Singapore and Richmond, BC, Canada--U.S. patent number 7,944,465 was granted to Zecotek Photonics for its glasses-free 3D autostereoscopic display system.

Singapore and Richmond, BC, Canada--The U.S. Patent and Trademark Office granted patent number 7,944,465 to Zecotek Photonics (TSX-V: ZMS; Frankfurt: W1I) for its glasses-free three-dimensional (3D) autostereoscopic display system. Zecotek Photonics is a photonics technology company developing high-performance crystals, photodetectors, medical lasers, optical imaging, and 3D display technologies for commercial applications in the medical diagnostics and high-tech industry. Founded in 2003, the company has three distinct operating divisions: medical imaging, medical lasers, and 3D display and labs located in Canada, Singapore, and Russia.

Zecotek's display can simultaneously present 3D and 2D images on the same screen, and for separate views at different viewing angles. The autostereoscopic 3D2D system requires no eyewear and has an effective viewing angle of 40 degrees with 90 concurrent perspectives allowing for multiple views at the same time. Another unique feature of the Zecotek system is constant motion parallax within the viewing angle. Motion parallax eliminates the sense of imbalance and dizziness during normal observation that can occur with polarized and shutter glasses used with other commercial systems.

"Protection of our intellectual property is of the highest priority to Zecotek and receiving the U.S. patent for our glasses-free 3D display system represents a key step in the commercialization of this unique technology," said A. F. Zerrouk, chairman, president, and CEO of Zecotek Photonics. "With a number of significant technical barriers preventing the development of a true 3D display, the U.S. patent protects our innovative glasses–free approach to 3D display technology. Our 3D auto-stereoscopic display offers a real volumetric 3D viewing experience with one of the widest viewing angles and the highest resolution compared to competing technologies. We will continue to pursue full commercialization of this technology with a strategic partner."

The new patent covers the use of equipment for the reproduction of static and moving 3D stereo representations with the capability of recording and transmitting stereo representations of 3D scenes. Patents have now been granted to Zecotek for its 3D display system in the United States and Australia. Patents have been filed and are pending in Japan, China, Korea, India, Russia and major countries in Europe.
