1. A display panel with redundancy scheme comprising:

  • a display substrate including a pixel area that includes an array of subpixels, an array of redundant pairs of landing areas, an array of redundant LED bonding site pairs, and an array of redundant LED device pairs;

    wherein each subpixel in the array of subpixels is designed for a redundant primary color emission, and each subpixel includes a redundant pair of landing areas and a corresponding LED bonding site pair on the redundant pair of landing areas to receive a corresponding redundant LED device pair;

    wherein the array of subpixels includes an array of first subpixels designed for a first primary color emission, an array of second subpixels designed for a second primary color emission different from the first primary color emission, and an array of third subpixels designed for a third primary color emission different from the first and second primary color emissions;

    circuitry to switch and drive the array of subpixels; and

    one or more LED device irregularities among the array of redundant LED device pairs, wherein each corresponding landing area containing an LED device irregularity is electrically disconnected from the circuitry.
