3D display technology refers to the use of three-dimensional visual representations in electronic devices such as televisions, computer monitors, and smartphones. This technology creates the illusion of depth perception and spatial relationships by presenting images in a way that simulates the way we see objects in the real world. 3D displays typically use techniques such as stereoscopy, autostereoscopy, holography, or volumetric displays to achieve this effect. This technology is used in various industries including entertainment, gaming, healthcare, and design to create immersive and engaging visual experiences for users.
