Abstract: Optical constructions are disclosed. A disclosed optical construction includes a reflective polarizer layer, and an optical film that is disposed on the reflective polarizer layer. The optical film has an optical haze that is not less than about 50%. Substantial portions of each two neighboring major surfaces in the optical construction are in physical contact with each other. The optical construction has an axial luminance gain that is not less than about 1.2.

Abstract: The present disclosure generally relates to patterned gradient polymer films and methods for making the same, and more particularly to patterned gradient optical films that have regions that include variations in optical properties such as refractive index, haze, transmission, clarity, or a combination thereof. The variation in optical properties can occur across a transverse plane of the film as well as through a thickness direction of the film.

Abstract: Optical films for redirecting light are described, and optical systems, such as display systems, incorporating such optical films are described. The optical film may include a first structured surface including a plurality of prismatic structures, and a second structured surface opposing the first structured surface and including a plurality of microstructures. An effective transmission of the optical film is not more than 1% less than a film with a comparable construction except for a smooth, non-structured second surface.

Abstract: Optical films, optical stacks including the optical films, and display systems including the optical films are described. The optical film includes a first major surface that may include a plurality of first microstructures that extend along a first direction. The optical film also includes a second major surface that is opposite to the first major surface and includes a plurality of second microstructures. The second major surface has an optical haze that is not greater than about 3% and an optical clarity that is not greater than about 85%.

Abstract: A lightguide defines an optical axis and has an optical absorption coefficient of at least 0.02 cm−1 at a wavelength of 500 nm. The light guide includes a plurality of discrete light extracting structures, each with a first surface configured to extract light propagating in a first direction along the light guide, a second surface configured to extract light propagating in a second direction along the light guide, and a light extraction efficiency of less than 2%. The first surface and the second surface in each of the light extracting structures making an angle with each other larger than 90 degrees; the angle between the first and second surfaces of at least one of the light extracting structures being different from the angle between the first and second surfaces of at least another one of the light extracting structures.

Abstract: A lightguide is disclosed. The lightguide is centered on an optical axis and includes a plurality of light extracting structures next to and spaced apart from each other. Each structure includes a surface that extends from a first side of the lightguide and is adapted to extract light that propagates in a first direction along the optical axis from an opposite second side of the lightguide by reflecting the propagating light toward the second side. The surface makes an angle with the optical axis that is less than 45 degrees and greater than 10 degrees.
