Abstract: A flat panel image sensor is provided by combining the photoconductive imaging electrode of a vidicon with a two dimensional array of cold cathode field emitters commonly used for flat panel Field Emission Display (FED) systems. The FED operates normally to emit electrons which are accelerated in prior art displays towards a luminescent phosphor to generate light output proportional to the cathode emission. Rather than accelerating towards a phosphor, electrons, in accordance with the principles of this invention, are accelerated towards a photoconductor layer to replace charge removed from the layer by an incident radiation pattern directed at the photoconductor layer through a layer of transparant, electrically-conducting material which serves as a radiation window. A large area, low cost, small, flat panel sensor is realized. The transparant, electrically-conducting layer may be partitioned to reduce stray capacitance for large area sensors and the partitioned, electrically-conducting layer permits a parallel readout mode of operation. The sensor includes a means for collimating and focusing the electron beams and may be used with infra red and ultra violet photoconductor materials.

Abstract: An electroluminescent display formed on a ceramic substrate having a front ceramic surface and a back ceramic surface. The ceramic substrate includes a metal core that provides structural support, electrical ground, and heat dissipation. Electroluminescent cells are mounted on the front ceramic surface and driver circuits for driving the of electroluminescent cells are mounted on the back ceramic surface. The driver circuits are positioned directly behind said electroluminescent cells. Connectors extend through said ceramic substrate and the electroluminescent cells to different driver circuits. By positioning the driver circuits close to the EL cells, the drive lines from the drivers to the EL cells are short which allows for high refresh rates and low resistance losses. Each of the driver circuits can drive one electroluminescent cell or a group of electroluminescent cells. EL display cells coupled to a cermet electrode can also be driven by a field emission device or a low power electron beam.

Abstract: Provided is a field emission device. The field emission device includes an insulated cathode substrate facing an anode substrate, a plurality of cathodes arranged on the cathode substrate and separated from each other, and an emitter formed on each of the cathodes. In order to prevent accumulation of charges on an exposed area of the cathode substrate between the cathodes due to electrons discharged from the emitter, the distance between the cathodes is equal to or smaller than a first threshold value, and the distance from the emitter to the end of the cathode is equal to or greater than a second threshold value. Accordingly, in the field emission device in which a plurality of cathodes are separated from each other on the same plane, it is possible to prevent abnormal field emission and arc generation due to accumulated charges between the cathodes, thereby performing stable operation.

Abstract: The present invention provides an enhanced THz electromagnetic source structure achieving a very high aspect ratio of 500 to 1 of electron beam width to electron beam thickness of the electron beam moving in the direction across the grating structure while maintaining its cross-section. The structure comprises a magnetic circuit providing a unique low magnetic field slot placed in a steel core for the placement of an electron gun, thus allowing the electron beam to be focused without the interaction of a magnetic field while still supporting a high magnetic field in the grating region. Additionally, the structure comprises an electrostatic shield preventing potential difference between the anode voltage and the grounded steel core from affecting the focusing of the electron beam.
