    Abstract: A light-emitting diode (LED) structure includes an LED substrate having a first side and a second side opposing the first side. One or more light-emitting diodes are disposed on the first side and arranged to emit light through the LED substrate. In certain embodiments, a wire-grid polarizer is disposed on the second side and arranged to polarize light emitted from the one or more light-emitting diodes. A plurality of different colored LEDs or an LED with one or more color-conversion materials can be provided on the LED substrate to provide white light. A spatially distributed plurality of the LED structures can be provided in a backlight for a liquid crystal display. A polarization-preserving transmissive diffuser can diffuse light emitted from the LED toward the liquid crystal layer and a polarization-preserving reflective diffuser can diffuse light emitted from the LED away from the liquid crystal layer.

    Abstract: The disclosed technology relates generally to methods and systems for controlling the release of micro devices. Prior to transferring micro devices to a destination substrate, a native substrate is formed with micro devices thereon. The micro devices can be distributed over the native substrate and spatially separated from each other by an anchor structure. The anchors are physically connected/secured to the native substrate. Tethers physically secure each micro device to one or more anchors, thereby suspending the micro device above the native substrate. In certain embodiments, single tether designs are used to control the relaxation of built-in stress in releasable structures on a substrate, such as Si (1 1 1). Single tether designs offer, among other things, the added benefit of easier break upon retrieval from native substrate in micro assembly processes. In certain embodiments, narrow tether designs are used to avoid pinning of the undercut etch front.

    Abstract: An inorganic light-emitting diode structure includes a transparent substrate and an inorganic semiconductor having a conduction layer and a light-emitting layer over and in contact with only a portion of the conduction layer. A first metal contact is in electrical contact with the conduction layer and a second metal contact is in electrical contact with a second contact portion of the light-emitting layer so that a current supplied between the first metal contact and the second metal contact through the inorganic semiconductor causes the light-emitting layer to emit light. A dielectric layer is located over at least a portion of the light-emitting layer and a reflective layer is located over at least a portion of the dielectric layer. The reflective layer encapsulates the light-emitting layer exclusive of the portion of the conduction layer in contact with the light-emitting layer.

    Abstract: A small-aperture-ratio display includes a display substrate and a plurality of spatially separated pixel elements distributed over the display substrate. Each pixel element includes one or more light emitters. An active electrical component is electrically connected to each of the pixel elements and each active electrical component is located on the display substrate at least partly between the pixel elements. The display substrate has a contiguous display substrate area that includes the pixel elements, the light emitters each have a light-emissive area, and the substrate area is greater than or equal to one-quarter the combined light-emissive areas of the light emitters.

    Abstract: The disclosed technology relates generally hybrid displays with pixels that include both inorganic light emitting diodes (ILEDs) and organic light emitting diodes (OLEDs). The disclosed technology provides a hybrid display that uses a mixture of ILEDs and OLEDs in each pixel. In certain embodiments, each pixel in the hybrid display includes a red ILED, a blue ILED, and a green OLED. In this instance, the OLED process would not require a high resolution shadow mask, thereby enhancing the manufacturability of OLEDs for larger format displays. Additionally, the OLED process in this example would not require any fine lithography. The OLED subpixel (e.g., green subpixel) can be larger and the ILEDs can be small (e.g., micro-red and micro-blue ILEDs). The use of small ILEDs allows for other functions to be added to the pixel, such as micro sensors and micro integrated circuits.
