Abstract

This invention relates to a panel display with an accurate location trap cathode array structure and its process method, in which, said display includes a sealed vacuum cavity composed of a cathode panel, an anode panel and surrounding glasses, a photoetched anode conduction layer on the anode panel and a fluorescence powder layer on the anode conduction layer, a supporting wall structure and getters, an accurate location trap cathode array structure prepared on the cathode panel capable of determining the growing position of the carbon nm tube cathode and controlling its location, length and number and integrating with the control grating to reduce distances between them and avoid short circuit.

Description

technical field [0001] The invention belongs to the fields of plane display technology, microelectronic science and technology, vacuum science and technology, and nano science and technology, and relates to the manufacture of flat panel field emission displays, in particular to flat panels for carbon nanotube cathodes. The device manufacturing aspect of the field emission display particularly relates to the manufacturing process of the field emission flat display device of the carbon nanotube cathode with a precisely positioned well cathode array structure. Background technique [0002] In recent years, flat panel displays have been widely recognized for their advantages of high definition, flat panel, high image quality, light weight, and thin profile, and their application range has become wider and wider. The field emission flat panel display device made of carbon nanotubes as the cathode material is an emerging planar device. In addition to the common characteristics of ...
