Abstract
A Micro LED transferring method, a Micro LED display panel and a Micro LED display device are provided. The Micro LED display panel includes a substrate, a pixel defining layer including multiple openings, first conducting layer located in the multiple openings, photosensitive conductive bonding layers and Micro LED structures. The photosensitive conductive bonding layer is solidified after receiving light, such that elements adhered on two opposite surfaces of the photosensitive conductive bonding layer are bonded together. Due to the photosensitive conductive bonding layer, a Micro LED is detected during a transferring process rather than after a bonding process, thereby eliminating a step of removing a bonded abnormal Micro LED, thus simplifying the detecting and repairing processes of Micro LEDs.
