    Abstract: A microreplicated optical film (919) for use in optical displays, backlights, and the like includes a prismatic layer (950) carried by a substrate (920). In use, the optical film may be combined in a system with other components such that the optical film is positioned between an extended light source (902) and a polarizer (904). In such cases, if the substrate has an appreciable birefringence, a subtle but characteristic colored pattern known as substrate color mura (SCM) may be detected by a user of the system. To reduce or eliminate the SCM with little or no adverse effect on brightness enhancement capabilities of the optical film, the optical film may include an embedded structured surface (933) between the substrate and the prismatic layer. In order to avoid another optical artifact known as sparkle, at least 80% of the embedded structured surface is preferably occupied by features such as defocusing lenslets or random planar facets.

    Abstract: A backlight system includes an extended area light guide (120) and crossed first (128) and second (130) prismatic recycling films. The light guide provides a first light distribution that has a maximum luminance at a first polar angle, e.g., from 70 to 90 degrees, relative to the optical axis (116) of the system. The recycling films provide a second light distribution. No diffuser film is provided between the light guide and the recycling film disposed nearest the light guide. Instead, light is specularly transmitted from the output surf ace (120a) of the light guide to the input surf ace (128a) of the recycling film nearest the light guide. The recycling films comprise prisms having refractive indices tailored to provide the second light distribution with a maximum luminance at a polar angle of 10 degrees or less. The prisms preferably have a refractive index from 1.63 to 1.76. Related methods and articles are also disclosed.

    Abstract: A brightness enhancement film includes a plurality of linear prisms disposed on a birefringent substrate. A light ray that enters the film from the substrate side and exits the film from the linear prisms side undergoes substantially a same phase retardation for mutually orthogonal polarization states while travelling within the film. The light ray exits the film at an angle from a normal to the substrate that is greater than 20 degrees.
