Flat-board display of arc-shape grid controlled array structure and mfg. process

Abstract

The flat panel display includes cathode glass faceplate, anode glass faceplate, and sealed vacuum cavity surrounded by glass frame. There are cathode conductive layer, Nano carbon tubes, and arc type structure of grid electrode control array on the cathode glass faceplate. There are anode conductive layer and phosphor layers prepared on the conductive layer on anode glass faceplate. Structure of supporting wall and attached elements of getter are located between anode glass faceplate and cathode glass faceplate. The invention shortens gap between structure of grid electrode and structure of cathode of Nano carbon tubes further, reduces working voltage of grid electrode structure, and enhances control function of grid electrode so as to be in favor of raising display brightness of apparatus further. Advantages are: stable and reliable manufacturing procedure, simple technique and structure, and low cost.

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 arc-shaped grid control array structure and its manufacturing process. Background technique [0002] In recent years, carbon nanotubes have been widely used as field emission cathode materials. Carbon nanotubes have a small tip curvature radius, high aspect ratio and good field emission properties, which are very suitable for use as cold cathode materials and have great application potential in vacuum display technology. The field emission flat panel display made of carbon nanotubes as the cathode material is a new type of flat display device,...

AI Technical Summary

Problems solved by technology

At present, in most display devices, the gate is located above the carbon nanotube cathode. The manufacturing process of this control form is simple, and the control function of the gate is relatively significant, but the requirements for the production materials are very high. The formed gate current is relatively large, which is not conducive to further improving the display brightness of the device

In addition, due to the constraints of material insulation performance and manufacturing reliability, the distance between the gate structure and the carbon nanotube cathode structure cannot be further reduced, which also results in high gate operating voltage. main reason
