  • Publication number: 20170299868
    Abstract: A spectacle lens for a display device can be fitted on the head of a user and generate an image. The spectacle lens includes a coupling-in section, a coupling-out section, and a light guiding channel. The spectacle lens includes a first partial spectacle lens connected to a second partial spectacle lens. The light guiding channel runs in the first partial spectacle lens and the two partial spectacle lenses are connected to each other via contact surfaces which extend on the one hand from the front side to the rear side and on the other hand from the edge of the spectacle lens along a predetermined length in a second direction, which runs transversely with respect to the first direction.

  • Publication number: 20170192237
    Abstract: A spectacle lens for a display device can be fitted on the head of a user and generate an image. The front side and/or the rear side can be curved. A light guiding channel can guide-light bundles of pixels of the generated image, which are coupled into the spectacle lens via the coupling-in section and coupled out of the spectacle lens via the coupling-out section. The light guiding channel includes a first reflecting surface and a second reflecting surface spaced apart from the first reflecting surface, each of which extend in a direction from the coupling-in section to the coupling-out section. At least one of the two reflecting surfaces can be formed as a switchable layer which can be switched into a first and a second state. The reflectivity of the switchable layer in the first state is higher than in the second state.

  • Publication number: 20170045743
    Abstract: A spectacle lens for a display device can be fitted on the head of a user and generate an image. The spectacle lens includes a curved front and/or side, wherein a light guiding channel which is suitable for guiding light bundles of pixels of the generated image, which are coupled into the spectacle lens via the coupling-in section of the spectacle lens, in the spectacle lens to the coupling-out section to couple them out of the spectacle lens via the coupling-out section. The coupling-out section includes at least two deflecting surfaces arranged next to each other which reflect the light bundles in the direction of the rear side for the coupling out. Deflecting surfaces can be formed as a switchable layer which can be switched into a first and a second state, wherein the reflectivity of the switchable layers in the first state is higher than in the second state.

  • Publication number: 20160282621
    Abstract: A spectacle lens for a display device may include a front side, a rear side, a coupling-in section and a coupling-out section. The coupling-out section includes at least two reflective deflecting surfaces arranged next to each other. The spectacle lens guides light bundles of pixels of the generated image to the coupling-out section in the spectacle lens and couples them out of the spectacle lens through the rear side. The spectacle lens includes a main part with the front and rear side, in which a recess extending from the rear side or from the front side to the surface structure is present, into which an insert element is inserted, the first end of which facing the surface structure is formed complementary to the surface structure, wherein the reflective deflecting surfaces lie between the surface structure of the main part and the first end of the insert element.
