Volumetric displays are one 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 viewpoints. However, the conventional electrically controlled volumetric display has an inevitable issue that we call “occlusion” because it needs an electrical wiring for power supply. The issue prevents the volumetric displays from being more high-definition and reduces an image quality. Therefore, in this study, we proposed an optically controlled volumetric display based on quantum dots (QDs) which don’t need electrical wiring and demonstrated it. We fabricated a prototype of the QD-based volumetric display composed of 5×5×5 voxels. We confirmed the volumetric display can represent multi-color which is not only red and green, but also yellow (a color between red and green). From experimental results, we confirmed that the QD-based volumetric display can represent multi-color 3-D images without the issue of occlusion.
