  • Patent number: 8964295
    Abstract: Techniques are described for designing and manufacturing a refractive surface that produces a desired image when placed over a target image. The refractive lens surface may include a set of lens patches, each of which indexes a region on the source image to refract light from the indexed region to recreate a patch of the target image. And together, the lenses reproduce the target image. In one embodiment, the refractive geometry of the lens surface (i.e., the shape of each lens) is determined by formulating and efficiently determining a solution to an inverse light transport problem. The solution may account for additional constraints imposed by the physical manufacturing procedure. Doing so results in a design for a refractive surface amenable to milling (or other manufacturing process).

    Abstract: A micro-lens enhanced element comprises a substrate bearing sequences of printed image elements, each sequence containing image elements from more than one image. A transparent spacer layer is coated over the interlaced image strips. Lenticular lenses are fashioned over each sequence of image elements by deposition of a transparent layer of low surface energy polydimethyl siloxane based material and ablation of the same to create strips of material abhesive to a polymeric lens forming material between consecutive sequences of printed image elements. During deposition of a liquid lens forming material, the liquid withdraws from the liquid abhesive low surface energy strips to form a meniscus, thereby providing lenticular lenses. The transparent low surface energy material comprises a near infrared dye with low absorption in the visible range of the spectrum to render the material both transparent and ablateable by infrared laser.

  • Patent number: 8169699
    Abstract: Polarization preserving projection screens provide optimum polarization preservation for 3D viewing. The projection screens additionally provide improved light control for enhanced brightness, uniformity, and contrast for both 2D and 3D systems. Generally, the disclosed method for providing a projection screen comprises stripping an optically functional material from a carrier substrate, thus creating engineered particles from the optically functional material. The engineered particles may then be deposited on a second substrate to create a substantially homogeneous optical appearance of the projection screen.

  • Patent number: 8134781
    Abstract: There is provided an optical film for backlight units or illuminators. The optical film comprises a light-incident portion and a light exit portion. Here, the optical film is characterized in that it comprises a plurality of protrusions formed on at least one of the light-incident portion and the light exit portion, wherein a plurality of the protrusions satisfies the requirements of the following Equation: 80×H1/3?P?200×H1/3 and 0.I×D?H?D, provided that a mean diameter of protrusions is represented by ‘D’, a mean height of protrusions is represented by 1H?, and a mean distance between adjacent protrusions is represented by ‘P’. Therefore, the optical film may be useful to suppress blocking between films and the formation of surface defects, which are caused by the Moire, Newton ring and wet-out phenomena, without degrading the brightness.

  • Publication number: 20120013851
    Abstract: A light diffusing optical construction is disclosed. The optical construction includes an asymmetric optical diffuser that scatters light in a first direction with a first viewing angle AH and in a second direction orthogonal to the first direction with a second viewing angle AV. The ratio AH/AV is at least about 2. The optical construction also includes a substantially specular reflector that reflects light that is not scattered by the asymmetric optical diffuser. The substantially specular reflector has a first average reflectance Ro in the visible at a substantially zero incident angle and a second average reflectance R45 in the visible at a substantially 45 degree incident angle. The ratio Ro/R45 is at least about 1.5. The optical construction also includes a light absorbing layer that absorbs light that is not reflected by the specular reflector.

  • Patent number: 8077395
    Abstract: An optical sheet is disposed on an observer side relative to an image source and includes a plurality of layers that control light emitted from the image source to emit the light on the observer side. At least one of the plurality of layers is a base material layer. One layer disposed on one side of the base material layer is an optical functional sheet layer which includes prisms arranged in parallel along the sheet surface of the optical sheet whereby light can be transmitted and light-absorbing parts are arranged in parallel between the prisms whereby light can be absorbed. One layer disposed on the other side of the base material layer is an adhesive layer. An adhesive layer is not provided on a side surface of the optical functional sheet layer facing the side disposed with the base material layer.

  • Patent number: 7990614
    Abstract: A projection screen is adapted to reflect the projection light generated by a projector. The projection screen includes a light absorbing layer, a light reflection layer connected adjacently to the light absorbing layer, and a light transparent layer. The light transparent layer is disposed on the light absorbing layer and the light reflection layer, and has a total reflection surface, a light emitting surface, and a light incident surface connected adjacently to the total reflection surface. The light incident surface provides a theoretical light convergence point, and the light convergence point and the location of the light reflection layer are in mirror symmetry relative to the total refection surface. The projection light enters into the light transparent layer through the light incident surface for refraction, and travels to the total reflection surface for totally reflection, and then to the light reflection layer for reflecting to the light emitting surface.
