Head mounted display having alignment maintained via structural frame
First Claim
1. A head mounted display device comprising:
- a structural frame arranged generally along a first axis and a second axis for viewing along a third axis, the first, second, and third axes being mutually perpendicular, the structural frame including opposing upper and lower rims between which are defined left and right openings;
left and right micro-displays coupled to the structural frame, and configured to project visual content in a substantially forward direction along the third axis toward the left and right openings, respectively, and away from a user;
left and right optical elements coupled to the structural frame and respectively positioned over the left and right openings and each including an at least partially reflective surface facing in a substantially rearward direction along the third axis; and
wherein the structural frame maintains the optical elements in alignment to define an optical light path for reflectively guiding a light ray bundle from the micro-displays to a user'"'"'s eyes,wherein the structural frame includes left and right pockets each extending downward from the upper rim along the second axis toward the lower rim and respectively containing the left and right micro-displays,wherein each of the optical elements includes a first mirror and a third mirror with reflective optical surfaces facing in a substantially rearward direction along the third axis and further comprising left and right second mirrors coupled to the structural frame with reflective optical surfaces facing in a substantially forward direction along the third axis.

Abstract
A head mounted display device includes a structural frame arranged generally along a first axis and a second axis for viewing along a third axis, the first, second, and third axes being mutually perpendicular. The structural frame includes opposing upper and lower rims between which are defined left and right openings. Left and right micro-displays are coupled to the structural frame, and are configured to project visual content in a substantially forward direction along the third axis toward the left and right openings, respectively, and away from a user. Left and right optical elements are coupled to the structural frame and respectively positioned over the left and right openings and each include an at least partially reflective surface facing in a substantially rearward direction along the third axis. The structural frame maintains the optical elements in alignment to define an optical light path for reflectively guiding a light ray bundle from the micro-displays to a user'"'"'s eyes.
