Planar display device with petal-shaped lower-grid controlled cathode structure and its production

Abstract

This is a flat displayer of petaline shape low 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; a supporting wall between the anodic and cathode panel and a getter; on the cathode glass panel are a grid down-lead layer, carbon nanotube and petaline shape low grid structure, which is capable of increasing the control function and efficiency of the grid, so increase the display quality.

Description

Flat panel display with petal-shaped lower grid-controlled cathode structure and manufacturing process thereof Technical field The present invention belongs to the intersecting fields of flat panel display technology, microelectronics science and technology, vacuum science and technology, and nanoscience and technology, and relates to the production of flat-panel field emission displays, and specifically to carbon nanotube cathodes. The content of the device manufacturing of the flat-panel field emission display, in particular, relates to a flat-panel display with a petal-shaped lower gate-controlled cathode structure and its manufacturing process. Background technique The carbon nanotube field emission display technology will shine on the display technology stage. The principle is to use the electrons emitted by the carbon nanotube cold cathode without additional energy. The electron beam is narrow and has high brightness. The bombardment emits visible light. This kind of di...
