  • Patent number: 12068443
    Abstract: Embodiments relate to forming an elastomeric interface layer (elayer) with a flap over multiple light emitting diode (LED) dies by forming materials across multiple LED dies and removing the materials between the LED dies. The formed flap of the elayer provides a large surface area for adhesion between each LED and a pick-up surface. For example, the flap may have a surface area that is larger than the light emitting surface of the LED die, or larger than the surface area of an elastomeric interface layer without the flap. As such, the elayer allows each LED to be picked up by a pick-up surface and placed onto a display substrate including control circuits for sub-pixels of an electronic display. In some embodiments, the LED dies are micro-LED (?LED) dies.
