Problems solved by technology

At present, in most display devices, the structure mode in which the gate is located above the carbon nanotube cathode is adopted. The manufacturing process is relatively simple, and the control function of the gate is very significant, but the formed gate current is also relatively large. It is unfavorable for further improving the brightness of the overall display device

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 flat panel field emission display, especially relates to a flat panel display with multi-cathode side gate 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, and form a unique field emission phenomenon, which is very suitable as a cathode material for field emission flat panel displays. The field emission flat-panel display device based on the principle of field electron emission is a new type of flat-panel display technology with great market potential and development an...
