Flat-panel display device with ring vertical plane modulated cathode structure and its preparing process

Abstract

The invention relates to a flat-panel display of an annular vertical- plane grid-controlled 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 vertical- plane grid-controlled cathode structure on the cathode glass panel; and it can further improve whole display brightness, resolution and image quality 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 production aspect of the flat panel field emission display particularly relates to a flat panel display with a ring vertical surface type cathode control structure and its manufacturing process. Background technique

[0002] Carbon nanotube field emission display device is a new type of self-luminous flat display device, which not only has the high image display quality of cathode ray tube display, but also has the advantages of low power consumption and ultra-thin type of liquid crystal display, and has excellent Contrast and rich colors, with virtually no viewing angle issues, are considered ideal for next-generation flat-panel displays. It combines the ...
