Abstract

The invention relates to a flat-panel display of a forked side bottom grid-controlled 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 forked side bottom grid-controlled structure on the cathode glass panel; and it can further increase operating current of anode and reduce operating voltage of grid structure, 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 particularly relates to a flat panel display with a bifurcated side bottom gate control structure and its manufacturing process. Background technique [0002] Carbon nanotube field emission display is a new type of flat display technology developed by using the principle of carbon nanotube cathode field electron emission, which combines the high image quality characteristics of traditional cathode ray tube display. This display has the characteristics of self-illumination, does not require a backlight source, and can produce high brightness similar to that of a cathode ray tube display at a lower...
