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 trapped to form a grid current, which leads to a decrease in the display brightness of the device.
Limited by the gate structure, the effective electron emission area of ​​the carbon nanotube cathode cannot be increased, which also limits the way to further improve the 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...
