A '''3D display''' is a display gadget that can show solid-looking objects. It does this by using focal cues. Solidity can be generated using [[holographic display]]s and [[light field display]]s. 3D displays work by showing different focal depths at the same time. The term can also refer to a [[multiple viewpoint display]].

A '''3D display''' is a theoretical type of display that can show a completely natural 3D scene. It does this by using focal cues. Solidity can be generated using [[holographic display]]s and [[light field display]]s. 3D displays work by showing different focal depths at the same time. The term can also refer to a [[multiple viewpoint display]].

3D displays connected to a computer system can enable a 3D human-computer interaction loop, which can be used in 3D software for design. A 3D display shows [[depth cue]]s based largely on focus and/or [[binocular disparity]].
