Abstract: A backframe may be utilized to align a plurality of emissive display tiles precisely with respect to one another. The individual display tiles may be removable from the backframe for replacement or other reasons. As a result, the spacing between individual tiles in an overall large format display may be precisely controlled in some cases. In addition, regularly occurring gaps between adjacent tiles may be filled with a suitable light absorbing material to reduce the visibility of seams.

Abstract: A night viewer (10) is adaptable to generate an enhanced image suitable for viewing through an optical scope (16). An input end (18) of the viewer (10) receives the image to be enhanced through an objective lens (20). An image enhancing unit (22) enhances the image. The enhanced image is optically transmitted from a display (28) to the ocular lens (24) of the scope (16). The display (28) is operably connected with the image enhancing unit (22) to display the enhanced image. A Risley prism (30) located in an image path (32) is used to controllably adjust and to maintain boresight alignment (36).

Abstract: A light directing apparatus comprising an LED array having RGB light emitting diode structures arrayed longitudinally along a substrate to form a plurality of RGB triplet groups and a lenslet array having a plurality of lenslet structures positioned adjacent a respective one of the RGB triplet groups. The lenslet structures include for each respective RGB triplet group a plurality of cylindrical lenses indexed to its respective RGB triplet group. The cylindrical lenses are longitudinally arrayed in parallel to said RGB light emitting diode structures. This arrangement results in greater optical efficiency because light from the LEDs is preferentially directed in a desired direction where an observer is most likely to be.

Abstract: An imaging device may include two channels, for example each with different magnification or fields of view as two examples. The user may select one of the channels and the image captured through that channel may be both viewed through a viewfinder and recorded on an imaging array or other recording media.

Abstract: An organic light emitting device display may be formed with a first layer having standard thicknesses. The first layer may be manufactured to include the organic light emitting device material. The first layer may be secured to a second layer to form a panel. Thereafter, the resulting panel can be subjected to a grinding operation to reduce the thickness of the first layer.

Abstract: A flat panel display may be formed with transverse row and column electrodes. Contacts may be made through one electrode to another electrode by forming an offset in the first electrode to reach the second electrode. As a result, the fill factor of the resulting display may be improved.

Abstract: A fiber optic connector system may include a elliptical reflector arranged to couple light from one optical fiber to another. The elliptical reflector has two foci, one of which may correspond to an end of a first optical fiber and the other of which may correspond to an end of another optical fiber. Thus, light emitted from one fiber may be coupled to another fiber.

Abstract: An emissive display may include a faceplate that improves contrast and increases light efficiency in some embodiments. The emissive display may be covered by a plurality of cones that define light pipes between the cones. The cones may be reflective on one surface to reflect outwardly through a microlens. The inside surfaces of the cones may be light absorbing to absorb stray light that would not otherwise be properly emitted from the display.

Abstract: An integrated night vision device and laser range finder provides both night-time and day-time imaging by use of an image intensifier tube, as well as providing laser range finding operations both day and night. In a laser range finder mode of operation the device projects a pulse of laser light into a scene being viewed, and a power supply and laser range finder circuit of the device temporarily utilizes the image intensifier tube as a sensor to detect reflected laser light. During laser range finding, imaging is cut off for a very short time interval. Also, during imaging operations, the power supply and laser range finder circuit operates the image intensifier tube in a unique way in order to provide both improved automatic brightness control (ABC) and improved bright-source protection (BSP). The ABC and BSP functions are coordinated with the laser range finding function in order to prevent interference by the ABC or BSP functions with laser range finding operations.
