Abstract

Volumetric displays are those of the displays which can represent natural 3-D images. Unlike conventional 2-D displays, volumetric displays have depth information and enable 3-D images to be observed from any surrounding viewpoint. One of the methods to make volumetric displays represent color and motion 3-D images is an electrical controlling. Actually, we can easily get electrically controlled volumetric displays consisting of arrays of light-emitting diodes arranged in a 3-D layout as products.
