The invention provides a micro LED transfer method and an array substrate. A photoresist pattern containing a big-end-down opening is formed on an organic layer of the array substrate, the upper edgeof the opening is smaller or equal to a to-be-transferred light-emitting component, therefore, after a transfer substrate carrying the to-be-transferred light-emitting component is aligned with the array substrate, the to-be-transferred light-emitting component can be firmly clamped in the opening by applying pressure to the transfer substrate, adhesion force of the to-be-transferred light-emitting component to the array substrate is increased, the risk that the to-be-transferred light-emitting component is carried away by the transfer substrate is reduced in a transfer plate removal process is reduced, transfer success rate is increased, product yield is increased, and dark spot defects are avoided.
