3D Display
A 3D display is any display capable of conveying three-dimensional images to the user.
There are two categories of 3D displays: stereoscopic 3D diplays and real 3D displays. Stereoscopic displays use various methods to convey different images to each of the eyes, causing the perception of depth. Real 3D displays use holograms in true space. 3D displays may use voxels instead of pixels.
