摘要： Self illuminated back and front lit shaped and two-sided signage. The signage includes a turning film having a structured surface for redirecting light and a diffuser providing for diffusion. The shape of the signage from a viewer's perspective provides the content, such as letters, to be conveyed to the viewer. Two-sided signage includes two signs arranged back-to-back, each including a turning film having a structured surface for redirecting light, a diffuser providing for diffusion, and a printed graphic. In the two-sided signage, the turning films receive light from an ambient light source and direct the light via the structured surfaces toward viewers of the two graphics in order to passively illuminate the signage. The two-sided signage can be shaped to provide content via the shape and graphics.

摘要： Articles and methods of making light redirecting film constructions including a microstructured optical film bonded in selected areas to another film, and including a diffuser are described. The diffuser has an optical haze in the range of (20) to (85) percent and an optical clarity of no greater than (50) percent. The diffuser may be a surface diffuser and may be an asymmetric surface diffuser.

摘要： An illumination device, such as a backlight for electronic display devices, is disclosed. The illumination device includes a lightguide optically coupled to a light source, and a viscoelastic layer and a nanovoided polymeric layer are used in conjunction with the lightguide to manage light emitted by the light source. The viscoelastic layer may be a pressure sensitive adhesive.

摘要： Light transmissive non-slip treads coupled to a light directing film having a structured surface for redirecting light oriented on a first axis. The non-slip treads may appear to be specifically illuminated, as if by dedicated light fixtures, but may instead be illuminated by ordinary ambient light.

摘要： The present disclosure relates to articles and methods of making light redirecting film constructions comprising a microstructured optical film bonded in selected areas to another film. This type of assembly may serve various purposes. For example, the assembly may protect the structured film, provide additional functionality, such as diffusion, and/or facilitate attachment of the microstructured optical film to a mounting surface, such as a window.

摘要： Stereoscopic displays and backlights include a light guide with individually addressable light sources disposed at opposite edges of the light guide, and a light redirecting film disposed in front of the light guide. Light from one light source is emitted from the backlight as a right eye elongated light beam, and light from the opposite light source is emitted as a left eye elongated light beam. Structured surface features, e.g. linear prismatic or linear lenticular features, on the light guide and/or the light redirecting film are oriented such that the elongated light beams are offset from an optical axis of the backlight. Moreover, each of the elongated light beams is oriented to intersect both a first observation plane and a second observation plane perpendicular to the first observation plane, the first observation plane defined by the optical axis and an in-plane axis along which the light sources are disposed.
