ABSTRACT:
This disclosure depicts a high-voltage cathodoluminescent gas discharge image display panel having an ordered array of display elements. The panel includes envelope means containing an ionizable gas at a predetermined very low pressure. The envelope means includes a transparent faceplate on the inner surface of which are disposed cathodoluminescent target elements. Electron source means produces at a given time at least one high-density electron beam, and includes means to cause a plasma sac to generate and gather electrons, and accelerate them to form a concentrated electron beam. An ultor electrode receiving a predetermined relatively high ultor voltage establishes a high voltage gradient in a plasma-free acceleration section which is effective to straight-line accelerate said electron beam in a substantially collision-free path directly into high-energy bombardment of the cathodoluminescent target elements. The panel includes light-stopping means whereby the useful visible light is solely that produced by high-energy electron bombardment of the target elements. Other structures including means for electron beam modulation are disclosed.
