摘要： An image sensor array has overlapping responsive zones for detecting incident radiation. The sensor array includes a plurality of collection electrodes for sensing charge and a charge distribution layer in contact with the collection electrodes. The charge distribution layer is configured to distribute charge generated from incident radiation to more than one collection electrode, effectively providing overlapping responsive zones that reduce adverse aliasing effects.

摘要： Pixel elements capable of imaging spatial intensity variations within themselves, and displays comprised of such elements, are described. The pixel elements include a resistance layer disposed between at least one set of electrodes. Over that resistance layer is a liquid crystal material. Over that liquid crystal material is a field electrode. In operation a voltage, whose components are referenced to the field electrode, is applied across the resistance layer. The resulting current flow induces a spatially varying electric field between the field electrode and the resistance layer. That spatially varying electric field results in a corresponding response by the liquid crystal layer which results in a spatially varying light transmission through the liquid crystal material. By varying the voltage across the resistance layer and/or the voltage applied to the field electrode varying amounts of light transmission can be achieved.

摘要： Sensor elements which are capable of sensing illumination edges with subpixel accuracy are described. The sensor elements include a plurality of conductive storage nodes and a plurality of collection electrodes which are in a low resistance, touching relationship with a first semiconductive material layer. A second semiconductive material layer is placed over the first such that the first and second semiconductive material layers and the storage nodes form light sensors. Near the first semiconductive layer is a gate electrode. When a first voltage is applied to the gate electrode the resistance of the first semiconductive material layer between the storage nodes and the conductive collection electrodes is high. Illumination which strikes the sensor element creates electron hole pairs which induce charges on the storage nodes. When a second voltage is applied to the gate electrode the resistance of the first semiconductive material layer between the storage nodes and the conductive collection electrodes becomes low. Charges which have accumulated onto the storage nodes can then easily flow to the conductive collection electrodes.

摘要： Resistance layer structures comprised of a plurality of conductive charge storage nodes, collection electrodes, and an electrically controllable resistance element which connects the storage nodes and the collection electrodes. The resistance of the electrically controllable resistance element can be switched between a low impedance, so as to permit a rapid charge interchange between the various storage nodes and the collection electrodes, and a high impedance, so as to permit an integration of charge onto the storage nodes. Beneficially, the electrically controllable resistance element is implemented as the active region of a metal-insulator-semiconductor device.

摘要： A sensor array has cells, each with a sensing element and a switching element. The sensing element includes a charge collection electrode. An anticoupling layer between the charge collection electrodes and the data lines is structured to reduce capacitive coupling between the electrodes and the data lines below a threshold level at which crosstalk is unacceptable. If charge collection electrodes overlap data lines, the anticoupling layer can reduce capacitive coupling so that crosstalk is no greater than 2%. The anticoupling layer can be a dielectric layer with dielectric constant less than 6 and with thickness greater than 1.5 .mu.m, with the dielectric constant being sufficiently low and the thickness sufficiently great that the anticoupling layer reduces capacitive coupling below the threshold level. Or the anticoupling layer can include a fixed potential sublayer of conductive material, electrically connected to circuitry that holds it at a fixed potential; the fixed potential sublayer therefore reduces capacitive coupling below the threshold level.

摘要： A process of producing a product such as an x-ray sensor array performs two etching operations on an insulating layer to expose different parts of a conductive layer. One etch exposes part of the conductive layer in each unit of cell circuitry in the array without exposing the contact pads at the array's periphery. Then, a conductive layer including ITO is deposited over the insulating layer and patterned to form a conductive element for each unit, with the conductive element contacting the exposed part of the conductive layer. Afterward, a second etch exposes contact pads at the periphery of the array. As a result, the contact pads have high quality surfaces, facilitating testing and wire bonding.

摘要： A product such as an x-ray sensor array includes, for each unit of cell circuitry, a capacitor with upper and lower electrodes. A conductive layer that includes highly conductive metal such as aluminum is patterned to include the upper electrode of the capacitor, the contact leads of a switching element, and the data lines of the array. The upper electrode has an exposed area due to an opening in an insulating layer over it. A conductive element, such as an ITO island, is formed over the insulating layer, contacting the exposed area of the upper electrode so that the conductive element is electrically connected to one of the contact leads of the switching element through the upper electrode. The conductive elements of adjacent units can be separated by the minimum spacing necessary to ensure isolation. Or each unit's conductive element can be offset slightly from the data and scan lines and can also be pulled back from the channel of the switching element, which can be a TFT.
