Editing 3D display (section)

====Head-mounted projection displays====
Head-mounted projection displays (HMPD) is similar to head-mounted displays but with images projected to and displayed on a [[Retroreflective sheeting|retroreflective screen]], The advantage of this technology over head-mounted display is that the [[Accommodation (eye)|focusing]] and [[vergence]] issues didn't require fixing with corrective eye lenses. For image generation, [[pico projector|pico-projectors]] are used instead of [[LCD]] or [[Organic light-emitting diode|OLED]] screens.<ref>{{cite journal|title=A mobile head-worn projection display. | pmid=19550732 | volume=15 | issue=22 | journal=Opt Express | pages=14530–8 | last1 = Martins | first1 = R | last2 = Shaoulov | first2 = V | last3 = Ha | first3 = Y | last4 = Rolland | first4 = J | doi=10.1364/oe.15.014530| year=2007 | bibcode=2007OExpr..1514530M | url=https://stars.library.ucf.edu/cgi/viewcontent.cgi?article=8407&context=facultybib2000 | doi-access=free }}</ref><ref>{{cite journal|title=Investigation of a 3D head-mounted projection display using retro-reflective screen. | pmid=25089403 | volume=22 | issue=15 | journal=Opt Express | pages=17823–9 | last1 = Héricz | first1 = D | last2 = Sarkadi | first2 = T | last3 = Lucza | first3 = V | last4 = Kovács | first4 = V | last5 = Koppa | first5 = P | doi=10.1364/oe.22.017823| year=2014 | bibcode=2014OExpr..2217823H | doi-access = free }}</ref>
