Abstract: A head mounted display (HMD) system includes a light source, a scanning mirror assembly, and an output screen. The light source includes source elements that emit image light. The scanning mirror assembly scans the image light at least along one dimension to form tiled portions of scanned image light of an output image. The scanning mirror assembly directs at least one of the tiled portions of the output image to a first position, and redirects at least one of the tiled portions of the output image to a second position adjacent to the first position. The scanning mirror assembly includes scanning mirrors operating within a first range of scanning frequencies along a slow axis and a second range of scanning frequencies along a fast axis. The output screen outputs a tiled image light to an eyebox region using the scanned image light.

Claims:

1. A head mounted display (HMD) system comprising: a light source including a plurality of source elements that are configured to emit image light; a scanning mirror assembly configured to scan the image light at least along one dimension to form a plurality of tiled portions of scanned image light representing an output image, the scanning mirror assembly comprising one or more scanning mirrors operating within a first range of scanning frequencies along a slow axis and a second range of scanning frequencies along a fast axis, the scanning mirror assembly directing at least one of the plurality of tiled portions of the scanned image light to a first position, the scanning mirror assembly redirecting at least one of the plurality of tiled portions of the scanned image light to a second position next to the first position; and

Sooo I found this patent using the nifty "see-the-forest" patent website which was shared recently. I plugged the first easter egg patent in there "Phased locked resonant scanning display projection" and this along with a few Microsoft patents popped up :)

I'll probably slowly go through them and see what other stuff I can find.
