Head Mounted Display With Micro-Display Alignment Mechanism
First Claim
1. A head mounted display device comprising:
- a structural frame arranged generally along a X-axis and a Y-axis for viewing along a Z-axis, the X, Y, and Z axes being mutually perpendicular;
a micro-display coupled to the structural frame, and configured to project visual content in a substantially forward direction along the Z-axis away from a user;
a group of one or more optical elements with reflective optical surfaces coupled to the structural frame and respectively positioned on a front side of the micro-display to reflectively guide a light ray bundle from the micro-display to a user'"'"'s eye; and
a micro-display alignment mechanism mounted to the structural frame and configured to align and control the reflectively guided light ray bundle from the micro-display to the user'"'"'s eye by positioning the micro-display along the X and Z axes.

Abstract
A head mounted display device includes a structural frame arranged generally along a X-axis and a Y-axis for viewing along a Z-axis, the X, Y, and Z axes being mutually perpendicular. A micro-display is coupled to the structural frame, and configured to project visual content in a substantially forward direction along the Z-axis away from a user. A group of one or more optical elements with reflective optical surfaces is coupled to the structural frame and respectively positioned on a front side of the micro-display to reflectively guide a light ray bundle from the micro-display to a user'"'"'s eye. A micro-display alignment mechanism is mounted to the structural frame and configured to align and control the reflectively guided light ray bundle from the micro-display to the user'"'"'s eye by positioning the micro-display along the X and Z axes.

16. A micro-display alignment mechanism configured to be mounted to a structural frame of a head mounted display device, the structural frame arranged generally along a X-axis and a Y-axis for viewing along a Z-axis, the X, Y, and Z axes being mutually perpendicular, the micro-display alignment mechanism comprising:
-
a micro-display holder configured to hold a micro-display; and a carriage configured to couple to and constrain motion of the micro-display holder to motion along the X and Z axes and restraining rotational motion of the micro-display holder to align and control a reflectively guided light ray bundle from the micro-display to a user'"'"'s eye by positioning the micro-display along the X and Z axes. - View Dependent Claims (17, 18, 19, 20)

21. A method of assembling a micro-display mechanism configured to be mounted to a structural frame of a head mounted display device, the structural frame arranged generally along a X-axis and a Y-axis for viewing along a Z-axis, the X, Y, and Z axes being mutually perpendicular, the method comprising:
-
attaching a micro-display to a first portion of a micro-display holder; assembling a second portion of the micro-display holder to a carriage configured to couple to and constrain motion of the micro-display holder to motion along the X and Z axes and restraining rotational motion of the micro-display holder to align and control a reflectively guided light ray bundle from the micro-display to a user'"'"'s eye by positioning the micro-display along the X and Z axes; providing a X-gear including a user-manipulation portion attached to a shaft; inserting the X-gear shaft into a first opening in the carriage; providing a Z-gear including a user-manipulation portion attached to a shaft; and inserting the Z-gear shaft into a second opening in the carriage.
