Large visual displays are comprised of an array of smaller display devices or modules, each of which displays a portion of the image to be displayed so that together the array of smaller display devices displays the complete image. Unlike conventional large displays which necessarily seek to minimize the edge areas of the smaller display elements that do not display an image so as to minimize the âseamsâ or gaps between the image portions, the present display device projects image portions scanned from less than the entire display area of the smaller display devices in an array to create an image on a substantially flat panel that is substantially free of visual âseamsâ or gaps between the image portions. Thus the display device may employ display elements that do not have narrow edges and that are not contiguous to generate overlapping sub-images. Image pixels in what would otherwise be âseamsâ or gaps are generated from the image data and are displayed in proper position and brightness in the displayed image, such as in the overlap regions of overlapping sub-images.

A plural-beam cathode ray tube includes an electron gun directing electrons towards a faceplate having an electrode biased at screen potential. The electron beam is magnetically deflected to scan across the faceplate to impinge upon a pattern of phosphors thereon to produce light of different colors depicting an image. A first conductive coating near the tube neck is biased below screen potential and a second conductive coating between the neck electrode and the faceplate is biased at screen potential. A gap between the first and second conductive coatings varies in distance from the faceplate so as to be non-Z-planar. The non-Z-planar gap is preferably partly within the region wherein electrons are deflected by the magnetic deflection yoke and partly more proximate the faceplate than such deflection region.

A read-only memory (ROM) is disclosed that uses the presence or absence of linear passive electrical elements, such as resistors or capacitors, to encode zeros and ones, permitting a large-area ROM to be fabricated, possibly on a flexible substrate. The ROM includes a substrate, a plurality of row conductors insulated from each other and at least partially layered on a portion of the substrate; a plurality of column conductors insulated from each other and from the row conductors and at least partially layered above or below a portion of the plurality of row conductors, a plurality of amplifiers electrically connected to the column conductors, and at least one linear passive element attached between the row conductors and the column conductors. An amplifier connected to a column conductor has an input impedance much lower than the combined parallel impedance of the linear passive elements connected to that column, thus comprising a virtual ground, and is operable to output a first logical state when one of the linear passive elements is electrically connected between one of the row conductors and one of the column conductors, and operable to output a second local state when said one of the linear passive elements is absent between one of the row conductors and one of the column conductors. The resistive or capacitive arrays can be made into low-cost imagers if the resistors/capacitors are sensitive to electromagnetic radiation or mechanical pressure.

Defect detection apparatus, for optically inspecting a spiral groove of a video disc record, directs a coherent light beam at the grooved surface of the disc. The incident beam, focused at a point beyond the disc surface, illuminates the grooved surface with a light spot that spans a plurality of convolutions of the groove. Relative motion is established between the disc surface and the incident beam in a manner causing the illuminating spot to rapidly scan the groove surfaces in a coarse spiral pattern. The structure of the illuminated groove convolutions, absent any defects, serves as a diffraction grating for diffracting the light into an undeviated zero diffraction order cone of light that converges at a first location in a plane spaced from the disc surface and into deviated higher diffraction order cones of light that converge at additional locations in said plane separated from the first location. A photodetector is positioned to be in registry with the first location and spaced from said additional locations. A blocking means is placed over a central region of the photodetector to normally intercept the zero diffraction order light, thereby preventing the conversion of light energy to electric energy by the photodetector when defect-free groove regions are illuminated.

A method of producing an information storage disc by optical techniques includes the steps of coating a flat, reflective disc surface with a thin coating of radiant energy sensitive material, moving the coated disc relative to a coherent light beam, which is intensity modulated with the information to be recorded, to expose the radiant energy sensitive material, and developing the radiant energy sensitive material to form a track having geometric variations in the disc representative of the modulated information signals.

A method of aligning the mirrors and bore tube axis of a laser without actually operating the laser comprising the directing of two light beams through the bore tube collinear with the bore tube axis; the two light beams being directed through the tube from opposite ends of the tube. The mirrors are positioned so that one or both of the light beams are reflected from the mirrors along paths also collinear with the bore axis. A fine alignment of the mirrors is provided by detecting the light of a modulated laser beam passed through the bore and mirrors. The mirrors are accurately positioned when the detected modulated laser beam provides a peak output.

Two ring mounts extend around and are secured to a gas laser discharge tube. The ring mounts are positioned near opposite ends of the laser tube. The laser discharge tube is in a prealigned relationship to the external perimeter of each ring mount. The mounts serve as the means for mounting the laser discharge tube. The mounts are formed by placing the laser discharge tube within two molds and aligning the laser output beam with respect to the molds. Plastic material is then forced into the molds and allowed to harden so as to permanently fix the aligned relationship of the tube with respect to the mold.

an optical playback system is provided for a record having an information track comprising a succession of depressed areas alternating along the length of the information track with relatively non-depressed areas. Light is diffracted by the track to form a zero diffraction order cone of light, and a pair of differently deviated first diffraction order cones of light, each of the latter having a respective region of overlap with the zero diffraction order cone. A light detector, having four independent photosensitive elements disposed symmetrically about the center of a light accepting region of a common housing, is disposed in the path of the diffracted light so that the light accepting region intercepts the zero diffraction order cone. Two photosensitive elements detect two separate regions of overlap representing the recorded data. The remaining elements provide radial tracking signals.
