    Abstract: A light emitting diode display package and method of fabricating a light emitting diode (LED) display package including a LED array display chip, fabricated of an array of LEDs, formed on a substrate, having connection pads positioned about the perimeter of the LED array display chip, a separate silicon driver chip having connection pads routed to an uppermost surface, positioned to cooperatively engage those of the display chip when properly registered and interconnected using wafer level processing technology. The display chip being flip chip mounted to the driver chip and having a layer of interchip bonding dielectric positioned between the space defined by the display chip and the driver chip. The LED display and driver chip package subsequently having selectively removed the substrate onto which the LED array was initially formed, thereby exposing the connection pads of the display chip and a remaining indium-gallium-aluminum-phosphide (InGaAlP) epilayer. The light emitted from the LED display chip, being emitted through the remaining indium-gallium-aluminum-phosphide (InGaAlP) epilayer of the display chip.

    Abstract: A ballistic charge transport device including an edge electron emitter defining an elongated central opening therethrough with a receiving terminal (e.g. an anode) at one end of the opening and a getter at the other end. A suitable potential is applied between the emitter and the receiving terminal to attract emitted electrons to the receiving terminal and a different suitable potential is applied between the emitter and the getter so that contaminants, such as ions and other undesirable particles, are accelerated toward and absorbed by the getter.

    Abstract: A configurable display comprising a distributed Bragg reflector having a plurality of flexible, compressible polymer layers is provided. The polymer layers are transparent and comprise alternating layers of differential index of refraction material so that a reflective surface is formed at each interface between the alternating layers. The polymer layers are sandwiched between a first electrode which is transparent and a second electrode. Thickness of each of the layers is designed such that light reflecting from the reflective surfaces interferes constructively at predetermined wavelengths. The thickness of each of the layers is altered by application of a static potential between the first and second electrodes which deforms the polymer layers thereby shifting the wavelength at which constructive interference occurs. In this manner wavelength and amplitude of reflective light can be modulated by a voltage applied between the first and second electrodes.
