Abstract

This is a flat displayer of triangle shape low grid cathode structure and its production process. It includes a sealed vacuum chamber formed by a anodic glass panel, a cathode glass panel and surrounded glass frame; on the anodic glass panel is a conducting layer coated with fluorescent; a supporting wall between the anodic and cathode panel and a getter; on the cathode glass panel are a grid down-lead layer, carbon nanotube and triangle shape low grid structure, which is capable of increasing the control function and efficiency of the grid, and increasing the electron ejecting area of the nanotube and display brightness.

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 device manufacturing aspect of the flat panel field emission display particularly relates to a flat panel display with a triangular bottom grid-controlled cathode structure and its manufacturing process. Background technique [0002] Carbon nanotubes are a kind of curly graphite layer tubular substance with small tip curvature radius and high aspect ratio, which can emit a large number of electrons under the action of an applied electric field strength, showing good field emission characteristics. Using this principle, the development of field emission flat panel display devices with carbon nanotube cathodes has been carried out. Field emission flat panel display...
