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.

Methods for fabricating color image display devices comprising structural color pixels from a generic stamp

A display media including a pixel layer containing subpixels for different optical bands composed of nano-scale structures and an intensity control layer that can pattern the luminance of the subpixels. The display media includes a substrate layer, a sub-wavelength substrate supported by the substrate layer and including subpixels, each subpixel defined by at least one sub-wavelength structure having at least one specific optical property including a specific optical band, at least two of the subpixels having a different specific optical property, and an intensity control layer to individually control an amount of luminance of each individual subpixel in a pattern. Some of the subpixels may have colors that define a color space, while some other subpixels may have an invisible radiation spectrum band. For example, the display media can allow both overt information (color images) and covert information to be embedded together with high density.
