摘要： A display system includes a reflective display panel and a light source tailored to enhance the color gamut of the system. The panel, which may be a Cholesteric liquid crystal display panel, includes an array of reflective pixels, each pixel comprising a first, second, and third subpixel of different first, second, and third colors. The light source illuminates a front of the display panel with source light to enable observers to view images formed by the panel. The light source includes a lamp and an enhancing element. The lamp, which may be a metal halide lamp, emits lamp light that includes the first, second, and third colors. The enhancing element may be an optical filter, a supplemental LED light source or other light source, or both. The enhancing element enhances the system color gamut, for example, by increasing the color gamut area relative to illumination with the lamp alone.

摘要： Low loss, high reflectivity wide band mirror films provide a desired mix of specular reflection and diffuse reflection or scattering to provide semi-specular reflectivity. The mirror films generally include both a specularly reflective multilayer optical film (MOF) having a wide reflection band, and a scattering layer. In some cases a low refractive index TIR layer is sandwiched between the MOF and the scattering layer. In other cases the scattering layer contacts the MOF directly. In embodiments that include the TIR layer, the TIR layer preferably has a nanovoided morphology and includes a plurality of particles and a polymer binder. In embodiments wherein the scattering layer contacts the MOF directly, the scattering layer preferably also has a nanovoided morphology and includes a plurality of particles and a polymer binder.

摘要： An optical stack (400) having a plurality of alternating polymeric layers (401, 402) is described. The alternating layers may be alternating birefringent (syndiotactic polystyrene, sPS) and isotropic (CoPENa) layers, or alternating positively and negatively birefringent layers. Birefringent layers are made using polymers which form optically symmetrical crystallites upon stretching of the polymer. The optical stack has a large refractive index difference in the x- direction (the stretching direction) and small refractive index differences in the y- and z-directions (the non - stretching directions). The optical stack can be made using standard film tentering methods and may be a multilayer reflective polarizer.

摘要： A LED package including an LED that emits excitation light at an excitation light wavelength and a layer of phosphor material positioned to receive the excitation light and having a first index of refraction at the excitation light wavelength. The phosphor material emits visible light at a visible light wavelength when illuminated with the excitation light. An interference reflector is positioned adjacent to the layer of phosphor material and a TIR promoting layer is in contact with the layer of phosphor material. The TIR promoting layer has a second index of refraction at the excitation light wavelength that is less than the first index of refraction at the excitation light wavelength.

摘要： A photosensitive element (5) includes a layer of a photosensitive material (10) on a transparent, multilayer, polymeric support (20, 22) having numerous alternating layers of two different polymeric materials. A polymeric multilayer reflector (22) reflects at least 50% of actinic radiation in the range of wavelengths to which the photosensitive material (10) is sensitive. If the polymeric multilayer reflector (22) includes numerous, thin, alternating layers located at the surface of the polymeric support (20, 22) closest to the photosensitive material (42), the element not only provides increased speed but also provides an antihalation effect. In another aspect, a multilayer reflector (22) is located a distance removed from the photosensitive layer (10) sufficient to reduce any woodgrain that would otherwise occur, while increasing speed.

摘要： A broadband mirror, polarizer, or other reflector includes at least one stack of microlayers. Microlayers in the stack are arranged into optical repeat units. At a design angle of incidence such as normal incidence, the stack provides a 1
st order reflection band, a 2
nd order reflection band, and optionally a 3
rd order reflection band. The 2
nd order reflection band overlaps, or substantially overlaps, the 1
st and/or 3
rd order reflection bands to form a single wide reflection band. The wide reflection band may include the 2
nd and 1
st but not a 3
rd order reflection band, or the 2
nd and 3
rd but not the 1
st order reflection band, or it may include the 1
st , 2
nd , and 3
rd order reflection bands, as well as still higher order reflection bands. The wide reflection band may cover at least a portion of visible and infrared wavelengths.摘要翻译： 宽带反射镜，偏振器或其他反射器包括至少一个微层堆叠。 堆叠中的微层被排列成光学重复单元。 在诸如法向入射的设计入射角处，堆叠提供第一阶反射带，第二阶反射带和可选的第三阶反射带。 二阶反射带与第一和/或第三阶反射带重叠或基本重叠以形成单个宽反射带。 宽反射带可以包括第二和第一而不是第三级反射带，或者第二和第三而不是第一级反射带，或者它可以包括第一，第二和第三反射带 rd阶反射带，以及更高阶的反射带。 宽反射带可以覆盖可见光和红外波长的至少一部分。
