Problems solved by technology

However, the high working voltage of the gate is a problem that is still difficult to solve
Since the electron beam of the carbon nanotube cathode can only reach the anode after passing through the grid structure, affected by the positive voltage of the grid, some electrons are

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 bevel shape low grid structure, which is capable of increasing the electron ejecting efficiency of the nanotube and increasing the 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 an inclined plane bottom gate emission structure and its manufacturing process. Background technique [0002] The radius of curvature of the top of the carbon nanotube is relatively small, and the working time of emitting electrons is long. It is a cold cathode emission material with excellent performance. The field emission flat panel display developed by using carbon nanotubes as the cathode is a new type of flat display device, which has the characteristics of high brightness, high definition, and high display resolution, and has already attrac...
