What is Looking Glass Hololuminescent Display?

A Looking Glass hololuminescent display is a glasses-free 3D display that presents a light field, an array of many slightly different images projected simultaneously through a lenticular lens structure, so a viewer's eyes each receive a distinct perspective of the same scene and perceive it as a volumetric image with depth. Unlike stereoscopic 3D, which relies on special glasses splitting one pair of images, this light-field approach lets multiple viewers see correct parallax from different positions around the screen without eyewear.
