Patents by Inventor Kari Juhani Rinko

Kari Juhani Rinko has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10884260
    Abstract: Three-dimensional display systems may include polarized displays that polarize light emitted from a first set of areas of the display with a first polarization for a first eye of the viewer and that polarizes light emitted from a second set of areas of the display with a second polarization for a second eye of the viewer. This may result in dark areas being perceived by a viewer when viewed through polarized 3D glasses. Systems and technologies according to this disclosure may include 3D glasses that have a lenses configured to redirect a portion of incoming light in a first axis to at least partially illuminate the dark areas.

  • Patent number: 10422938
    Abstract: An ultra thin lighting element including at least one light source (1b). A lightguide element (2c) includes one lightguide layer comprising a plurality of discrete fine optic surface relief structures (3e) on at least one portion of at least one surface. Each surface relief structure (3e) includes basic structural features on the order of about 10 microns or less in height, and on the order of about 10 microns or less in each lateral dimension. The number, arrangement and size of each surface relief structure (3e) and height and lateral dimensions of the structural features of the surface relief structures (3e) being varied to provide a desired degree of outcoupling modulation of light incoupled into the light guide element.

  • Patent number: 10365471
    Abstract: A display device includes a bottom support plate and an opposing top support plate. A pixel region is positioned between the bottom support plate and the top support plate. The pixel region includes a plurality of sub-pixels. A color filter layer is positioned within the pixel region. The color filter layer includes a plurality of color filters, wherein each color filter is positioned within a respective sub-pixel. A diffusion layer is positioned on a first surface of the top support plate between the top support plate and the color filter layer.

  • Publication number: 20180088270
    Abstract: A display device using specular reflection, such as an electrowetting display, includes a lightguide having internal optics that direct light propagating through the lightguide onto a reflective surface of the display device so that the light is reflected at an angle that improves the illumination and/or contrast ratio of an image displayed to a viewer. Various cavity shapes for the internal optics provide different manufacturing and operation efficiencies.

  • Patent number: 9684338
    Abstract: A multifunctional device layer may include a lightguide substrate having an optically patterned surface and an opposing non-patterned surface. The non-patterned surface of the lightguide substrate is coated with a first material having a first refractive index and the patterned surface is coated with a second material having a second refractive index. The first refractive index may be lower than the second refractive index and each may be lower than a refractive index of the lightguide substrate. A touch sensor may be formed on the coated non-patterned surface of the lightguide substrate, the coated patterned surface, or on an interstitial layer deposited on the coated non-patterned surface or the coated patterned surface. An anti-glare/anti-reflective coating potentially having ultraviolet (UV) absorption properties may be applied to the touch sensor.

  • Publication number: 20140192006
    Abstract: Various approaches discussed herein provide a display screen that integrates both capacitive touch sensing and a light guide onto a single optically clear substrate. The substrate can be integrated into a portable device, such as an electronic reader (e-reader) device having a reflective display in order to both illuminate content displayed on the e-reader device and to provide touch sensing input to the device. The capacitive sensors can be fabricated on one side of the optically clear substrate, while the light guide can be fabricated on the opposite side of the substrate.
