1. A display formed by sub-displays comprising:

  • a plurality of sub-displays each including;

    an array of light-emitting pixels, each pixel including at least one light-emitting element formed on a first side of a semiconductor substrate, the at least one light-emitting element comprising multiple layers epitaxially grown on a semiconductor surface of the semiconductor substrate on the first side;

    integrated circuits formed on a second side of the semiconductor substrate;

    conductive electrodes penetrating through the semiconductor substrate and coupling the light-emitting elements of the array of light-emitting pixels on the first side to the integrated circuits on the second side; and

    a conductive grid array package formed on the second side of the semiconductor substrate and conductively coupled to the integrated circuits; and

    interconnects conductively coupled to the conductive grid array packages of the plurality of sub-displays.
