  • LED DISPLAY WITH WAVELENGTH CONVERSION LAYER
    Publication number: 20170162553
    Abstract: A display and method of manufacture are described. The display may include a substrate including an array of pixels with each pixel including multiple subpixels, and each subpixel within a pixel is designed for a different color emission spectrum. An array of micro LED device pairs are mounted within each subpixel to provide redundancy. An array of wavelength conversion layers comprising phosphor particles are formed over the array of micro LED device pairs for tunable color emission spectrum.
