The key component of an LFD is a dense "field" of light rays generated by a projector array system or a high resolution LCD panel with optics. The end product is a full-color, naturally observable 3D video display that runs in real time and doesn't require glasses.

In order to operate, Light Field Displays (LFDs) slice up the image volume radially, much like a cake. Volumetric displays, on the other hand, slice the volume like a loaf of bread. The typical angular separation between slices in an LFD is about one degree. At standard viewing distances (>1.0 m/3 ft), so that at least two of these slices are seen by each pupil in your eye. As a result, as the viewer navigates the scene within the display's field of view (FoV), adjacent views seamlessly merge together. Usually, the FoV is at least fifty degrees.
