Problems solved by technology

At present, in most of the carbon nanotube cathode field emission display devices, the control mode in which the gate structure is located above the carbon nanotube cathode structure is adopted. The gate control function of this structure is more significant, and the brightness of the display device It is relatively high, and the display effect is relatively good, but its gate operating voltage remains high, which is far from meeting the quality system requirements of low-voltage flat panel display devices, which still needs further improvement
Then, reducing the distance between the grid structure and the carbon nanotube cathode structure as much as possible seems to be the most direct and effective method, but it is also subject to factors such as the insulation level of the insulating material, the manufacturing process of the insulating material, etc. limits

Abstract

This is a flat displayer of star shape grid cathode structure and its production process. It includes a sealed vacuum chamber formed by a anodic glass panel, a cathode glass panel and surrounded glass frame; on the anodic glass panel is a conducting layer coated with fluorescent; on the cathode glass panel are a grid down-lead layer, carbon nanotube and star shape grid structure; a supporting wall between the anodic and cathode panel and a getter; which is capable of increasing electron ejecting efficiency of the nanotube and decreasing the working voltage of the rid and increasing the display quality.

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 an explosive star cathode structure and its manufacturing process. Background technique [0002] The field emission flat panel display is a new type of flat panel display device, which makes full use of the field emission principle of the carbon nanotube cathode and combines the light emitting mechanism of the cathode ray tube display. When the power is turned on, the electrons directly excite the phosphors that need to emit light, thus emitting visible light. The result is a very thin screen that can display the same high-quality display images as ...
