  • Patent number: 10866480
    Abstract: A privacy glazing structure may be fabricated from multiple panes of transparent material that hold an optically active material and also define a between-pane space that is separated from a surrounding environment for thermal insulating properties. The privacy glazing structure may include various functional coatings and intermediate films to enhance the performance and/or life span of the structure. For example, the privacy glazing structure may include a low emissivity coating and a laminate layer positioned between an optically active layer and an exterior environment exposed to sunlight. The low emissivity coating and laminate layer may work in combination to effectively protect the optically active layer from sunlight degradation. Additionally or alternatively, the laminate layer may impart safety and impact resistance properties to the structure.

  • Patent number: 10866420
    Abstract: Embodiments include a head-worn display including a display panel sized and positioned to produce a field of view to present digital content to an eye of a user, and a processor adapted to present the digital content to the display panel such that the digital content is only presented in a portion of the field of view, the portion being in the middle of the field of view such that horizontally opposing edges of the field of view are blank areas. The processor is adapted to shift the digital content into one of the blank areas to adjust the convergence distance of the digital content and thereby change the perceived distance from the user to the digital content.

  • Patent number: 10838213
    Abstract: A display device includes a light source, a first optical system, a first mirror, a changing element, and a second optical system. The light source emits a light beam. The first optical system converts the light beam emitted from the light source into a collimated light beam. The first mirror reflects the light beam coming through the first optical system while rotating around a first axis. The changing element changes a traveling direction of the light beam reflected by the first mirror. The second optical system deflects the light beam coming through the changing element. The changing element changes the traveling direction of the light beam such that an angle of the light beam in the traveling direction which has been reflected by the first mirror is changed more greatly in a peripheral section than in a central section.
