Abstract: A repairing method for micro-LED chip defective pixels is disclosed. By providing a main recess and a backup recess in each of sub-pixel areas of a substrate, wherein each of the main recesses is loaded with a main micro-LED chip, when all of the main micro-LED chips are detected for defective pixels, the backup recess in each of the sub-pixel areas where the defective pixel is detected is loaded with a backup micro-LED chip using a fluid mass transfer method, which improves the repair efficiency.

Abstract: A display panel, a manufacturing method thereof, and a display device are provided. The display panel includes a driving backplate, functional component groups, and micro-LED chips. The functional component groups are integrated in regions where the micro-LED chips are not disposed and are multiplexed as alignment marks. In a mass transfer process of the micro-LED chips, the alignment marks are prevented from additionally occupying pixel space by using part of functional components multiplexed as the alignment marks under a precondition of ensuring alignment accuracy.
