Publication number: 20240153927Abstract: 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 ?m to 50 ?m), 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.Type: ApplicationFiled: November 13, 2023Publication date: May 9, 2024Inventors: Christopher Bower, Matthew Meitl, David Gomez, Salvatore Bonafede, David Kneeburg, Alin Fecioru, Carl Prevatte

Publication number: 20240105698Abstract: An example of a pixel module comprises a module substrate having light emitters disposed on a light-emitter surface and a controller disposed on a controller surface opposed to the light-emitter surface. At least one module electrode is electrically connected to the controller and at least one module electrode is electrically connected to each light emitter. An example of a pixel-module wafer comprises a module source wafer comprising sacrificial portions and module anchors, each sacrificial portion laterally separated from an adjacent sacrificial portion by a module anchor and a pixel module disposed entirely over each sacrificial portion. At least one module tether physically connects each of the pixel modules to at least one of the module anchors.
