摘要： Optical constructions use a low index of refraction layer (120) disposed between a low absorption layer (101) and a high absorption layer (103) to increase confinement of light to the low absorption region of the optical constructions. Low index layers can be used in optical constructions that have multi-tiered light confinement. In these constructions, a first tier of reflection is provided when light is reflected at the surface of a low index optical film which is disposed directly or indirectly on a light guide (110). A second tier of reflection occurs at the surface of a light redirecting film having appropriately oriented refractive structures.

摘要： A film construction (610) includes a group of microlayers that reflect normally incident light polarized along a first axis more than normally incident light polarized along a second axis. The microlayers are arranged into optical repeat units (ORUs) that have a layer thickness distribution along a thickness axis perpendicular to the first and second axes that provides the group of microlayers with an intermediate reflectivity over an extended reflection band for a given incidence condition. The ORUs include thinner ORUs whose thicknesses are less than an average thickness, and thicker ORUs whose thicknesses are greater than the average thickness. The group of microlayers is optically immersed in a medium having a refractive index greater than air, such that "supercritical light" can propagate through the microlayers. The microlayers are oriented such that, on average, the thinner ORUs are closer than the thicker ORUs to an output surface of the construction. By "supercritical light" is meant that travels through the film at an angle that is more oblique than can be achieved by illumination from air using a flat, smooth air/film interface.
摘要翻译：膜结构（610）包括一组微层，其反射正常入射的光沿着第一轴偏振，而不是沿着第二轴偏振的正常入射光。微层被布置成光学重复单元（ORU），光学重复单元具有沿着垂直于第一和第二轴线的厚度轴线的层厚度分布，其为给定的入射条件在延伸的反射带上提供了一组微层的中间反射率。 ORU包括厚度小于平均厚度的更薄的ORU，以及厚度大于平均厚度的较厚ORU。微组织光学地浸入折射率大于空气的介质中，使得“超临界光”可以通过微层传播。微层的取向使得平均来说，更薄的ORU比较厚的ORU更接近结构的输出表面。 “超临界光”是指以比通过使用平坦，平滑的空气/膜界面的空气照明可以实现的倾斜更倾斜的角度穿过膜。

摘要： A backlight includes nl, n2, and n3 colored LED light sources of a first, second, and third (non-white) color respectively, and a drive circuit connected to these sources. The drive circuit is configured to drive each of the first, second, and third light sources within a specified percentage, such as 10%, of their respective maximum drive characteristics, and the numbers nl, n2, and n3 are selected so that light from the energized first, second, and third LED light sources, when combined, is substantially white. In some cases, the backlight also includes a number n4 of white LED sources, and the colored LED sources may or may not be driven within 10% of their maximum ratings. The number n4 of white sources is selected to increase the brightness of the backlight while maintaining the color gamut of the backlight output within a specified percentage, such as 10%, of a desired specification.

摘要： A front and back reflector are arranged to form a hollow light recycling cavity having an output region, and one or more light sources (e.g. LEDs) are disposed to emit light into the cavity. In one aspect, the back reflector has a design characterized by a first and second parameter. The first design parameter is a ratio of the collective emitting area of the light sources Aemit to the area of the output region Aout, and Aemit/Aout is preferably from 0.0001 to 0.1. The second design parameter is SEP/H, where H is the depth of the recycling cavity, and SEP is an average plan view source separation associated with the light sources. Other aspects of the disclosed extended area light sources are also described.
