    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： The instant invention relates to electro-optical switching elements and displays comprising them. In particular, it relates to electro-optical switching elements comprising one or more light conversion means capable to convert light (e.g. ambient light and/or light from a backlight system), wherein each of said light conversion means o is capable to convert the state of polarization of the light from non-polarized light either to linear polarized light or to circular polarized light and, at the same time, o optionally is capable to shift the wavelength of the light to longer values and—at least one of said conversion means o is capable to shift the wavelength of the light to longer values and—a liquid crystal material, which is capable of switching,—one or more means to polarize light, and—optionally a means for illumination such as e.g. a backlight.

    摘要： A display assembly having opposingly disposed display surface and back surface is disclosed herein, which includes a pixel electrode substrate(202) and a common electrode substrate(201). A liquid crystal layer(204) is sandwiched between, and configured to be in a scattering state if an electric field is applied to, the pixel electrode substrate(202) and the common electrode substrate(201). A light source(103) at a lateral side of the display assembly generates, and emits into the display assembly, a linearly polarized light having a first polarization direction. A blocking member(104) disposed at the side of the back surface is configured to block a light having the first polarization direction to, and to allow a light having a second polarization direction perpendicular to the first polarization direction to pass therethrough. A method for manufacturing the display assembly, and a display device including one or two display assemblies are also disclosed.

    摘要： A backlight unit (10), for a display or for general Iighting purposes, has a hollow cavity (16) instead of a solid Iight guide. One or more Iight sources (24a-c), e.g. LEDs, emit Iight into the cavity, which is formed by a front (12) and a back reflector (14). The backlight has either a directly-lit or an edge-lit configuration; it can have a Iarge area and still be thin; it consists of fewer components than conventional devices and its design permits the reuse of Iight reflected internally (Iight recycling). The unit emits Iight of a predefined polarisation and its viewing angle properties can be tailored. Light is uniformly distributed within the guide and the guide's output (20b, 20d) is substantially collimated. Such backlights occupy a specific region in a parameter space defined by two parameters: first, the ratio of the output emission area to the total source emission area should lie in the range from 0.0001 to 0.1 ; and second, the ratio of SEP (an average plan view source separation, which is a measure of the average spacing of the Iight sources in the plane of the unit) to the height of the cavity (H) should be in the range from 3 to 10. There is also a discussion of the required number of light sources N, their arrangement near the periphery of the cavity, as well as the shape and size of the output emission area. The backlight exhibits a minimum brightness uniformity (VESA) value, even when a subset of M adjacent sources is switched off (where M is at least 0.1 N or M>2 or both).
