Abstract

We have been developing the projection type display system[1]. In the case of projection type display, it needs to use the screen in order to project the image clearly. We could get the wide viewing area using the mist screen[2-4]. However, the image with mist screen was flickered by gravity and air flow. Then we considered to reduce the flicker of the image and we found that flicker can be reduced and viewing angle became more large. This time we report the large viewing angle projection type display system using screen made up with very small particle size smoke and flow controlled nozzle. Hence, at first we considered the most suitable particle for the screen and then the shape of screen and then we constructed the array of flow controlled smoke screen. By the results of experiment we could get considerably high contrast flicker-less image and get the viewing angle more than 60° by this flow controlled nozzle attached new type smoke screen and moreover we can get the walk through type display with this method and make clear the efficiency of this method.
