A gas discharge display panel incorporating phosphor protected by undercoats and overcoats. The device is comprised of a pair of substrates, each of which has an electrode array thereon with the dielectric coating on at least one of the electrode arrays. An array of channels having sidewalls is formed in the dielectric layer with an array of channels corresponding to and aligned with one of the electrode arrays. The channels have sidewalls and lands between channels with a protective undercoat on the channel sidewalls and a photoluminescent phosphor on the protective undercoat. Due to the sloping nature of the sidewalls and the photoluminescent phosphors being sandwiched between the protective undercoat and overcoat and the channel walls in which the phosphor is placed outside the path of charged particles produced on discharge but close or near the site of the UV production, the arrangement significantly enhances the light output because the phosphor surfaces are greater in extent area wise and are closer to the UV sources in the discharge and are not in the path of the discharge products. Since the light is produced in two spaced areas of phosphor by the UV produced on discharge, more light is produced and electrodes have less attenuating effect on visible light emission from each side.

Gas discharge (plasma) displays

A gas discharge device containing at least two electrodes is shown, at least one thereof being insulated from the gas by a dielectric member containing a predetermined beneficial amount of a source of at least one Lanthanide Series rare earth including CeO.sub.2 or La.sub.2 O.sub.3. In one embodiment, a multiple gaseous discharge display/memory panel has an electrical memory and is capable of producing a visual display, the panel having an ionizable gaseous medium in a gas chamber formed by a pair of opposed dielectric charge storage members, each of which is backed by an array of electrodes that are oriented with respect to the array behind the opposing member to define a plurality of discrete discharge volumes constituting a discharge unit.

Gas discharge display device containing source of lanthanum series

A gas discharge device containing at least two electrodes is shown, at least one of the electrodes being insulated from the gas by at least one dielectric insulating member containing a predetermined beneficial amount of an oxide of at least one lanthanide series rare earth metal or at least one actinide series rare earth metal. In one embodiment, a multiple gaseous discharge display/memory panel having an electrical memory and capable of producing a visual display is used, the panel having an ionizable gaseous medium in a gas chamber, formed by a pair of opposed dielectric material charge storage members, each of which is respectively backed by an array of electrodes, the electrodes behind each dielectric member being oriented with respect to the electrodes behind the opposing member so as to define a plurality of discrete discharge volumes constituting a discharge unit. Each opposing dielectric surface is coated with a metal oxide of the lanthanide rare earth series or the actinide rare earth series.
