A holographic display is a type of 3D display that utilizes light diffraction to reconstruct a 3D wavefront of an object or a scene and therefore display a three-dimensional image to the viewer. Holographic displays are distinguished from other forms of 3D displays in that they do not require the viewer to wear any special glasses or use external equipment to be able to see the image, and do not cause a vergence-accommodation conflict.
