  • Patent number: 9915812
    Abstract: A compact display module, such as can be used in wearable computing headset applications, includes a microdisplay with a display surface that is virtually imaged by a lens. The lens is positioned to receive light from the display surface of the microdisplay. The lens defines an angled fold, whereby light from a display generated at the display surface is reflected within the lens to thereby form a virtual image of the display in a virtual image plane that is angled non-perpendicularly relative to the display surface of the microdisplay.
    Type: Grant

  • Patent number: 7365811
    Abstract: Alignment of an imaging area of a display with a user's eye provides optimum image quality for the user. Typically, a display is formed of a display panel encased within a carrier. The carrier is used to mechanically align the display panel within a device housing. However, the display panel must first be aligned within the carrier and the carrier and display combination aligned within a device housing. By utilizing the display panel without the carrier, one alignment step is removed from the installation process. Placing the display panel within a housing having an alignment device ensures proper alignment of an imaging area of the display panel with an opening of the housing.

  • Publication number: 20040113867
    Abstract: Various embodiments of a head-mountable display system can be adapted to allow users to see through or above or below the display assembly. Such range of vision can be achieved by positioning the display assembly into display pods housed in clear plastic; forming the frame into an “S”-shape positioned on the bridge of the nose so as to allow the user to see over it; positioning retractable display pods into a hard support frame, or other means. Various parts of the head-mountable display system, such as temple arms, ear phones, display assembly, and the head band, can be modified so as to achieve ergonomically optimal solution.
