Abstract

The invention is related to a triple pole field emission display that adopts glass bar as the isolation column between the control grid and positive plate, and adopts sheet mica as insulator between the glass bars, and the glass array through agglomeration as isolation column. It consists of a control grid used to control carbon nanotubes to emit electrons. On the display, there are the positive plates that are photo- etched on the ITO film, the negative plate that is printed carbon nanotubes cathode, and the fluorescent powder layer that is coated on the ITO film.

Description

technical field [0001] The invention belongs to the intersection of vacuum science and technology, microelectronics science and technology and nanometer science and technology, and specifically relates to a glass strip array used as an isolation column between a control grid and an anode plate, and a high-quality mica sheet as the space between the glass strips. The invention discloses a three-pole field emission display using glass strip arrays as isolation columns, which are separated from each other and manufactured by a sintering process, and a manufacturing process thereof. Background technique [0002] At present, for three-pole field emission flat panel displays using carbon nanotubes as cathodes, the anode plate and the control grid need to be separated from each other by a certain distance, so that the electrons emitted from the carbon nanotube cathodes can have sufficient Time and enough distance to accelerate the movement under the action of high anode voltage. H...
