Integral Imaging 3D Display without Dedicated Glasses

The integral imaging system is based on the principle of sampling and collecting the light reflected from an object, and then precisely reproducing the light through a display to realize smooth and natural images.

Toshiba’s new algorithm simultaneously creates nine parallax images for the liquid crystal display (LCD) panel and controls and optimizes light emission and direction from the center, right, and left of the screen to realize a wide viewing angle. This technology results in an optimized display of high-quality 3D images whatever the position and angle to the screen of the viewer.

The high-definition (HD) LCD panel, whose pixels are specially designed for moiré suppression, has approximately four times the pixels of a full HD panel; i.e. 8.29 million pixels. It can display elemental images carrying information from nine parallax images created from a single frame in real time. The resolution of the final 3D image is 1280 × 720 pixels.

The glasses-free 3D REGZA™ GL1 series employs the above technology.

Part of this work was supported by the Japanese Ministry of Internal Affairs and Communications under the “R&D of 3D Imaging Not Requiring Glasses” Project.
