Plasma column
A plasma discharge display device comprises a generally columnar chamber with a pair of electrodes tangentially located at opposite ends of the chamber for ionizing gas in the chamber. The columnar chamber comprises a cylindrical portion interconnected with a generally spherical portion. The configuration of the chamber generates an active (but not hyperactive) plasma discharge that is continuous, has a full motion and with minimal noise without the need of additional adulterants for instability.
