Abstract

The invention relates to a flat-panel display with an integrated stepped groove grid structure and its manufacturing process. The flat-panel display includes a sealed vacuum chamber composed of a cathode glass panel, an anode glass panel and surrounding glass frames. Anode electrode layer with phosphor layer printed on the anode electrode layer, grid conductive layer for controlling electron emission and grown carbon nanotube cathode, support wall structure and getter accessory components with integrated steps on the cathode panel The slot-shaped groove gate structure makes full use of the good field emission characteristics and edge field emission enhancement effect of the carbon nanotubes prepared by the direct growth method to reduce the operating voltage of the device, and also integrates the gate and cathode highly. The manufacturing success rate of the overall device is improved, and the manufacturing process is stable and reliable, the manufacturing process is simple, the manufacturing cost is low, and the structure is simple.

Description

technical field [0001] The invention belongs to the fields of plane display technology, microelectronic science and technology, vacuum science and technology, and nano science and technology, and relates to the manufacture of flat panel field emission displays, in particular to flat panels for carbon nanotube cathodes. The content of device fabrication of field emission display, especially relates to the fabrication process of field emission flat panel display device with integrated stepped groove gate structure and carbon nanotube cathode. Background technique [0002] Carbon nanotube is a coaxial tubular substance that can emit a large number of electrons under the action of an applied voltage. It has a small tip curvature radius, high aspect ratio, good field emission characteristics and excellent physical and chemical stability. Sex, is a very good cold cathode emission material, has attracted the attention of many researchers. At present, the preparation methods for ca...
