HP develops next-gen 3D mobile display, no glasses required 

HP has developed a 3D screen for mobile devices that requires no glasses, and will be revealed in the Scientific Journal Nature on March 28. 3D hasn’t caught on like electronic manufacturers would have hoped for, a big problem being that many users experience headaches.

Here is how this new screen from HP works: with traditional 3D mobile displays, the user has to be directly in front and center in order to see the effect. However, HP has created a way where you can still see a 3D effect with the display and user at as much as a 45 degree viewing angle.

To pull this new display off, HP is using nanotechnology which involves multiple circles with tiny grooves etched into the glass, allowing for up to 64 different points of view. The grooves bend light and allow the user to see two points at one time, one with each eye, creating the no-glasses 3D effect. There are no details on when this display will make its way to phones or tablets, but HP may finally have a nice 3D solution for future mobile devices.
