摘要： A multilayer optical film has a packet of microlayers that selectively reflect light by constructive or destructive interference to provide a first reflective characteristic. At least some of the microlayers are birefringent. A stabilizing layer attaches to and covers the microlayer packet proximate an outer exposed surface of the film. Heating element(s) can physically contact the film to deliver heat to the packet through the stabilizing layer by thermal conduction, at altered region(s) of the film, such that the first reflective characteristic changes to an altered reflective characteristic in the altered region(s) to pattern the film. The stabilizing layer provides sufficient heat conduction to allow heat from the heating elements to change (e.g. reduce) the birefringence of the birefringent microlayers disposed near the outer exposed surface in the altered region(s), while providing sufficient mechanical support to avoid substantial layer distortion of the microlayers near the outer exposed surface in the altered region(s).

摘要： A multilayer optical film (130) has a packet of microlayers that selectively reflect light by constructive or destructive interference to provide a first reflective characteristic. At least some of the microlayers are birefringent. A stabilizing layer attaches to and covers the microlayer packet proximate an outer exposed surface of the film Heating elements (122) can physically contact the film to deliver heat to the packet through the stabilizing layer by thermal conduction, at altered regions of the film, such that the first reflective characteristic changes to an altered reflective characteristic in the altered regions to pattern the film The stabilizing layer provides sufficient heat conduction to allow heat from the heating elements to change (e.g. reduce) the birefringence of the birefringent microlayers disposed near the outer exposed surface in the altered regions, while providing sufficient mechanical support to avoid substantial layer distortion of the microlayers near the outer exposed surface in the altered regions.
