Claim 17:
18. A manufacturing method of a display panel, comprising:
obtaining a base substrate, wherein a plurality of bonding electrodes are disposed on the base substrate; and on a plane parallel to a plane where the base substrate is located and along a direction from a center of the base substrate to an edge of the base substrate, a size of each of the plurality of bonding electrodes gradually increases, or a distance between centers of adjacent two of the plurality of bonding electrodes gradually increases;
obtaining a plurality of micro light emitting displays (Micro-LEDs) disposed in an array on a transfer substrate, wherein the plurality of Micro-LEDs and the transfer substrate are attached through a transfer material; the transfer material is a thermal expandable material; the plurality of Micro-LEDs form a chip array on the transfer substrate; each of the plurality of Micro-LED has a same size; and distances between adjacent Micro-LEDs are the same; and
bonding each of the plurality of Micro-LEDs with a corresponding bonding electrode, so that after each of the plurality of Micro-LEDs is offset due to the transfer material, each of the plurality of Micro-LEDs are bonded with the corresponding bonding electrode.
