Claim 18:
19. The manufacturing method of a display panel according to claim 18, wherein on the plane parallel to the plane where the base substrate is located and along the direction from the center of the base substrate to the edge of the base substrate, the distance between the centers of the adjacent two of the plurality of bonding electrodes gradually increases; and
the manufacturing method of a display panel further comprises:
defining a standard array structure comprising a plurality of standard bonding positions on the plane where the base substrate is located; wherein the plurality of standard bonding positions and the plurality of Micro-LEDs of the chip array are in one-to-one correspondence and each of the plurality of standard bonding positions has a same size; and a distance between centers of adjacent two of the plurality of standard bonding positions is same as a distance between adjacent Micro-LEDs; and
performing simulated stretch to the standard array structure according to an expansion coefficient of the transfer material to obtain a target array structure; wherein in the target array structure, along the direction from the center of the base substrate to the edge of the base substrate, a distance between centers of adjacent two of the plurality of bonding positions gradually increases; and
obtaining the base substrate comprises: disposing the plurality of the bonding electrodes on the base substrate in one-to-one correspondence to the plurality of bonding positions in the target array structure.
