The invention relates to a flat-panel display of a tilted lower grid-controlled flat 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; and grid lead layer, carbon nanotube and tilted lower grid-controlled flat cathode structure on the cathode glass panel; supporting wall structure and degassing agent auxiliary component between the anode glass panel and cathode glass panel; and it can improve whole display brightness and resolution 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, especially relates to a flat panel display with an oblique downward gate-controlled flat cathode structure and its manufacturing process. Background technique [0002] In the past few years, display components are accelerating the process of flattening, and carbon nanotube cathode field emission display is a new type of flat display device that has emerged as the times require. Its working principle is similar to that of traditional cathode ray tube displays, so this display fully retains It not only has the characteristics of high-definition display image quality of cathode ray tube display, bu...
