1. A redundant pixel layout for a display, comprising:
a display substrate; and
an array of pixels disposed on or over the display substrate, each of the pixels comprising
a first subpixel comprising a first subpixel controller comprising a transistor, the first subpixel controller electrically connected to controller wires, and first light emitters electrically connected to first-light-emitter wires, the first light emitters controlled by the first subpixel controller at least through the first-light-emitter wires, wherein the first light emitters and the first subpixel controller each have a substrate separate and independent of the display substrate and each other and are disposed on a common surface of the display substrate,
a second subpixel comprising (i) a second-subpixel-controller location comprising electrical connections to the controller wires arranged to electrically connect a second subpixel controller comprising a transistor when the second subpixel controller is provided on the common surface of the display substrate and (ii) second-light-emitter locations, each comprising a second-light-emitter wire different from the first-light-emitter wires, electrically connected to the second-subpixel-controller location, and arranged to electrically connect second light emitters when the second light emitters are provided on the common surface of the display substrate, each of the second-light-emitter locations corresponding to a second light emitter that emits light of a same color as one of the first light emitters and of a different color from each other of the second light emitters,
wherein the second subpixel is redundant to the first subpixel,
wherein one of the first light emitters is adjacent to one of the second-light-emitter locations and the one of the first light emitters and the one of the second-light-emitter locations are closer together than are any two first light emitters in different pixels in the array of pixels and are closer together than any first light emitter and second-light-emitter location in different pixels in the array of pixels, and
wherein neither the first sub-pixel controller nor the second sub-pixel-controller location is disposed between any of the first light emitters, between any of the second light-emitter locations, or between any first light emitter and any second light-emitter location in a pixel.
