  • Layered structure with embedded graphical pattern
    Patent number: 11001095
    Abstract: A method is presented for producing an optically transmissive layered structure for use as a display protector for electronic devices. The method comprises printing an ink pattern on a base layer, where said base layer is substantially optically transparent, and the base layer and ink are configured so that the ink reflects light with high incidence angle and transmits light with low incidence angle, when in use, thus displaying the pattern in the absence of light with high intensity and low incidence angle, the pattern becoming substantially undetectable otherwise.
    Type: Grant
    Filed: September 25, 2017
    Date of Patent: May 11, 2021
    Assignee: DOCOVER OY
    Inventors: Teppo Hyvönen, Jari Ronkainen, Atso Toimela, Pusheng Peng
