Zusammenfassung:A method of repairing a light emitting device assembly includes providing a light emitting device assembly including a backplane and light emitting devices, where a predominant subset of pixels in the light emitting device assembly includes an empty site for accommodating a repair light emitting device, generating a test map that identifies non-functional light emitting devices in the light emitting device assembly, providing an assembly of a repair head and repair light emitting devices, wherein the repair light emitting devices are located only on locations that are mirror images of empty sites within defective pixels that include non-functional light emitting devices, and transferring the repair light emitting devices from the repair head to the backplane in the empty site in the defective pixels.
