| Abstract: |
[From equivalent
EP0344881A2]
A head mounted display for presentation of video information includes a virtual raster visual display unit, an attachment means for attaching the display unit to the head of the user, a support means connected to the attachment means for supporting the display unit within the user's field of vision, and a remote signal means for providing power, timing, control signals and display information to the display system. The head attachment means can be symetrically designed to allow positioning of the display unit in front of either of the viewer's eyes, or the attachment means may be eliminated completely and the support means and display unit attach directly to a conventional helmet or the user's eye glasses.

1. A head-mounted visual display system comprising: a number of independently illuminable light-emitting elements (50);
imaging optics (90,100) for creating an enlarged virtual image of said light-emitting elements (50);
a mirror (70) in which the reflection of said enlarged virtual image can be observed;
means for repetitively moving said mirror through a predetermined range of movement to create a two-dimensional raster image of said reflection, said raster image being comprised of a number of picture elements, said number of picture elements being greater than the number of said light-emitting elements;
means (45) for selectively illuminating said light-emitting elements;
attachment means (22A,24A,26A) to be worn on the head of a user;
support means (10A,12A,20A) connected to said attachment means (22A,24A,26A) and said display system (40) for supporting said display system (40) within said users field of vision;
signal means (34) located remotely from the display system (40) and electrically or optically connected (32) to said display system (40) for providing power, data, timing and control signals necessary to drive said display system (40),
said support means (10A,12A,20A) including a light-tight box (10A) connected integrally with the support means (10A,12A,20A) for housing said light-emitting elements (50), said imaging optics (90,100) and the mirror (70) of said display system (40).
