    摘要： A multilayer optical film body includes a first and second packet of microlayers. Each packet partially transmits and partially reflects light over an extended wavelength range, such as the visible region, for normally incident light polarized along a first principal axis of the film body. In combination, the first and second packets have an intermediate reflection and transmission (e.g. 5-95% internal transmission, on average) for the normally incident light, and similar intermediate reflection/transmission (e.g. 10-90% internal transmission, on average) for oblique light. The packets are laminated or otherwise connected so that light can pass through the packets sequentially. In at least a first test area of the film body, a high frequency spectral variability of the combination of packets is less than a high frequency spectral variability of the first packet by itself, and may also be less than a high frequency spectral variability of the second packet by itself.

    摘要： Multilayer reflecting polarizing films are disclosed having increased in-plane refractive index differences between adjacent microlayers along both the pass and block axis, and having negative refractive index differences between adjacent microlayers along the thickness or z-axis. Major front and back surfaces of the film exposed to air provide a Fresnel reflectivity component to the pass axis reflectivity, and the microlayers provide a microlayer component to the pass axis reflectivity, such microlayer component preferably having a reflectivity of p-polarized light that increases with incidence angle faster than the Fresnel reflectivity component decreases so as to substantially avoid off-axis gain peaks for p-polarized light. The films preferably utilize a relatively small total number of microlayers, arranged in a single coherent stack with monotonic optical repeat unit thickness profile, and at least some microlayers preferably include polyethylene naphthalate or a copolymer thereof.

    摘要： A direct-lit backlight includes a diffuse reflector disposed in front of a light source. The diffuse reflector has a continuous phase material and a disperse phase material, at least one of which is birefringent, and the disperse phase material is formed into particles having a transverse dimension less than 1 micrometer for efficient visible light scattering. The continuous and disperse phases have refractive indices tailored so the diffuse reflector transmits light from the light source substantially more strongly for obliquely incident light than for normally incident light to provide bulb-hiding characteristics.
