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.

Abstract: The present disclosure provides a display panel including pixel areas arranged in array. The pixel area includes a sub-pixel area and a transparent area arranged in column direction. For two adjacent rows of pixel areas, sub-pixel areas/transparent areas of pixel areas in one row are disposed adjacent to sub-pixel areas/transparent areas of pixel areas in the other row. The sub-pixel area in an odd-numbered row of pixel areas is first sub-pixel area, in which first and second sub-pixels are arranged along row direction. The sub-pixel area in an even-numbered row of pixel areas is second sub-pixel area, in which third and fourth sub-pixels are arranged along row direction. First and third sub-pixels are arranged along column direction, and second and fourth sub-pixels are arranged along column direction. First, second and fourth sub-pixels emit light of different colors, and second and third sub-pixels emit light of a same color.

Abstract: A display panel, a method for manufacturing the display panel, and a display device including the display panel are provided. The display panel includes: a thin film transistor array layer, and a light-emitting function layer at a side of the thin film transistor array layer. The thin film transistor array layer includes a planarization layer, an electrode layer, a first insulation layer, an active layer and a buffer layer. The electrode layer includes at least one first electrode and second electrode, and each first electrode includes a connection portion and an electrode portion which are connected to each other. The light-emitting function layer includes first contact electrodes and light-emitting elements. Heat generated by the light-emitting function layer is conducted to electrode portion of the first electrode through the connection portion of the first electrode and is uniformly distributed on the connection portion and the electrode portion.
