  • Patent number: 6618099
    Abstract: A compact, head-mountable display device for transmitting an image to a user's eye is provided. The display device includes a support fixture comprising an elongated member configured to allow passage of ambient light across a direction of elongation of the elongated member to a user's eye. A display, such as an LCD, is supported by the support and is operative to provide an image. An eyepiece assembly is supported by the support fixture in proximity to the display to receive the image from the display and to direct the image to the user's eye. The support fixture also defines an illumination path along the elongated member, and the display is located to receive illumination light on the illumination path from a light source.
