摘要： A panel display consists of a matrix of picture elements each of which includes with image forming means, e.g. a liquid crystal display element, an electroluminescent display element, a plasma display element or an electrochromic display element, and light sensing means (5) which may be a photoconductor, a photo-diode or a phototransistor. The light sensing means of the picture elements constitute an output signal matrix, by which any picture element illuminated by a light emitting light-pen may be readily identified. If required, information stored in the located picture element may be revised.

摘要： Method of and apparatus for operating an image display system using a hydrid field effect liquid crystal light valve of the type wherein the molecules of the nematic liquid crystal layer are helycally twisted through an acute angle. A polarized projection beam is oriented with its polarisation direction within the acute twist angle and applied to a reflective face of the light valve. A writing light input image is applied to a photoresponsive opposite face in order to modulate the reflected projection beam. An electric field applied across the light is adjusted between two levels to produce either a simultaneous display of multi- color symbology and achromatic (black-white) gray scale images or a separate display of either one of them.

摘要： A device (30) and method for converting an X-ray image into a corresponding output image with light from a different source and a phosphorescent layer (34) in conjunction with a liquid crystal light valve (12, 16, 18, 18, 24, 32). The light valve includes a photosensor layer (32) comprised of a deposited semiconductor material having distinct light and dark photoconductivities, the light photoconductivity being substantially greater than the dark photoconductivity. ' When impinged upon by an particular pattern of X-rays, the phosphorescent layer (32) phosphoresces in a corresponding pattern, which phosphorescence in turn causes the semiconductor layer (32) to be switched to its light photoconductivity in a pattern also corresponding to that of the input X-ray image. The pattern of switched semiconductor in the photosensor layer allows a biasing voltage to be switched over to the liquid crystal layer of the light valve in a corresponding pattern. This voltage pushes the liquid crystal over its electro-optic threshold thereby inducing an output image corresponding to the original input image.

摘要： A solid-state optical device with a plurality of cells having a plurality of optical functions is disclosed. Each of the cells comprises a transparent substrate (11), an anti-reflection film (29) formed on the lower surface of the transparent substrate, a MOS transistor (1) and a capacitor (8) formed on the upper surface of the transparent substrate, a liquid crystal display device (7) formed on the MOS transistor and capacitor, and window (18, 22) for leading a light signal incident on the liquid crystal display device from above to the transparent substrate. At least either a channel region (15) of the MOS transistor and a region (16) intervening between pair electrodes of the capacitor is formed of a photoconductive film. A transparent medium intervenes between the transparent substrate and photoconductive film such that light signal led through the window to the transparent substrate is reflected by an object (30) disposed in contact with anti-reflection film to reach the photoconductive film, thereby generating carriers therein.

摘要： In an electro-optical display device, a fiber optic faceplate (14) which transmits light only through a well-defined solid angle, is optically coupled to an electro-optical display panel (10) having a specularly reflecting surface (26). The display panel can be either an active device, such as laser diodes, or passive such as a dynamic scattering liquid crystal device. The axes of the optical fibers comprising the faceplate (14) are slanted to the display surface (26) at an angle such that the light which enters the front surface of the faceplate and is specularly reflected from the display surface is trapped within the faceplate. However, light emitted or scattered from on-state display elements is transmitted through the faceplate to the viewer. A high contrast display results because off-state display elements on the display surface appear dark under even intense ambient illumination whereas the on-state elements appear bright. The faceplate (14) has two major opposing surfaces which are aligned to one another at a predetermined angle in order to control the size and direction of the display field of view.

摘要： A reflective matrix mirror visible to infrared converter light valve (5) includes a liquid crystal medium (60) for spatially modulating an incident infrared beam by polarization rotation, a photosubstrate (30) for receiving an incident visible wavelength image (115) and for controlling the polarization rotation of the liquid crystal medium (60) responsively to the visible image (115), and a reflective matrix mirror (40). The reflective matrix mirror (40) is positioned between the liquid crystal medium (60) and the photosubstrate (30) and reflects the incident infrared beam (125) back through the liquid crystal medium (60) such that the infrared beam (125) passes through the liquid crystal medium twice and is polarization rotated responsively to the visible wavelength image (115). A polarizer (90) positioned exteriorly of the liquid crystal medium (60) converts the polarization rotation of the infrared beam (125) into output intensity modulation to produce an infrared image (130). The reflective matrix mirror (40) comprises an M x N array of infrared reflective islands comprising metallic or semiconductor/metallic compounds.

摘要： A double Schottky diode light valve (5) includes a liquid crystal (80) for locally modulating a beam (120) by polarization rotation to produce a modulated beam (121), and a photoconductor (40) located adjacent the liquid crystal (80) for receiving and absorbing a second beam (110). The photoconductor (40) controls the polarization responsively to the optical content of the second beam (110). The photoconductor (40) includes a semiconductor substrate and a pair of Schottky diodes (60/40, 30/40) disposed on opposing sides of the substrate. The absorption of the second beam (110) by the substrate (40) produces photogenerated majority carriers. The pair of Schottky diodes (60/40, 30/40) maintains the substrate (40) substantially depleted of such carriers and also reflects the modulated beam back through the liquid crystal.

摘要： The invention provides optical modulation devices and displays of the DHFLC type having a high contrast. Said modulation devices comprise a first substrate and a second substrate which are positioned substantially parallel to each other and which are provided, on their facing surfaces, with, in succession, an electrode layer and an orientation layer. This advantageous effect is achieved by using different orientation layers, the surface energy of the orientation layer of the first substrate being different from the surface energy of the orientation layer of the second substrate, said difference in surface energy being at least 5 mN/m. The orientation layer having the high surface energy is preferably made from rubbed polyimide, and the orientation layer having the low surface energy is preferably made from unrubbed polyorganosilsesquioxane. The optically active layer of the modulation devices in accordance with the invention exhibits a "tilted-bookshelf" structure.
