Spatial 3-D display system based on sequential effect

In order to generate a true 3D image providing viewers true depth cues, such as binocular parallax, accommodation and convergence, motion parallax, etc, a volumetric three-dimension display system has been developed based on the time sequential display of a rotational two dimension LED array which is controlled by a high speed microchips sequentially. The 3D data source is obtained from 3DS files, and mapped to the 2D LED panel by space encoding. Due to the visual persistence, observers could see full three-dimensional images without the need for special viewing glasses. The system can provide above 200,000 voxels (volume pixels) in a cylinder display space with a diameter of 305.6 mm and a height of 76 mm. The principle of the system and the display performance have been investigated by relating the display panel pixel arrangement and the reconstructed three-dimensional image. The display results of real animate three-dimensional images are presented and proved that the volumetric display system has the wide-ranging application prospect.
