Abstract

Embodiments relate to using photocurable polymers to place light emitting diodes (LEDs) onto an electronic display substrate after fabrication of the LEDs. A LED assembly system places LEDs on a temporary substrate after fabrication and applies a a photocurable polymer onto the top surfaces of the LEDs. A transparent pickup head aligns with a subset of the LEDs. The pickup head is positioned on the top surfaces of the subset of LEDs such that the layer of the photocurable polymer is in between the pickup head and the top surface of the subset of the LEDs. Light is directed through the pickup head to cure the photocurable polymer, adhering the subset of LEDs to the pickup head. The subset of LEDs is removed away from the temporary substrate, due to relative movement between the temporary substrate and the pickup head.
