摘要： This invention is directed to a semiconductor structure that includes at least one wafer that is fully depleted of all mobile carriers and is used as a medium for the movement of spatially modulated signal represented by charge carriers through the wafer with a spatial resolution that is smaller than the thickness of the wafer. This may be used in the form of a continuous high resolution silicon photodiode substrate to serve as an image input means for an electro-optical display medium, such as a liquid crystal. Next to the photoactivated substrate is a liquid crystal and next to the crystal is a transparent electrode. The photodiode is reverse biased and both of its sides are depleted of all mobile charges throughout its entire thickness. Thus, charges generated in the substrate move to the display not by diffusion as in prior art devices (e.g. the solid state silicon vidicon) but by the influence of the electric field which tends to minimize their lateral spread and thereby achieves a high spatial resolution in spite of the continuous character of this silicon diode device.

摘要： There is disclosed an anisotropically conductive interface comprising a plurality of cermet and dielectric layers for use in electro-optical devices to separate a substrate driver from an electro-optical display medium to prevent display light from affecting the driver. The substrate may be a photosensor, a charge coupled device or other matrix addressing circuitry arrangement. In general the substrate is one which can provide spatially modulated voltage and/or current patterns. The display medium may be a liquid crystal, an electro-chromic, an electro-luminescent material or the like. The interface provides direct current conductivity through the interface, insulative maintenance of the spatial modulation of the signal across the interface, light reflectivity, and high attenuation of transmitted light.

摘要： There is disclosed a silver doped silicon single crystal charge storage photodiode substrate suitable for use in an alternating current driven liquid crystal light valve. The gain capability of the charge storage photodiode makes it possible to construct a single crystal substrate ac light valve very similar in structure to that presently being used with a cadmium sulphide photodiode, but having improved operating characteristics and benefitting from a more fully developed manufacturing technology for silicon devices. One specific embodiment of such a single crystal substrate is a silicon substrate doped with a slow recombination center element such as silver.

摘要： An electron beam addressed crystal light valve (LCLV) produces an AC voltage across a liquid crystal layer from a single polarity electron beam, and exhibits very high resolution. A mirror and a thin layer of partially conductive material are deposited on a support membrane on the electron beam side of the liquid crystal. The partially conductive layer is divided into a series of pixel elements by a conductive matrix which faces the electron beam. Electrons from the beam are absorbed by the partially conductive layer to establish a negative voltage across the liquid crystal, and then flow out to the conductive matrix to produce an AC voltage prior to the next electron beam scan. The conductive matrix is connected in circuit with a transparent electrode which provides a voltage reference on the readout side of the liquid crystal. The elements of the device are designed with electrical parameters that produce a discharge rate from the partially conductive layer fast enough to complete an AC cycle between successive electron beam scans, but slow enough for the liquid crystal to respond and produce an image.

摘要： There is disclosed a reflective type liquid crystal light valve means for converting a visible wavelength dynamic image to an infrared wavelength dynamic image. The device employs an infrared reflecting and visible transmitting indium-tin-oxide film which is external to the liquid crystal layer and active films and which also serves as a conductive electrode for the device. In operation, a visible image is transmitted through a visible transmitting faceplate and through this ITO film to a photosensor to modify its impedance. An infrared projection beam is transmitted through a second infrared transmissive faceplate, through the liquid crystal means and the photosensor to the IR reflective dichroic film and thence back through the rest of the liquid crystal cell for projection.

摘要： Method of and apparatus for operating an image display system using a hybrid field effect liquid crystal light valve of the type wherein the molecules of the nematic liquid crystal layer are helically twisted through an acute angle. A polarized projection beam is oriented with its polarization 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 valve is adjusted between two levels to produce either a simultaneous display of multicolor symbology and achromatic (black-white) gray scale images or a separate display of either one of them.

摘要： Method of and apparatus for operating an electro-optical system for producing high quality images from a liquid crystal light valve.A polarized projection beam is directed to the reflective surface of a liquid crystal light valve for polarization modulation by means of an input image. The beam is polarization analyzed to thereby generate an output image which typically suffers from color and brightness defects caused by economically unavoidable tolerance variations in the electro-optical system. A second beam of light is generated having a light of a selected color different from the projection beam, is spatially varied in intensity by a spatially graded filter, and super-imposed on the output image so as to eliminate the color and brightness defects as well as enhance color contrast and brightness of the image. The color of the second beam is selected so as to mask background color variations and improve color contrast on the output image while the graded intensity filter is selected to additively compensate for background brightness variation of the output image.

摘要： In a light actuated device such as an alternating current driven light valve or other display device requiring the photocapacitance of a light responsive layer in a photodiode to be modulated in response to changes in incident or writing light, sensitivity is an important factor, especially when a cathode ray tube phosphor image is the source of such light. This sensitivity can be improved by more than an order of magnitude by using a graded defect center (as defined hereinbelow) concentration, graded band gap layer in said diode which can produce a graded optical absorption coefficient between two regions of the layer so that most of the incident light is absorbed in the region near the semiconductor rectifying junction of the diode to store charge near this junction by this or any similar action. In one particular embodiment disclosed a cadmium sulfide photoconductor is used and the defect center density and hence the optical absorption coefficient for the incident light beam in the light sensitive region is graded from a low value on the light input side to a higher value near the junction forming interface with a cadmium telluride light blocking layer by varying the defect concentration in the cadmium sulfide during the film preparation by progressively lowering the temperature during sputter deposition. In a second embodiment this grading is accomplished by alloying cadmium sulfide with cadmium selenide near the cadmium telluride region thus introducing defect centers and lowering the absorption band edge. In both embodiments charge carriers are generated which are stored in the region adjacent to the junction interface and thereby change the photocapacitive depletion width adjacent to the junction to enhance the sensitivity of the diode.
