Abstract

The invention relates to a flat-panel display of a sharp-angled lower 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 sharp-angled lower grid-controlled cathode structure on the cathode glass panel; and it can effectively reduce operating voltage of grid structure and raise electron emission efficiency of carbon nanotube 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 field emission display, especially relates to a flat panel display with a gate-controlled cathode structure at a sharp corner and its manufacturing process. Background technique [0002] Carbon nanotube field emission flat panel display is a display that uses the number of electrons emitted by carbon nanotube cold cathode to bombard the phosphor layer to emit visible light. It is very similar to cathode ray tube display, and its basic working principle is the same, so sometimes field emission The launch display became a flat CRT. Field emission display technology can combine the brightness and clarity of cathode ray tube di...
