Abstract
Methods for rapidly fabricating color image display for any given color image from a prefabricated generic stamp comprising arrays of structural pixels. The pixels are composed of micro-gratings and/or sub-wavelength structures that give structural colors. Different methods based on micro-patterning techniques may be used to fabricate the color image display devices, including: 1) selectively masking the generic stamp and imprinting from the masked stamp; 2) imprinting from the generic stamp and thermal-optical patterning on an imprinted layer. The fabricated color image display device can further function as a stand-alone display device or a color image stamp for replicating multiple color image display devices.
