1. A method of assembling an inorganic light emitting diode (LED) display, the method comprising:
providing a plurality of printable inorganic LEDs in or on one or more native substrates;
transfer printing the plurality of printable inorganic LEDs onto a display substrate separate and distinct from the one or more native substrates to form a plurality of pixels, wherein each of the pixels comprises a set of primary inorganic LEDs and a set of redundant inorganic LEDs;
connecting the primary inorganic LEDs to a display circuit in order to form the display comprising the plurality of pixels;
testing the display to identify defective primary inorganic LEDs in the plurality of pixels; and
establishing an electrical connection to a respective redundant LED of the set of redundant inorganic LEDs in close proximity to each of the defective primary inorganic LEDs so that each of the redundant inorganic LEDs is connected to the display circuit by placing a conductive jumper between the respective redundant LED and the one of the defective primary inorganic LEDs corresponding to the respective redundant LED by micro assembly.
