Zecotek Granted U.S. Patent for Switchable 3D/2D Optical Imaging System
3D-News Posted: Friday, November 6, 2015 (5:52 UTC) | Posted By: Webmaster

Zecotek Photonics Inc., a developer of leading-edge photonics technologies for industrial, healthcare and scientific markets, announced that the U.S. Patent office has granted U.S. Patent No. 9,055,288 to Zecotek for technology related to the Company's switchable 3D/2D optical imaging system. This patent adds to the global portfolio of patents, including U.S. patent number 7,944,465 covering Zecotek's glasses-free 3D auto-stereoscopic display system.

"This U.S. patent marks another important step in our continued efforts to provide the best-in-class glasses-free 3D displays and monitors," said Dr. A.F. Zerrouk, Chairman, President, and CEO of Zecotek Photonics Inc. "The patent covers the significant improvements to our switchable 3D/2D display technology which meet the practical needs of OEM's and end users. Our 3D display technology allows for switching between 3D and 2D modes without loss of resolution, and displaying 3D and 2D content simultaneously. The patent also covers technology which significantly broadens the capabilities of specialized 3D display applications such as fundamental research and medical imaging. We are working closely with OEM's within well-defined markets and will continue to maintain an aggressive IP development program in parallel with our efforts to meet market requirements."

The 3D/2D switchable optical imaging system further improves the core capabilities of the 3D display technology by introducing a software-selectable full-resolution 2D mode with viewing angles and dynamic range/colour depth on par with conventional 2D displays. The patent also covers technology for both 3D and 2D modes, dynamic adjustment of viewing angle, number and width of viewing zones as well as the functionality to dynamically control the positioning of different viewing zones.

Patents have been granted to Zecotek for its 3D display system in the United States, China, Europe, Eurasia, Russia and Australia. Other patents have been filed and are pending in Japan, Korea and India.

About Zecotek's 3D Display System
Zecotek's 3D Display System is based on the auto-stereoscopic principle, but with substantial innovative and patented improvements and represents a new and unique generation of 3D displays. It has the capability of simultaneously presenting 3D and 2D images on the same screen, and for separate views at different viewing angles. Zecotek's true, auto-stereoscopic 3D2D display 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 which can occur with polarized and shutter glasses used with other commercial systems. Furthermore Zecotek's 3D display features the preservation of the base resolution in every perspective view irrespective of the number of such views. This is not true for any other glasses-free displays where the base resolution is divided by the number of views. Zecotek's white paper on 3D display technology is available on www.zecotek.com.

MasterImage 3D Successfully Invalidates RealD's Chinese Utility Model Patent
3D-News Posted: Friday, November 6, 2015 (5:26 UTC) | Posted By: Webmaster

MasterImage 3D, a worldwide leader in 3D display technologies for digital cinema, successfully invalidated RealD's Chinese utility model patent by filing an appeal before the Chinese Patent Re-examination Board (PRB). The Chinese PRB agreed with MasterImage 3D's claim that RealD's patent lacked inventiveness and failed to meet the requirements for patent protection. As a result, MasterImage 3D will continue to sell its high-brightness HORIZON3D product line in China.

In October 2014, MasterImage 3D appealed the grant of RealD's utility model patent CN 203433207U for 3D beam-splitting, polarization technologies. In its appeal, MasterImage 3D documented the lack of novelty and inventiveness of RealD's patent being brandished by RealD in an effort to block other 3D technologies from the Chinese market. On May 7, 2015, the Chinese PRB declared that RealD's Chinese patent is invalid as a whole.

It is the second victory of MasterImage 3D after successfully invalidating RealD's utility model patent in Russia. On March 27, 2015, the Russian Patent Office also sided with MasterImage 3D and invalidated RealD's utility model patent in Russia.

With this victory in the Chinese PRB, RealD's effort to keep the HORIZON3D out of a competitive Chinese marketplace has been denied. MasterImage 3D will continue to sell its HORIZON3D high-brightness, triple-beam product line in China and throughout the rest of the world.

"Chinese moviegoers demonstrate an impressive enthusiasm for blockbuster, immersive 3D cinema," said Younghoon Lee, Chairman and CEO of MasterImage 3D. "Our HORIZON3D system allows the Chinese market to show the world's best 3D movies in the most visually stunning, premium quality 3D. This is a commitment that MasterImage 3D cherishes and plans to continue for years to come."
