20160107471 | NANOSTRUCTURE ARRAY DIFFRACTIVE OPTICS FOR RGB AND CMYK COLOR DISPLAYS - An RGB and/or CMYK full color optical display device comprising multiple nanostructure arrays configured to provide display of a wide range of colors corresponding to multiple pixels or sub-regions of an image is disclosed, where the multiple nanostructure arrays may be formed on a single substrate layer. An optical display device includes a substrate having a surface, and a first pixel of a color image comprising first and second sub-pixels according to at least one of an additive and subtractive color scheme, where the first sub-pixel comprises a first optical sub-wavelength nanostructure array formed on or in the surface of the substrate, and where the second sub-pixel comprises a second optical sub-wavelength nanostructure array formed on or in the surface of the substrate. A method of manufacturing an RGB and/or CMYK full color optical display comprising multiple nanostructure arrays arranged as sub-pixels according to a color scheme is also disclosed. | 04-21-2016 |
20120038463 | SECURITY DOCUMENT WITH ELECTROACTIVE POLYMER POWER SOURCE AND NANO-OPTICAL DISPLAY - A security document is disclosed which includes an electrical circuit embedded in a document substrate, where the electrical circuit includes a power source with at least one electroactive polymer power generator, and an optical display including at least one electroluminescent display element and at least one nanohole array which forms a layer of the electroluminescent display element. Security features comprising nanohole arrays are also provided. A method of authenticating a security document is disclosed, including illuminating an encoded nanohole array in the security document with a focused light beam or laser light source emitting at least one defined wavelength of incident light, detecting a transmitted portion of the incident light transmitted through the nanohole array with an optoelectronic sensor, analyzing at least one wavelength of the transmitted portion of light to produce a detected signal, and comparing the detected signal with an authentication signal to authenticate the security document. | 02-16-2012 |
