A holographic screen is a display technique that uses glass substrates coated with the projection surface of a video projector. "Holography" means that the coating light beams formed using microlenses. Design and lens characteristics correspond to the holographic area. The lenses may seem similar to the Fresnel lenses used in overhead projectors. The effect is that of a display space, as the image carrier appears very transparent. In addition, the beam manipulation by the lenses can be used to make the image appear to be floating in front of or behind the glass, and not directly on it. However, this display is only two-dimensional and three-dimensional, not true. It is unclear whether this technology will be able to provide acceptable images in three dimensions in the future.
