It came with a bang and went without no one noticing.Yes some might ask :have you gone mad? No guys Iam talking about the phones that had 3D screens,the HTC EVO 3D and the LG Optimus 3D.Well if you did it's a good time to regain your memory.Well that phones had many drawbacks as many felt headache using the device because you have to stare at the screen directly.This problem went to the decline of these devices.An unworthy ending to an artistic piece of technology.
Any ways HP claims that they have solved these problems and their new discovery allows the user to be positioned at as much as a 45 degree angle in any direction to the screen and still see the images in 3D. HP scientists used nanotechnology to etch into the glass, multiple circles with tiny grooves. The grooves bend light into 64 points of view. As a user views the screen and moves it, he will see two of these points at one time, one with the left eye and one with the right, creating the 3D effect.The article's lead author, David Fattal, compared the effect to the hologram of Princess Leia from the classic Star Wars. Fattal said that the image won't pop out as much as Princess Leia's did in the movie.Source
