    摘要： An optical light redirecting film that can be made by microreplication, and that is suitable for use in an autostereoscopic backlight or display, includes opposed first and second structured surfaces. The first structured surface includes lenticular features and the second structured surface includes prismatic features. In some cases, at least a first prismatic feature has a first prism optical axis that is tilted relative to a thickness axis of the film perpendicular to the film plane. In some cases, at least a first lenticular feature has a first lenticular optical axis that is tilted relative to the thickness axis. In some cases, the film may have a central film caliper (thickness) at a central portion of the film and an edge film caliper at a first edge portion of the film, the central film caliper being greater than the edge film caliper.

    摘要： An illumination device comprises a housing (5) with a plurality of compartments (3), each compartment comprising a respective light emission window (15), a light source (11), and a stack of crossed prismatic sheets (10). Light issued by the light source during operation is made to propagate through the prismatic sheets and subsequently through the light emission window. The orientation of the stack of sheets is different for each compartment, thus causing each compartment to issue a different beam of light. The light source of each compartment is separately switchable, thus enabling easy setting of the type of beam issued form the illumination device. Optionally a diffuser (17, 23) is provided at one side or at both sides of the stack of prismatic sheets to enhance the homogeneity of the issued light.

    摘要： A backlight system (30) includes a light emitting section (31) for emitting beams of RGB light and an imaging optical system. A liquid crystal panel (37) is irradiated with the beams of light which have passed through the imaging optical system. The liquid crystal panel (37) includes a plurality of pixels which are arrayed at a pitch (P), each of the plurality of pixels including a plurality of picture elements which correspond to the colors. The imaging optical system includes a first microlens array (MLA1) in which a plurality of lenses (1A) are arrayed at a pitch (P 2 ), and a second microlens array (MLA2) in which a plurality of lenses (2A) are arrayed at a pitch. The lenses (1A) separates the beams of light emitted from the light emitting section (31) by RGB, and causes them to be converged at a pitch same as a pitch at which the picture elements are arrayed. The lenses (2A) are provided in one-to-one correspondence to the picture elements such that lenses (2A) have their respective focal points at positions onto which beams of light having passed through the lenses (1A) are converged. The lenses (2A) deflect the beams of light which have passed through the lenses (1A) in a substantially vertical direction with respect to the display surface of the liquid crystal panel so that the liquid crystal panel (37) is irradiated with the deflected light. This enhances display quality by achieving a high level of efficiency in the utilization of light and further improvements in viewing angle characteristics and a sense of resolution.

    摘要： Optical stack is disclosed. The optical stack includes a first optical stack that includes, a first optical adhesive layer, and a reflective polarizer layer that is disposed on the first optical adhesive layer. The reflective polarizer layer substantially reflects light of a first polarization state and substantially transmits light of a second polarization state orthogonal to the first polarization state. The optical stack also includes a second optical stack that includes a second optical adhesive layer, a low index layer that is disposed on the second optical adhesive layer and includes a plurality of voids dispersed in a binder, and a light directing film that is disposed on the low index layer and includes a plurality of unitary discrete structures. Portions of each unitary discrete structure penetrate into the first optical adhesive layer. Portions of each unitary discrete structure do not penetrate into the first optical adhesive layer. Each unitary discrete structure defines a penetration depth and a penetration base at the interface between the penetrating and non-penetrating portions of the unitary discrete structure. The penetration base has a minimum penetration base dimension. The plurality of unitary discrete structures has an average penetration depth and an average minimum penetration base dimension. The ratio of the average penetration depth to the average minimum penetration base dimension is at least 1.5. The peel strength between the first and second optical stacks is greater than about 30 grams/inch.
