  • Patent number: 10310268
    Abstract: An apparatus, for use in replicating an image associated with an input-pupil to an output-pupil, comprises an optical waveguide including a bulk-substrate, an input-coupler and an output-coupler. The bulk-substrate includes first and second major sides and peripheral sides. The input-coupler couples, into the waveguide, light corresponding to the image associated with the input-pupil. The output-coupler couples, out of the waveguide, light corresponding to the image that has traveled through the waveguide from the input-coupler to the output-coupler at least in part by way of TIR. At least one of the peripheral sides includes first and second surfaces that define first and second planes angled 45 degrees relative to one another. Such a peripheral side provides for effective recycling of light that would otherwise leak out of the waveguide through the peripheral side.

  • Patent number: 9720239
    Abstract: A half mirror layer has an angle dependency in which when an angle of incidence becomes larger than the angle of incidence range of image light, reflectance increases, such that it is possible to prevent unintended light, which is emitted to a light transmitting member from a light guiding member and is reflected inside a light transmitting member, from being returned to a light emission portion of the light guiding member after passing through the half mirror layer as a reflective film at a relatively large angle of incidence. Therefore, it is possible to prevent the image light passed through the light transmitting member from becoming ghost light while mitigating the demand for increasing processing accuracy of the light transmitting member, and bonding accuracy between the light guiding member and the light transmitting member, to provide a high quality virtual image displayed by a virtual image display device.

A see-through compensation lens, containing multiple freeform refractive surfaces, enables proper viewing of the surrounding environment, through the combined waveguide and lens.

  • Patent number: 9291822
    Abstract: The sizes of the respective reflecting units vary in the image take-out section along the Z direction in association with the state of the total reflection angle in the light guide section. Thus, it becomes possible to keep the sufficient effective light beam width of the image light input thereto in all of the reflecting units. Therefore, the deterioration in the image light caused by the reflection in the reflecting units can be avoided, and as a result, the degradation of the resolution of the image due to the virtual image light thus emitted can be prevented.
