Micromirrors and 1D scanning produce an enlarged holographic color display
A new holographic display, which combines 2D light modulation by micromirrors and 1D horizontal scanning, enlarges the screen size and viewing angle as well as providing color images.
Three-dimensional televisions are not successful because their 3D images do not meet people's expectations. Viewers have to wear 3D glasses, and visual fatigue prevents long-duration viewing. An ideal 3D display technique that overcomes these problems is holography. People are anticipating holographic displays because they have seen them depicted in science fiction movies. As development of 2D display technologies has been reaching saturation, many research groups around the world are developing holographic displays.
