Light field display reproduces a 3D image visible to viewers without the need to wear glasses.

This technology uses a display and optical devices to display stereoscopic images by varying intensity and direction of light. 

Unlike conventional displays, the light field display can create natural 3D images as it demonstrates the depth and sides of the projected object depending on a viewer’s perspective. The light field display is gaining traction as one of the next-generation displays as it is open to various applications by converging with AR technology.
