Claim 11:
12. The display panel according to claim 10, wherein a plurality of standard annular structures are defined on the plane where the base substrate is located; each of the plurality of standard annular structures comprises a plurality of standard bonding positions; each of the plurality of standard bonding positions has a same size; and along the direction from the center of the base substrate to the annular structure, a distance between centers of adjacent two of the plurality of standard bonding positions is Dm; and
each of the annular structure comprises bonding electrodes in one-to-one correspondence to the plurality of standard bonding positions; along the direction from the center of the base substrate to the annular structure, an offset from a center of an n-th bonding electrode to a center of an n-th standard bonding position is Cmn satisfying: Cmn=k×Dmn, wherein k is a linear expansion coefficient of a transfer material for bonding the plurality of Micro-LEDs, and Dxn=n×Dm.
