We demonstrate a scalable fabrication method for microLED displays using photopatternable InP-based QDs. Using photosensitive ligands, we demonstrate pixel resolutions of 10 μm with EQE of >40% in <10 μm thickness. Accelerated reliability is measured and modeled to calculate an expected lifetime of >10k hours for direct-view microLED operating conditions.
