Abstract: A multipersistence display device is described which comprises a cathode-ray tube whose faceplate is coated with a layer of an ultraviolet-emitting phosphor. Provided on the ultraviolet phosphor layer is a layer of a phosphor-emitting visible light. The electron beam accelerating voltage of the cathode-ray tube is selectively controlled; a lower voltage causing the electron beam to excite the visible phosphor layer, and higher voltage causing the electron beam to excite the ultraviolet phosphor layer. An image-storage panel is included for storing the ultraviolet image which is produced when the ultraviolet phosphor layer is excited. An optical image system is provided for projecting images appearing on the screen of the cathode-ray tube onto the imagestorage panel. Thus, when the cathode-ray tube is operated at the lower voltage to excite the visible phosphor, dynamic information can be displayed on the image-storage panel and, when the cathode-ray tube is operated at the higher voltage to excite the ultraviolet phosphor, static information can be stored in the image-storage panel and displayed by the action of an electroluminescent material thereby.

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: Photocopying and magnetic recording re enhanced by employing a recording medium, such as a heat-sensitive paper or a magnetic film adjacent to a semiconductor layer. When the semiconductor is exposed to a low level light image, a charge pattern is created in its surface which is retained and which produces a conductivity pattern in the semiconductor layer. The application of radio-frequency power to the semiconductor converts the conductivity pattern to a heat pattern which is recorded as a visible image on the heat-sensitive paper or as data on the magnetic film.

Abstract: Surface acoustic waves are propagated along piezoelectric material, in response to an electrical signal applied to an input transducer. During propagation along the material, the propagation surface of the piezoelectric material is flooded with a short burst of electrons, causing the emission of low energy secondary electrons. These electrons are immediately attracted from the negative to the more positive adjacent regions of the surface, neutralizing any potential variations on the surface. After the acoustic waves thereon have subsided, electrons trapped on the surface are left behind in a frozen pattern corresponding to the pattern of the acoustic waves. The acoustic waves can be reformed by again flooding the surface with a short burst of electrons. Output transducer means act to transform the reformed waves into an electrical signal.
