Recently, many type of 3-D displays are now being developed. We want to see 3-D moving image with
comfortably and more expanded depth, Holography is different from the other 3-D display because
natural stereoscopic image can be obtained. We have once developed a electro-holographic display using
virtual image. But the viewing area is so small because the pixcel size of LCD is not so small.
This time we developed the projection type electro-holographic display system. In the case of
projection type holography [1], it needs to use the 3-D screen in order to project the reconstructed image
clearly and viewing angle becomes wide. We developed the electro-holographic display system using mist
3-D screen. However, a reconstructed image with mist 3-D screen was flickered by gravity and flow of air.
Then we considered to reduce the flicker of the image and we found that flicker could be reduced using
flow controlled nozzle.
Hence, at first we considered the most suitable shape of 3-D screen and then we constructed the array
of flow controlled mist 3D screen. By the results of experiment we could get considerably high contrast
3-D moving image and get the viewing area more than 30°by this flow controlled nozzle attached new
type mist 3-D screen and make clear the efficiency of this method.

Computer holographic stereogram (CHS) is useful for holographic 3D TV because it is constructed from
the multi horizontal viewpoint plane images and is compatible to the multi-view point images. Each
hologram is recorded as a slit hologram (element hologram) but total viewing area and the number of the
element holograms have been limited to some extent by the size and the resolution points of LCD.
Therefore we used two LCDs for making CHS and deposited them horizontally and increased the viewing
points to two times and extend the display area to satisfy the binocular parallax. We considered how
viewing area becomes extended. We consider how we could improve the characteriostics of the images of
CHS. From now we consider the condition such as transmission and real time calculation about the
3D-TV
