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: Optical diffusing films are made by microreplication from a structured surface tool. The tool is made using a 2-part electroplating process, wherein a first electroplating procedure forms a first metal layer with a first major surface, and a second electroplating procedure forms a second metal layer on the first metal layer, the second metal layer having a second major surface with a smaller average roughness than that of the first major surface. The second major surface can function as the structured surface of the tool. A replica of this surface can then be made in a major surface of an optical film to provide light diffusing properties. The structured surface and/or its constituent structures can be characterized in terms of various parameters such as optical haze, optical clarity, Fourier power spectra of the topography along orthogonal in-plane directions, ridge length per unit area, equivalent circular diameter (ECD), and/or aspect ratio.

Abstract: An optical element including an array of microlenses, a pinhole mask, and a wavelength selective filter is described. The pinhole mask includes an array of pinholes with each pinhole in the array of pinholes aligned with a microlens in the first array of microlenses. The wavelength selective filter is adapted to transmit a first light ray having a first wavelength and transmitted from a first microlens in the array of microlenses through a first pinhole in the array of pinholes aligned with the first microlens, and to attenuate a second light ray having the first wavelength and transmitted from the first microlens through a second pinhole in the array of pinholes aligned with a second microlens in the first array of microlenses adjacent to the first microlens.
