HP Labs 3D multi-directional backlight technology

HP Labs’ display technology forms 3D images by projecting different 2D images into different regions of space. A viewer located near the display will see a different image from his right and left eye, resulting in a 3D effect without the need for special glasses or eye tracking. As the viewer moves around (or tilts) the display, he or she will perceive a succession of different image stereo pairs, creating the illusion of continuous motion parallax.
