Abstract: Improved image storage and display devices of the type which includes a layer of phosphor material which is stimulated to emit light through photoluminescence. The intensity of emitted light is varied by applying an electric field to the phosphor layer. The field may be applied to the phosphor layer by sandwiching the layer between a layer of insulating material and a layer of electrically conductive material and subjecting the insulator to an electron beam. To alter the field strength at selected locations a writing electron beam is focussed on the insulator at these selected locations. In the alternative, the phosphor layer may be covered on one surface with insulation materials forming a charge trap and the phosphor and insulation layers sandwiched between sets of orthognal electrically conductive strips. Selective field alteration is accomplished by X-Y addressing an orthognal pair of conductive strips.

Abstract: A ferroelectric ceramic is mounted within a CRT in a "strain-biased" state, so that it is birefringent. A reflective layer is mounted adjacent the ceramic, and a photoconductive layer is mounted adjacent the reflective layer. With a potential applied across the ceramic-photoconductive layer combination, an image written upon regions of a phosphor target adjacent the photoconductive layer by an electron beam, results in the flow of local charge through corresponding regions of the ceramic, thereby changing the polarization thereat. The flow of polarization charge acts to modulate the birefringence in the ceramic, in accordance with the pattern of the image. A corresponding pattern of brightness is then projected upon an external screen. A "scattering mode" arrangement is also employed.

Abstract: A display device having an inert gas-filled, transparent envelope, containing a set of parallel cathode elements an anode grid structure forming a venetian blind type structure and a glass support plate carrying a set of parallel conducting strips perpendicular to the plane of the parallel cathode strips and coated with a layer of ZnO phosphor. Light is emitted by the phosphor when one of the cathode elements is connected to a negative potential, the anode grid structure connected to a ground potential and one of the phosphor bearing conducting strips is connected to a low positive signal voltage. Color displays may be generated by applying a series of phosphors which generate different colors in an alternating fashion on the glass support plate.
