Abstract:
A display device comprising a panel structure including a plurality of gas-filled cells and including, within the body of the panel, gas communication channels extending between selected cells to provide a selective flow of excited gaseous particles from certain cells to others to prime the receiving cells and thereby control the transfer of glow between the cells.
Abstract:
A system is disclosed for the examination and inspection of integrated devices such as integrated circuits using 3-D laminography. X-rays are transmitted through the integrated device, and are incident on a photoemissive structure that absorbs x-rays and emits electrons. The electrons emitted by the photoemissive structure are shaped by an electron optical system to form a magnified image of the emitted electrons on a detector. This magnified image is then recorded and processed. In some embodiments, the incidence angle of the x-rays is varied to gather multiple images that allow internal three-dimensional structures of the integrated device to be determined using computed laminography. In some embodiments, the recorded images are compared with reference data to enable inspection for manufacturing quality control.

A display substrate, an organic light emitting diode display device having the same, and a manufacturing method thereof are disclosed. The display substrate includes a first pixel separating portion and a second pixel separating portion extending from the pixel separating portion and disposed around a pixel portion. Therefore, the number of processes for forming the organic light emitting diode display device can be reduced, and corrosion of a first electrode of the organic light emitting diode display device can be prevented.
Abstract:
A photocathode arrangement comprises a body of semiconductor material, such as gallium arsenide which is bonded to a fiber optic face plate. A thin anti-reflection coating of silicon nitride is positioned between the body and the plate and forms an integral part of the bond. The properties of the glasses from which the fiber optic face plate is made are carefully chosen to minimize crystal dislocations which can be introduced into the body of gallium arsenide when it is bonded to the face plate. Such crystal dislocations can seriously impair the performance of the photocathode. It has been found that it is advantageous to use a glass having an annealing temperature of about 575.degree. C. or less. Because of high temperature processing steps, its softening temperature must be about 680.degree. C. or greater. The photocathode arrangement so formed is intended to constitute the input port of an image intensifier.
Abstract:
A discharge luminescence element array comprising a pair of parallel insulating plates and a separator entirely sealed between the pair of insulating plates in which a groove-like gas flow path is provided between one of the plates and the separator for evacuating and providing gas from and to discharge spaces defined by the separator and the pair of insulating plates.
Abstract:
A storage target for a read, write and erase memory is disclosed utilizing a semiconductor memory storage element. The storage of information relies on charge storage to create or pinch off a conductive channel between an internal conductive electrode and isolated diode junctions. An electron beam, irradiating each storage area, is used for reading, writing and erasing.
Abstract:
An amorphous semiconductor layer is employed in the display panel disclosed herein. An electroluminescent layer is sandwiched between the amorphous semiconductor layer and a set of parallel spaced conductors. An AC signal is applied to the conductors so that adjacent conductors are 180* out of phase. A field is established between adjacent conductors which passes up through the electroluminescent layer across the layer of amorphous semiconductor material and back down through another portion of the electroluminescent layer. If the amorphous semiconductor material is in a low resistance state the field across the electroluminescent material is made sufficiently strong to cause it to emit light. By switching the amorphous semiconductor material at selected regions, the electroluminescent material emits light in accordance with a desired pattern of information to be displayed. Systems are disclosed for switching the amorphous material in a variety of ways, and techniques for varying the intensity and contrast of the display are also disclosed.
