R‐G‐B light emitting diode on silicon (LEDoS) micro‐displays were fabricated and the world's first full color 3LED projection prototype is presented. LEDoS micro‐displays were realized by flip‐chip bonding of LED micro‐arrays on silicon CMOS active‐matrix drivers. Using trichroic prism, images generated from three self‐emissive R‐G‐B LEDoS micro‐displays were combined to form a color image, demonstrating great potential for high efficiency and high brightness projection applications.
