A newly designed plasma display with a cylindrical hollow cathode has been proposed and investigated to study the relationship between the photoluminous efficiency and the discharge characteristics. The photoluminous efficiency and discharge characteristics are dependent on the geometry factors of the cylindrical hollow cathode and gas pressure in the plasma display. When p/spl times/d (where p is the gas pressure and d is the hole diameter of the cylindrical hollow cathode) is below 2 torr/spl middot/cm, the plasma display has as much as five times higher luminous efficiency compared to that for p/spl times/d above 2 torr/spl middot/cm and it also shows a positive current-voltage (I-V) slope as in an abnormal glow.
