Present invention relates to flat-panel display having integrated fork shape field emitting cathode array architecture and making technology. It contains anode panel and concave cycle glass enclose constructed sealed vacuum cavity, anode panel having photo etched anode conducting layer and phosphor powder layer anode conducting layer, growing carbon nanotube cathode, knee wall structure and getter element, cathode panel having integrated fork shape field emitting cathode array architecture, shortening distance between signal grid and cathode and reducing whole device operating voltage, at the same time highly integrating control grid and carbon nanotube cathode, said grid having strong control action to carbon nanotube cathode electron emission. Said invention raises carbon nanotube cathode electron emission efficiency having reliable manufacturing process, simple technology, low cost, and simple structure etc advantages. |
