  • Patent number: 10139639
    Abstract: The present disclosure provides a display panel and a display device. The display panel includes a curved substrate having a first curvature and a curved grating layer corresponding to the curved substrate and having a second curvature, wherein, light that is emitted into the display panel is converged by means of the curved substrate having the first curvature and the curved grating layer corresponding to the substrate and having the second curvature, so as to reduce crosstalk between view images. Further, focusing effect of the view images viewed can be improved such that stereoscopic effect of the view image viewed is much more excellent as the distance between each point of the curved substrate and each point of the curved grating layer along the viewing direction is equal to the focal length for the grating structure.

  • Patent number: 8448991
    Abstract: Improvements that prevent tampering of images on identification documents for example identity cards, credit cards and the like, and passports. The document includes a full color image of a person, and a second, full, achromatic image of the person formed underneath and spaced from the color image and in congruence therewith using a laser. The second full image is not visible underneath the first full image during normal viewing of the document, and is only visible upon removal of all or a portion of the first full image. As a result, the document and the image have no outwardly apparent visual difference to the document holder or to a would-be counterfeiter. This provides a covert security feature that is not known or seen until the document is attacked by removing the first full image.

    Abstract: Into a plastic card (1) of polycarbonate layers (10; 11; 12) there is laminated a security thread (3) by applying pressure and temperature, the security thread itself having a carrier foil (5) of polycarbonate and a coating (6) that is borne by the carrier foil and conveys holographic information. The connection of the polycarbonate carrier foil (5) of the security thread with the polycarbonate layer (10; 11; 12) of the data carrier adjoining said carrier foil takes place without using an adhesive or primer.

  • Patent number: 8356841
    Abstract: The invention relates to a customized multi-layer support which takes the general form of a card, such as an identification card. The support includes a card body, the upper face of which is provided with externally-visible personal information; and a film which is at least partially transparent and which is fixed to the upper face of the card body. The support has boundary lines which define the areas of the aforementioned film with reduced or increased mechanical strength. The invention also relates to a method of producing one such customized support.

  • Patent number: 8322752
    Abstract: There is provided a laser-marking multilayer sheet for an electronic passport formed by laminating five sheets of a multilayer sheet A/a multilayer sheet B/a film C/a multilayer sheet B/a multilayer sheet A. The multilayer sheet B is a colored laser-marking multilayer sheet. The film C is a laser-marking multilayer sheet made of a film for the electronic passport. The laser-marking multilayer sheet can have clear letters, symbols, and images, which are excellent in a laser-marking property and high in contrasts between the original surface color and the printed portions. The laser-marking multilayer sheet is excellent especially for inhibiting the falsification and forgery thereof.

  • Patent number: 8308197
    Abstract: Described is a security element for increasing the forgery-proof nature of a security document, in particular an identity card or pass, a passport or an identification card. The security element (1) has a first diffractive region (15) having an open code which is visible with a naked eye. The first diffractive region further has a concealed code which is not visible with the naked eye and which can be reconstructed from the arrangement of diffractive microregions disposed in the first region (1) and/or from the structure of the first diffractive region (1). Further described is a method of increasing the forgery-proof nature of a security document.

  • Patent number: 8298753
    Abstract: The invention relates to a method of generating a laser marking in a security document by means of at least one laser beam, the security document having at least one laser-markable layer and also at least one reflecting layer which overlaps at least partly with the at least one laser-markable layer and has opaque regions. The at least one reflecting layer has at least one transparent region and, at least visually, is not significantly altered by the laser treatment of the laser-markable layer.

  • Patent number: 8289595
    Abstract: The invention relates to a security-conscious hologram which can apply a sufficient three-dimensional appearance to a reconstructed image in both its vertical and horizontal directions, and which is difficult to illegally copy and easily told from any illegal copy forged from it, and a holographic process of recording it The hologram H2 is of a combined reflection and volume type, wherein a subject image P is recorded, and minute reflection images F and O? from a light source are recorded at least in front of, or in the rear of, the subject image P, both in a reconstructible fashion, and a viewing position E is moved along a hologram surface, so that the subject image P and the minute reflection images F and O? are viewable at varied relative positions.

  • Patent number: 8246081
    Abstract: A security marking system for producing a secure marking label includes a support sheet, such as a silicon-containing sheet, having two separate flaps on a first folding line, the first flap supporting, on the recto side, a first holographic component whereof the surface contacting the support sheet is coated with an adhesive film. The second flap supports, on the same recto side, a second component formed by a film whereof the surface contacting the support sheet is coated with an adhesive film and the opposite surface bears personalizing indicia. The first flap includes a second folding line that is substantially parallel to the first folding line.

  • Patent number: RE44890
    Abstract: An authenticity indicator is difficult to be forged and has an authenticity that can be confirmed easily and accurately. The authenticity of the authenticity indicator can be checked by making light enter the authenticity indicator from front side and observing the light emerging from the front side or rear side. The authenticity indicator includes a polarized-light selectively reflecting layer that reflects a specified polarized component of incident light, and a transmission volume hologram layer disposed on the front side of the polarized-light selectively reflecting layer. According to this authenticity indicator, its authenticity can be checked accurately by making use of its first authenticity recognition function attributed to the diffracting action of the transmission volume hologram layer and its second authenticity recognition function attributed to the polarized-light selectivity of the polarized-light selectively reflecting layer.
