Patent Application 20180255278 submitted by Microsoft, published in 2018-09-06 named "MEMS scanning display device" breaks down the concept and method to design a 1440p capable two-mirror Laser Beam Scanning (LBS) MEMS design.
On April 26, 2018 a company called Microvision announced that they were sampling their next gen two-mirror LBS MEMS Scanner capable of 1440p and 120hz.
Microsoft has published multiple patents that reference designs utilizing this technology that isn't that new, but has never been implemented in a NED since the days of the NOMAD retina display system for the Department of Defense.
Some other notable patents which reference LBS MEMS which describe wide field of views, foveated rendering, and eye tracking through this system can be found below.
* USPTO Applicaton #: 20180176551 - Devices and methods for providing foveated scanning laser image projection with depth mapping
* Patent #: 15467855 - Laser scan beam foveated display
* USPTO Applicaton #: 20180295331 - FOVEATED MEMS SCANNING DISPLAY
* USPTO Applicaton #: 20180314325 - EYE TRACKING USING SCANNED BEAM AND MULTIPLE DETECTORS
Ther's been over 20 patents connecting the technology together. I can't wait to see what Microsoft has come up with.
All patent sources come from the diligent researchers on the "MVIS/MSFT timeline" thread on reddit.
