Panel display device with short circuit prevention cathodic protection structure and its production technique

Abstract

The invention relates to a plate display in short-circuit prevent cathode protection structure and relative production, wherein it comprises an anode glass panel, a cathode glass panel, and a sealing vacuum chamber surrounded by four glass frames; the anode glass panel is arranged with anode conductive layer and a fluorescent powder layer is above the conductive layer; a support wall structure and a gattering additional element are between the anode glass panel and the cathode glass panel; a control grid, a carbon nanometer tube cathode and short-circuit prevent cathode protection structure are arranged on the cathode glass panel. The invention can effectively avoid short circuit between control grid can cathode, to improve the production success and reduce the working voltage, with lower cost and simple structure.

Description

technical field [0001] The present invention belongs to the fields of vacuum science and technology, microelectronic science and technology, plane display technology and nanometer science and technology, and relates to the fabrication of devices for flat panel field emission displays, in particular to flat panel field emission of carbon nanotube cathodes The content of the device production of the display is particularly related to the device production and the production process of the flat field emission display with a carbon nanotube cathode with an anti-short circuit cathodic protection structure. Background technique [0002] Carbon nanotubes have a small tip radius of curvature, high aspect ratio, and good physical and chemical properties, which have attracted the attention of many researchers. When an appropriate voltage is applied to the top surface of the carbon nanotube, the carbon nanotube will emit a large number of electrons without applying additional energy ag...

Problems solved by technology

However, this has brought new problems to the manufacturing process of the device. On the one hand, the carbon nanotube cathode material is relatively fragile, and any damage to the carbon nanotube cathode during the device manufacturing process will reduce its field. Therefore, effective measures must be taken to protect the carbon nanotube cathode; on the other hand, although the distance between the control grid and the carbon nanotube cathode is very close, the two are electrically isolated from each other. It can make the two connected, otherwise the practical significance of the control gate structure will be lost
