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 field of vacuum science and technology, microelectronics science and technology and nano science and technology, and specifically relates to a glass strip array as the isolation column between the control grid and the anode plate, and a high-quality mica sheet as the spacer between the glass strips. The invention relates to a three-pole field emission display with glass strip arrays as spacer pillars, which is mutually spaced and manufactured by sintering technology, and its manufacturing technology. Background technique [0002] At present, for a field emission flat panel display with a triode structure using carbon nanotubes as a cathode, 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 cathode can have enough The time and sufficient distance are used to accelerate the movement under the action of the high v...
