laser plasma displays, developed in 2005 by the university of texas, utilize a series of powerful lasers that focus light in desired positions in order to create plasma excitations with the oxygen and nitrogen molecules in the air. this type of holographic display is capable of producing images in thin air, without the need for any sort of screen or external refraction media. the laser plasma display is able to depict very bright and visible objects, but it lacks in terms of resolution and picture quality.
