(A) Schematic illustration of the process for fabricating flexible, white lighting modules, achieved by integrating patterned, encapsulated tiles of YAG:Ce phosphor islands with arrays of InGaN μ-ILEDs. (B) Color chromaticity plotted on a CIE 1931 color space diagram for μ-ILEDs integrated with phosphors with thicknesses of 60 μm, 80 μm, and 105 μm. Optical images of a fully interconnected array of μ-ILEDs (C) without phosphor, (D) with a laminated film of encapsulated YAG:Ce phosphor islands (500 × 500 μm²), and (E) with a laminated diffuser film.
