The EPE improves the optical performance of the display system. The EPE could include a diffusive optical element, diffractive optical element, micro-lens array (MLA), or relay of aspherical lenses. A dual MLA EPE may have cells that prevent cross-talk between adjacent pixels. A dual MLA EPE may have a non-periodic lens array. The optical power of one MLA may be different from the other MLA.Wall; Richard Andrew (Kirkland, WA), Vallius; Tuomas (Espoo, FI), Juhola; Mikko (Muurla, FI)http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=10,025,093.PN.&OS=PN/10,025,093&RS=PN/10,025,093

The light source driver selectively drives one or more light emitting elements of a light source to thereby produce a light beam that is directed towards a same MEMS mirror. The controller controls rotation of the MEMS mirror(s) in a fast-axis direction and a slow-axis direction in order to raster scan an image using the light beam reflected from the MEMS mirror(s). In order to achieve a first line density in a first portion of the image being raster scanned and to achieve a second line density, that is less than the first line density, in a second portion of the image being raster scanned, the controller dynamically adjusts a speed at which one of the MEMS mirror(s) is rotated in the slow-axis direction.

Massachusetts Institute of Technology (Cambridge, MA) 9,927,616March 27, 2018August 16, 2016Methods and apparatus for transparent display using scattering nanoparticlesTransparent displays enable many useful applications, including heads-up displays for cars and aircraft as well as displays on eyeglasses and glass windows. Unfortunately, transparent displays made of organic light-emitting diodes are typically expensive and opaque. Heads-up displays often require fixed light sources and have limited viewing angles. And transparent displays that use frequency conversion are typically energy inefficient. Conversely, the present transparent displays operate by scattering visible light from resonant nanoparticles with narrowband scattering cross sections and small absorption cross sections. More specifically, projecting an image onto a transparent screen doped with nanoparticles that selectively scatter light at the image wavelength(s) yields an image on the screen visible to an observer. Because the nanoparticles scatter light at only certain wavelengths, the screen is practically transparent under ambient light. Exemplary transparent scattering displays can be simple, inexpensive, scalable to large sizes, viewable over wide angular ranges, energy efficient, and transparent simultaneously.Hsu; Chia Wei (Cambridge, MA), Qiu; Wenjun (Chicago, IL), Zhen; Bo (Cambridge, MA), Shapira; Ofer (Cambridge, MA), Soljacic; Marin (Belmont, MA)http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=24&f=G&l=50&co1=AND&d=PTXT&s1=MEMS&s2=Microvision&OS=MEMS+AND+Microvision&RS=MEMS+AND+Microvision
