20080225422Optical Filter - An optical filter for filtering light rays having mutually different light intensity and direction of incidence on the optical filter along a number of mutually different directions and having a predetermined wavelength or wavelengths, has a carrier body which is transmissive for light rays having the predetermined wavelength or wavelengths and a plurality of photo-adaptive light-blocking elements distributed within the carrier body rendering the optical filter least transmissive in the direction along which the light ray having the highest light intensity is incident.09-18-2008
20130148221NON-DICHROIC OMNIDIRECTIONAL STRUCTURAL COLOR - A non-dichroic omnidirectional structural color multilayer structure. The non-dichroic omnidirectional structural color multilayer structure has an absorbing layer, a first layer extending across the absorbing layer, and a second layer extending across the first layer. The multilayer structure can reflect a narrow band of electromagnetic radiation that has a width of less than 500 nanometers and a center wavelength shift of less than 200 nanometers when the multilayer structure is viewed from angles between 0 and 45 degrees. In addition, the absorbing layer can block electromagnetic radiation reflected off of a surface that is proximate to the multilayer structure and thereby afford for a “pure” color that is not contaminated by reflected light from surrounding surfaces.06-13-2013
20120281303DISPLAY DEVICE AND LIGHT SENSING SYSTEM - A display device is applied to a light sensing system. The display device includes a display module and a pattern layer. The pattern layer is made of optical material capable of either fully or partially reflecting or absorbing invisible light of specific wavelength emitted from the display module, and is formatted on the display module, thus defining gaps through which invisible light can pass. A light sensor is utilized to sense the pre-determined pattern defined by the invisible light passing through the pattern layer. Based on the light sensing result, the light sensor can recognize the corresponding pattern. The optical material of the pattern layer may be arranged to incorporate locational varying invisible light transmittance to define the pre-determined pattern at a finer degree, thus further increasing sensing accuracy.11-08-2012
