PolarScreens is developing a new 3D display technology capable of displaying full HD resolution in each eye without
the need for glasses. The technology combines a regular backlight, a 120Hz 3D LCD panel, a vertical Patterned active
shutter panel and a head tracking system. The technology relies on a 12-sub-pixel wide alternated pattern encoded in
the stereo image to follow the head movement. Alternatively for a passive 3D display, the barrier is made of vertical
strip Polarizer Film. This can be applied to any full resolution polarized display like iZ3D, Perceiva, or active retarder
The end result is a full resolution autostereoscopic display with complete head movement freedom. There are no
mechanical moving part (like lenticular) or extra active components to steer the correct L/R image to the user's eyes.
The new display has the capacity of displaying 2D/3D information on a pixel per pixel base so there is no need for full
screen or windowed 2D/3D switchable apparatus.
PolarScreens, with the collaboration of MacNaughton Inc., has developed a stereoscopic display that has the unique advantage of displaying two images without multiplexing whatsoever. Multiplexing means timesharing or pixel sharing between the left and right eyes. This effectively reduces resolution or brightness, and is subject to crosstalk. PolarScreens uses 2 LCD panels stacked on one another to avoid this.
Instead of using an LCD to block a specific eye, PolarScreens uses the second LCD to add extra information to the photon using a polar coordinate transformation algorithm. The first LCD controls total pixel intensity and the second controls left-eye/right-eye distribution ratio. This is the only technology where one photon carries the information for both eyes.
The theoretical concept was proven in 1996. At the time many technologies needed were inadequate for a commercial product; LCDs were slow, had very small aperture and were very expensive. Electronics were too slow for real time transformation. Micro-optical technologies were at its beginning. The project was periodically re-activated in order to re-evaluate its feasibility. In 2002 it was determined that these technologies were mature enough to re-activate the project. Since then PolarScreens has worked on improving the technology and built many prototypes of different size ranging from 15in to 19in. As a result, today it is possible to manufacture a very high quality stereoscopic monitor based on PolarScreens technology at a reasonable price.
