20150124306 | ULTRATHIN NANOSTRUCTURED METALS FOR HIGHLY TRANSMISSIVE PLASMONIC SUBTRACTIVE COLOR FILTERS - An ultrathin plasmonic subtractive color filter in one embodiment includes a transparent substrate and an ultrathin nano-patterned film formed on the substrate. A plurality of elongated parallel nanoslits is formed through the film defining a nanograting. The nanoslits may be spaced apart at a pitch selected to transmit a wavelength of light. The film is formed of a material having a thickness selected, such that when illuminated by incident light, surface plasmon resonances are excited at top and bottom surfaces of the film which interact and couple to form hybrid plasmon modes. The film changes between colored and transparent states when alternatingly illuminated with TM-polarized light or TE-polarized light, respectively. In one configuration, an array of nanogratings may be disposed on the substrate to form a transparent display system. | 05-07-2015 |
20150298622 | METHOD FOR REDUCING REFLECTANCE OF BRIGHT DECORATIVE TRIM UNDER HIGH AMBIENT LIGHT CONDITIONS - In a dimmable trim component for a vehicle interior, a trim article includes a reflective member having a photoreactive or an electro-optic coating disposed over the reflective member. The reflective member is configured to reflect ambient light. The coating is a bistable coating and is operable between a first light transmissive state and a second light transmissive state. When in the first light transmissive state, ambient light is transmitted to the reflective member for reflection by the reflective member through the coating. When in the second light transmissive state, a portion of the ambient light is absorbed by the coating and therefore, not reflected by the reflective member, such that the coating provides a dimming effect to the trim article in high ambient conditions. | 10-22-2015 |
