Abstract: The disclosed technology provides micro-assembled micro-LED displays and lighting elements using arrays of micro-LEDs that are too small (e.g., micro-LEDs with a width or diameter of 10 μm to 50 μm), numerous, or fragile to assemble by conventional means. The disclosed technology provides for micro-LED displays and lighting elements assembled using micro-transfer printing technology. The micro-LEDs can be prepared on a native substrate and printed to a display substrate (e.g., plastic, metal, glass, or other materials), thereby obviating the manufacture of the micro-LEDs on the display substrate. In certain embodiments, the display substrate is transparent and/or flexible.

Abstract: In certain embodiments, a method of making a semiconductor structure suitable for transfer printing (e.g., micro-transfer printing) includes providing a support substrate and disposing and processing one or more semiconductor layers on the support substrate to make a completed semiconductor device. A patterned release layer and, optionally, a capping layer are disposed on or over the completed semiconductor device and the patterned release layer or capping layer, if present, are bonded to a handle substrate with a bonding layer. The support substrate is removed to expose the completed semiconductor device and, in some embodiments, a portion of the patterned release layer. In some embodiments, an entry path is formed to expose a portion of the patterned release layer. In some embodiments, the release layer is etched and the completed semiconductor devices transfer printed (e.g., micro-transfer printed) from the handle substrate to a destination substrate.

Abstract: The present invention provides structures and methods that enable the construction of micro-LED chiplets formed on a sapphire substrate that can be micro-transfer printed. Such printed structures enable low-cost, high-performance arrays of electrically connected micro-LEDs useful, for example, in display systems. Furthermore, in an embodiment, the electrical contacts for printed LEDs are electrically interconnected in a single set of process steps. In certain embodiments, formation of the printable micro devices begins while the semiconductor structure remains on a substrate. After partially forming the printable micro devices, a handle substrate is attached to the system opposite the substrate such that the system is secured to the handle substrate. The substrate may then be removed and formation of the semiconductor structures is completed. Upon completion, the printable micro devices may be micro transfer printed to a destination substrate.

Abstract: A heterogeneous light-emitter display includes a display substrate having a plurality of pixels disposed thereon. Each pixel including at least a first heterogeneous multiple-component sub-pixel emitting a first color of light and a second sub-pixel emitting a second color of light different from the first color. A heterogeneous light-emitter display can also include an array of heterogeneous pixels. Each heterogeneous pixel includes a plurality of first pixels and a plurality of second pixels. The first sub-pixel of each of the first pixels includes a first light emitter and the first sub-pixel of each of the second pixels includes a second light emitter different from the first light emitter. One or more pixel controllers control the pixels, the first and second pixels, the first and second sub-pixels, and the first and second light emitters.
