Researchers in Chengdu, China have figured out how to construct high-quality glasses-free 3D displays. Glasses-free 3Ds usually comes with a whole array of drawbacks, but the use of spherical lenses in the display helps get around some of these flaws.
The screen does away with the use of glasses to split up images to create a 3D effect -- you can simply look at the screen and enjoy a 3D effect. This is possible thanks to the principle of parallax, wherein each eye sees a different image beamed from the screen using a parallax barrier. The disadvantage of this technology is that the screens only work within a narrow viewing angle of 20 to 30 degrees.
The current proof-of-concept glasses-free 3D display works within a range of 32 degrees. However, this technology is still highly encouraging and it will be interesting to see if it becomes commercially viable in the coming years.
