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 folded wedge type grid control array 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, raises electron emission efficiency of cathode of Nano carbon tubes so as to be in favor of raising display brightness of whole apparatus. 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 panel field emission display particularly relates to a flat panel display with a folded wedge gate-controlled array structure and its manufacturing process. Background technique [0002] Display technology and monitors occupy a very important position in the development of information technology. The display screens on various instruments provide a lot of information for daily life and work. Carbon nanotubes have unique physical and chemical properties and extremely high mechanical strength, and can emit a large number of electrons without additional energy under the action of an external electric field. Using this operatin...
