HP Labs unveiled a new 3D display technology for mobile devices.
HP Labs developed a new 3D display technology ideal for mobile phones, watches and tablets. The multi-directional diffractive backlight technology permits the rendering of high-resolution, full-parallax 3D images in a very wide view zone (up to 180 degrees in principle) at an observation distance of up to a meter.
The key to HP's design is a guided-wave illumination technique based on light-emitting diodes that produces wide-angle multiview images in color from a thin planar transparent lightguide. Pixels associated with different views or colors are spatially multiplexed and can be independently addressed and modulated at video rate using an external shutter plane.
