A '''3D display''' is a type of [[visual display]] that allows viewers to perceive depth in the generated imagery. It does so using [[depth cue]]s based largely on focus and [[stereopsis]].

+3D displays can be world-fixed, like mounted on a desk, or they can be head fixed, like built into a VR headset.
To get a 3D display to show proper [[accommodation]] cues AKA focus, there are multiple ways. The two main ways are [[holographic display]]s and [[light field display]]s. A holographic display uses interference patterns to construct light as wave-like movements in an electric field that reach the eye. A light field display sends focal stacks of images based on [[ray]]s to the eye.
