Viewer discomfort is one of the biggest obstacles preventing widespread application of 3D display technology – especially for portable devices whose slim design poses an extra challenge. Researchers at Sun Yan-Sen University, China have developed new display based on "super multi-view technique" which works to reduce viewer discomfort. It also greatly decreases required number of microdisplays, which makes a compact design possible. Device is described in a paper in OSA's Optics Express journal.
