  • Method for manufacturing micro light-emitting diode array substrate
    Patent number: 10964855
    Abstract: A method for manufacturing a micro light-emitting diode array substrate is disclosed. The method includes: providing a drive substrate comprising a plurality of sub-pixel regions, the plurality of sub-pixel regions being configured for bearing micro light-emitting diodes of different colors, and epitaxial layers of the micro light-emitting diodes of different colors having different thicknesses; providing a base substrate, forming a plurality of micro light-emitting diodes on the base substrate, and transferring micro light-emitting diodes of same color on the base substrate as a whole onto the drive substrate; repeating the transferring process in a sequence that the thicknesses of the epitaxial layers of the micro light-emitting diodes gradually increase, until each sub-pixel region in pixel units is provided with one of the micro light-emitting diodes having same color as the each sub-pixel region.
