Abstract

This is a flat displayer of arc low grid multi-faces 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 arc low grid multi-faces structure, which is capable of increasing the efficiency of electron ejection by the nanotube and decreasing the working voltage of the grids.

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 an inverted arc-shaped lower grid-controlled multi-face cathode structure and its manufacturing process. Background technique [0002] With the rapid development of display technology, displays are required to develop in the direction of multi-function, digitalization, and complete flatness. Specifically, modern display devices are meeting the requirements of flatness, high density, high resolution, energy saving, high brightness, and full color , Large-screen flat panel quality system requirements have been rapidly advanced in the direction. Usi...
