A new and practical method for achieving Color Electro- Holographic Display systems was developed and tested with very promising results. In this method, holography techniques utilizing a single white light source, instead of the traditional three color laser lights, and three liquid crystal display panels (LCD) were proposed. A metal halide lamp with good specifications in each wavelength of the color components was adopted as the light source. Each of the three color light components required for the reconstruction of an image was extracted by color separation using dichroic mirrors. The separate color images were then reconstructed by the hologram formed on the LCD panels which is then combined together through eh use of a prism to form a single 3D image. Moreover, in proposal method, no lens are used by virtual-image-reconstruction. System size was reduced so far in 40 percent of the techniques by the proposal technique.
