More Information
Summary:The display endures an electric shock of ion collision effect at electron emission, prolongs a lifetime of circular negative electrode, and improves a productivity by simplification manufacturing procedure. The display includes an upper glass which contains anode electrode, a lower glass (2) which contains cathode electrode, a conduction layer (5) which is laminated on the upper of lower glass (2), a circular negative electrode (60) which is located against a fluorescenf (4) of upper glass (2), a concave groove (61) which is formed on the upper of circular negative electrode (60), and a peak unit (62) which radiates electron.
