  • Patent number: 10985302
    Abstract: A system and method are provided for repairing an emissive display. Following assembly, the emissive substrate is inspected to determine defective array sites, and defect items are removed using a pick-and-remove process. In one aspect, the emissive substrate includes an array of wells, with emissive elements located in the wells, but not electrically connected to the emissive substrate. If the emissive elements are light emitting diodes (LEDs), then the emissive substrate is exposed to ultraviolet illumination to photoexcite the array of LED, so that LED illumination can be measured to determine defective array sites. The defect items may be determined to be misaligned, mis-located, or non-functional emissive elements, or debris. Subsequent to determining these defect items, the robotic pick-and-remove process is used to remove them. The pick-and-remove process can also be repurposed to populate empty wells with replacement emissive elements.
