Abstract

The invention relates to a flat-panel display of a tilted grid-controlled concave arc vertebra-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 tilted grid-controlled concave arc vertebra-type cathode structure on the cathode glass panel; and it can raise electron emission efficiency of carbon nanotube and improve display brightness 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 slanted grid-controlled concave-arc-cone cathode structure and its manufacturing process. Background technique [0002] The carbon nanotube cathode field emission display is a matrix display technology device that uses field emission electrons to bombard the phosphor layer to emit light. Its principle is roughly the same as that of the cathode ray tube display. Carbon nanotubes are small tubular structures with curled graphite layers, which can emit a large number of electrons under the action of an applied electric field, and are a cold cathode ma...
