Abstract
A display panel and method of manufacture are described. In an embodiment, a display substrate includes a pixel area and a non-pixel area. An array of subpixels and corresponding array of bottom electrodes are in the pixel area. An array of micro LED devices are bonded to the array of bottom electrodes. One or more top electrode layers are formed in electrical contact with the array of micro LED devices. In one embodiment a redundant pair of micro LED devices are bonded to the array of bottom electrodes. In one embodiment, the array of micro LED devices are imaged to detect irregularities.

A display panel with redundancy scheme comprising:
- a display substrate including a pixel area and a non-pixel area, wherein the pixel area includes an array of subpixels and a corresponding array of bottom electrodes within the array of subpixels;
- an array of redundant micro LED device pairs bonded to the array of bottom electrodes, wherein each subpixel includes a bottom electrode and a redundant micro LED device pair bonded to the bottom electrode, and each redundant micro LED device pair within a respective subpixel is designed to emit a same primary color emission;
- and one or more top electrode layers in electrical contact with the array of redundant micro LED device pairs;
- wherein the array of redundant micro LED device pairs comprises a first array of redundant micro LED device pairs, a second array of redundant micro LED device pairs, and a third array of redundant micro LED device pairs, wherein the first, second, and third arrays of redundant micro LED device pairs are designed to emit different primary color emissions.
