  • Patent number: 11728318
    Abstract: A method for assembling an LED apparatus using an epitaxial layered structure comprising a first-type doped semiconductor layer, a second-type doped semiconductor layer, and an active layer between the doped semiconductor layers. The method involves depositing a conductive layer adjacent to and in ohmic contact with the first-type doped semiconductor layer. After forming a pattern masked layer on the conductive layer to expose one or more unprotected mask regions, the unprotected mask region(s) are processed to form a micropixellated structure having micropixel contact areas that are electrically isolated from each other. The method further involves placing a first contact pad over the micropixellated structure to overlap the micropixel contact areas and form a first electrode shared by a set of micro-LEDs. The micropixellated structure is also electrically coupled to a second contact pad that forms a second electrode shared by the set of micro-LEDs.
