There are many types of 3D displays: stereoscopic 3D displays show a different image to each eye; autostereoscopic 3D displays do this without the need for any special glasses or other head gear; holographic 3D displays reproduce a light field which is identical to that which emanated from the original scene. In addition there are volumetric displays, where some physical mechanism is used to display points of light within a volume. Such displays use voxels instead of pixels. Volumetric displays include multiplanar displays, which have multiple display planes stacked up; and rotating panel displays, where a rotating panel sweeps out a volume. Stereo card image modified for crossed eye viewing. ... Autostereoscopy is a method of displaying three-dimensional images that can be viewed without the use of special headgear or glasses on the part of the user. ... Holography (from the Greek, όλος-hòlòs whole + γραφή-grafè writh) is the science of producing holograms; it is an advanced form of photography that allows an image to be recorded in three dimensions. ... A volumetric display device is a graphical display device that forms a visual representation of an object in three physical dimensions, as opposed to the planar image of traditional screens that simulate depth through a number of different visual effects. ... A voxel (a portmanteau of the words volumetric and pixel) is a volume element, representing a value on a regular grid in three dimensional space. ... This example shows an image with a portion greatly enlarged, in which the individual pixels are rendered as little squares and can easily be seen. ...


A wide range of organisations have developed 3D displays, ranging from experimental displays in university departments to commercially available displays. Companies involved include Holografika, NewSight, Pavonine, Philips and Spatial View; or not available at the moment ones like Sharp or SeeReal Technologies. Philips HQ in Amsterdam Koninklijke Philips Electronics N.V.

Holographic displays display a light field which is identical to that which emanated from the original scene, giving a perfect three-dimensional image, although usually only at the particular wavelengths of the lasers used to record the image.
Rotating Panel Displays There is a new type of 3D display that is a cross between stereoscopic and holographic.
As the display panel spins at a very high rate of speed, at each step of the stepper-motor the screen is updated for that "Slice" of what the image is at that point.

Autostereoscopic viewing is the ability for the displayed objects to be continuously viewable from all regions within the viewing zone, and accommodation is the ability for the user to focus on selected depth planes within the object.
Display approaches in which two-dimensional reflective or emissive surfaces are swept throughout a third dimension have been demonstrated, but they too have restricted viewing zones and require large surfaces to be deflected or rotated at high speeds.
Scanning the pump laser beams inside the display at a sufficiently high rate decreases the excitation period, and reduces single frequency upconversion in erbium to a magnitude where it is not noticeable to the viewer.
