Dolby is working with Philips to manufacture the displays, which use a sheet of undulated plastic to deflect pixels in various directions â€” there are 26 different viewing angles in all. Because the image is being sent in so many directions at once, the display has to be incredibly high-resolution to look good (the prototype was a quad-HD TV), which is why Dolby reps said the same impressive viewing angles are going to be harder to achieve on smaller devices like smartphones. The companies are waiting for the higher-res displays to be more mainstream, and less expensive.
Higher resolution LCD TVs are coming and their prices will fall; it’s a matter of when not if. 3D should move away from having to wear glasses, permanently.
