relates to a flat panel display with a ring-grid-controlled valley-mouth cathode structure and its manufacturing process. Background technique [0002] Carbon nanotube field emission display is a new type of flat panel display device, known as the ideal flat panel display in the future. This kind of display has good performance characteristics such as high resolution, high brightness, high luminous efficiency, wide viewing angle, large working temperature range, thinness, bright colors and clear images, and fast response speed. It can be widely used in mobile phones, flat wall mounts, etc. Vario...
