Flat plate display of suspension square cathode type high angle grid control structure and manufacturing process thereof

Abstract

The invention particularly relates to a flat plate display of a suspension square cathode type high angle grid control structure and a manufacturing process thereof. The flat plate display comprises the following components: a sealed vacuum chamber consisting of a cathode glass panel, an anode glass panel and a glass frame; an anode drainage layer, an anode connection layer and an anode covering layer which are arranged on the anode glass panel, and a luminescent layer which is prepared on the anode drainage layer; and an isolator and a getter which are positioned between the anode glass panel and the cathode glass panel. The suspension square cathode type high angle grid control structure comprises a cathode glass panel, a cathode barrier layer, a cathode bottom layer, a cathode connection layer polar enhancement layer, a cathode translation layer, a cathode transition layer, a cathode sacrificial layer, a first blocking layer, a first grid drainage layer, a grid connection layer, a second blocking layer, a second grid drainage layer, a third blocking layer and a carbon nanotube. The flat plate display has the advantages of low cost, simple manufacturing process and stable and reliable manufacturing course.

Description

technical field [0001] The invention belongs to the field of flat panel display technology, the field of vacuum science and technology, and the field of nano science and technology. Manufacturing, in particular to a flat-panel display with a suspended square negative high-angle grid-controlled structure and a manufacturing process thereof. Background technique [0002] With the development of flat panel display technology, flat panel display devices have come into people's field of vision. Using a completely planar device to display images has the superior characteristic that images will not be distorted. Among the current mainstream display devices, liquid crystal displays and plasma displays are the representatives, but each has its own advantages and disadvantages. The field emission display is an excellent display device. It not only retains the advantages of high-quality images of the CRT display, but also overcomes its bulky, bulky and other shortcomings. The combin...

Problems solved by technology

However, in the currently developed three-electrode structure field emission display devices, there are generally defects such as too high gate operating voltage and too large gate current. At the same time, due to the complicated manufacturing process of the gate structure, the gate The requirements for structural materials are also too stringent, resulting in high overall device manufacturing costs. These are unavoidable problems and practical problems that need to be solved urgently

However, there is no satisfactory solution for the fabrication process and structure of the carbon nanotube cathode, and a lot of research and development are still needed.
