Abstract

The flat panel display includes cathode glass faceplate, anode glass faceplate, and sealed vacuum cavity surrounded by glass frame. There are cathode conductive layer, Nano carbon tubes, and polyline grid control structure on the cathode glass faceplate. There are anode conductive layer and phosphor layers prepared on the conductive layer on anode glass faceplate. Structure of supporting wall and attached elements of getter are located between anode glass faceplate and cathode glass faceplate. The invention enhances control function of grid structure further, increases emission efficiency of cathode of Nano carbon tubes so as to be in favor of raising resolution and image quality of whole apparatus further. Advantages are: stable and reliable manufacturing procedure, simple technique and structure, and low cost.

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 field emission display, especially relates to a flat panel display with zigzag grid control structure and its manufacturing process. Background technique [0002] Carbon nanotubes have a small tip curvature radius, can emit a large number of electrons under the action of an external electric field strength, exhibit excellent field emission characteristics, and are very suitable for use as cold cathode materials for field emission display devices. The working principle of the field emission display is almost the same as that of the cathode ray tube display, so this flat panel display completely inherits the high display image...
