Abstract: A field-effect storage cathode ray tube with layer of electroluminescent phosphor external to the tube to allow removal and replacement thereof. The inner surface of the tube faceplace is contacted with a conductive mesh. A layer of semicondutor then contacts the exposed inner surface of the faceplate in the mesh openings and a layer of insulator contacts the layer of semiconductor. An array of conductive pins extends through the faceplate from the layer of phosphor in contact with its outer surface to the semiconductor within the respective mesh openings. A charge pattern written on the layer of insulator acts to vary local conductivity in the semiconductor and thus vary alternating current flow through local pins to cause a pattern of light emission from the phosphor corresponding to the charge pattern.

Abstract: Modification of a display storage cathode ray tube that employs an electron beam for impingement on an insulating phosphor to switch the latter from an OFF state (low voltage) to its ON state (high voltage), using a flood beam of electrons to maintain the phosphor stably either at high or low voltage. Modification consists in using a light pen, having a higher intensity or different spectral distribution than the ambient light of the cathode ray tube, which is used to shift the voltage of the phosphor by photoconductive action toward the potential of a backplate to achieve either writing or erasing, depending on the backplate potential.

Abstract: An electro-optical signal storing device is disclosed and more particularly, an improved ''''dark-trace'''' cathode ray storage tube. A cathode ray tube structure is provided having a cathodochromic viewing screen with a thin phosphor layer on its back surface. An electron gun produces an electron beam which is modulated by an input signal. Voltage is applied to the accelerating anode of the tube to allow the beam to penetrate the phosphor layer and darken the cathodochromic screen in the regions determined by the input signal and therefore produces a pattern on the screen. During the initial writing mode, the screen is scanned with a relatively low beam current and a high writing speed, thereby producing a dark-trace pattern having minimal contrast. After the dark trace pattern is written, the input signal is cut off and the anode voltage is reduced. By scanning the screen in raster fashion, the electron beam generates a flying light spot on the phosphor layer which is partially penetrated, causing limited darkening of the cathodochromic screen. During the scanning operation, the light from the phosphor screen which passes through the cathodochromic screen is reflected from a partially transmissive mirror and is sensed by a photocell capable of intercepting light over a wide angle. The output of the photocell is amplified and fed back to the control grid of the cathode ray tube. When the photocell senses a decrease in light, the beam current is increased so that when the beam scans a darkened area, the reduced light produces an increased beam current through the feedback loop such that, during scanning, the previously darkened areas will be further darkened relative to undarkened areas resulting in a high contrast image.

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.

Abstract: A ferroelectric ceramic is mounted within a CRT in a ''''strainbiased'''' 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 field-effect storage cathode ray tube is provided with a gasdischarge panel arrangement for display output. A transparent conductive mesh is mounted within the panel adjacent the transparent front plate thereof, and an array of conductive pins extend through the panel backplate from within the panel to the other surface of the backplate. A conductive mesh pattern is formed upon the outer surface of the panel backplate in a manner so that each of the respective mesh openings surround a respective pin. A layer of semiconductor material is deposited over the mesh and the backplate exposed by the mesh openings, and a layer of insulation is deposited upon the layer of semiconductor. A charge pattern written on the layer of insulation acts to increase local conductivity in the semiconductor, causing increased current flow between local pins and adjacent mesh. Current flow through the pins determines a pattern of light emission corresponding to the charge pattern.
