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.

This disclosure sets forth means and method for scanning a high voltage cathodoluminescent television, alpha-numeric or other image display panel having a row and column array of individually controllable plasma-sac-type gas-discharge display elements. The panel envelope contains an ionizable gas at very low pressure, and includes a transparent faceplate on the inner surface of which are disposed cathodoluminescent target elements associated with the display elements. A plasma-sac-generating means includes cathode means and anode means for forming a gas discharge plasma or plasmas, and means for constricting the plasma or plasmas to simultaneously form one or more electron-beam-generating plasma sacs. Control means are provided for controlling the plasma-sac-generating means such that at a given time a plurality of electron beams are generated, each associated with a predetermined display element and target element. Included are means for accelerating the beams from the plasma sac or sacs into high-energy impingement on respectively associated target elements.

A flat panel display arrangement is disclosed in which a plurality of plasma sacs are simultaneously generated from cathodes in sections disposed in side-by-side relation, supporting walls being provided between adjacent sections. Row and column electrodes are provided in orthogonal relation for effecting simultaneous scanning of all sections, using a zig-zag scanning arrangement.
