Toshiba has developed a 21-inch autostereoscopic high-definition display for use in next-generation 3D monitors that enables the user to enjoy three-dimensional images without the need for special glasses. It employs an integral imaging system (a ?light field? display) to reproduce a real object as a 3D image that can be viewed without glasses over a wide range of viewing angles. It also features a multi-parallax design that enables motion parallax, which cannot be achieved by systems using glasses. The multi-parallax approach results in images that change depending on the viewer?s position.
The display can be used in a vertical or horizontal position. When used in the vertical position, the user faces the upright screen from the front as a person would usually use a 2D monitor. However, when used in the horizontal position, the user overlooks the stereoscopic image formed by the display lying face-up, as one would overlook a relief model. Compared with the front view, the 3D images seen face-up from the bird?s eye view are more stereoscopic and realistic.
