摘要： A reflective film includes interior layers that selectively reflect light by constructive or destructive interference, the layers extending from a first to a second zone of the film. In the first zone, the layers operate substantially as a reflective polarizer; in the second zone they operate substantially as a mirror. The layers may thus provide a first reflective characteristic in the first zone wherein normally incident light of one polarization state is substantially reflected and normally incident light of an orthogonal polarization state is substantially transmitted, and a second reflective characteristic in the second zone wherein normally incident light of any polarization state is substantially reflected. The film may have a first thickness in the first zone that is substantially the same as a second thickness in the second zone. Alternatively, the second thickness may be substantially less than the first thickness. Related methods, articles, and systems are also disclosed.

摘要： Multi-layer articles are described that are capable of forming color images. The articles may contain at least two layers, a thermally activatable layer and a blocking layer, or at least three layers with two thermally activatable layers and a blocking layer between. The thermally activatable layers absorb light of a write wavelength and have an absorption threshold for activation. The blocking layer blocks light of the write wavelength at certain incident angles or polarization states and permits light of the write wavelength and certain incident angles or polarization states to pass through. The thermally activatable layers may be layers with a light to heat convertor composition and a color changing compound or they may be a group of layers arranged to change its reflective characteristic upon exposure to light while maintaining the structural integrity of the group of layers

摘要： A diffusely reflective optical film includes a blended layer extending from a first to a second zone of the film. The blended layer includes first and second polymer materials separated into distinct first and second phases, respectively. The blended layer may have the same composition and thickness in the first and second zones, but different first and second diffusely reflective characteristics in the first and second zones, respectively. The difference between the first and second diffusely reflective characteristics may not be attributable to any difference in composition or thickness of the layer between the first and second zones. Instead, the difference between the first and second diffusely reflective characteristic may be attributable to a difference in birefringence of the first and/or second polymer materials between the first and second zones. The blend morphology of the blended layer may be substantially the same in the first and second zones.

摘要： Certain patternable reflective films are used as masks to make other patterned articles, and one or more initial masks can be used to pattern the patternable reflective films. An exemplary patternable reflective film has an absorption characteristic suitable to, upon exposure to a radiant beam, absorptively heat a portion of the film by an amount sufficient to change a first reflective characteristic to a different second reflective characteristic. The change from the first to the second reflective characteristic is attributable to a change in birefringence of one or more layers or materials of the patternable film. In a related article, a mask is attached to such a patternable reflective film. The mask may have opaque portions and light-transmissive portions. Further, the mask may have light-transmissive portions with structures such as focusing elements and/or prismatic elements.

摘要： A reflective film includes a first optical stack that provides a first reflective characteristic and a second optical stack that provides a second reflective characteristic. The optical stacks also have first and second absorptive characteristics that are suitable to absorptively heat the respective stacks upon exposure to light including a write wavelength while maintaining the structural integrity of the stacks. The absorptive heating can change the first and second reflective characteristics to third and fourth reflective characteristics, respectively. A blocking layer that at least partially blocks light of the write wavelength may also be provided between the optical stacks to permit absorptive heating of any selected one of the optical stacks. The reflective characteristics of the optical stacks can thus be independently modified in any desired patterns by appropriate delivery of light beams that include the write wavelength.

摘要： An article for use in light spreading includes a body having first and second surfaces, and first and second in-plane axes that are orthogonal with respect to each other and a third axis that is mutually orthogonal to the first and second in-plane axes in a thickness direction of the body. A portion of the first surface is a birefringent structured surface. The portion is structured such that, when the article receives a light signal within a particular range of wavelengths, the structured surface causes splitting the light signal into a plurality of divergent light signals. The article can be used for color mixing such as in a cavity providing a backlight for LCD devices or other display devices requiring a backlight.

摘要： A retarder film provides a first light retardation and can be heat processed in one or more selected areas to provide a second light retardation in the selected area(s). The retarder film may have an absorption characteristic such that the heat processing can be carried out by selectively exposing the film to a suitable radiant beam. The retarder film is composed of a stack of contiguous ultrathin layers configured to provide an effective optical medium for visible light. Visible light propagates through the stack as an effective medium having effective refractive indices along principal x-, y-, and z-axes. At least some of the ultrathin layers possess intrinsic birefringence, and the effective indices of the stack are functions of the intrinsic refractive indices of the constituent ultrathin layers. The heat processing is carried out so that the ultrathin layer stack structural integrity is not substantially altered in the processed area(s).
