Abstract

The invention relates to a flat panel display with a suspended strip cathode array structure and its manufacturing process, which comprises a sealed vacuum chamber composed of an anode glass panel, a cathode glass panel and surrounding glass frames; an anode conductive layer is arranged on the anode glass panel and Phosphor layer prepared on top of the anode conductive layer; support wall structure and getter attachment elements between the anode glass panel and the cathode glass panel; control grid, carbon nanotubes, and suspended strip cathode array on the cathode glass panel structure; it can make full use of the phenomenon of emitting a large number of electrons at the edge position, which improves the electron emission efficiency of carbon nanotubes; while highly integrating the grid and the cathode, it strengthens the control efficiency and control function of the grid, which is conducive to further improving The image display quality of the device has the advantages of stable and reliable manufacturing process, simple manufacturing process, low manufacturing cost and simple structure.

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 content of device fabrication of flat panel field emission display, especially relates to the fabrication of flat panel display with a suspended strip cathode array structure and its fabrication process. Background technique [0002] Carbon nanotubes are hollow tubular carbon structures formed by curling thin coaxial graphite layers. They have unique geometric shapes, high mechanical strength, good electrical conductivity, and the ability to change according to their helicity and diameter. Electrical properties and many other special physical properties, so once the discovery of carbon nanotubes, it immediately attracted great attention. Since carbon nanotubes ha...
