Panasonic’s New TY-EW3D3 Active Shutter Glasses For 3D HDTVs

August 3rd, 2011 · 5 Comments · General 3D News


Last year, when the first HDMI 1.4-capable 3D HDTVs from Panasonic started appearing on the market, the Japanese company did not have the best active shutter glasses available, but they are constantly improving on that. The second generation of active shutter glasses brought some of the needed improvements and now we are about to see the third generation of Panasonic active shutter glasses for their 3D HDTVs, namely the TY-EW3D3 series, expected to be available this September. The new glasses should be available in three sizes (small, medium and large) with a different product name for each, respectively TY-EW3D3SW, TY-EW3D3MW and TY-EW3D3LW (S, M and L). The small and medium models have a weight of just 26 grams and the medium will be one gram more at 27 grams, so you can expect these do be very lightweight. The glasses come with a built-in rechargeable battery that should provide you with up to 25 hours of continuous use with a full charge that is taking approximately 30 minutes, and there is a quick charge functionality built-in that can be quite handy. With just a two minute quick charge you can get up to 3 hours of use, so you can easily watch a whole movie in 3D even if you forgot to charge your glasses and they got discharged.



But the most interesting new feature built into the new TY-EW3D3 shutter glasses from Panasonic is the 2D mode that allows you to switch the glasses into a special mode showing you the 2D version of a 3D movie being played on the 3D HDTV. This is done by activating both shutters of the glasses to show you only the frame intended for the left eye, so that you see only the left eye image in both your eyes and the result is that you get to watch the movie in 2D. I’ve already demonstrated how this is possible with a pair of Nvidia 3D Vision shutter glasses a while ago and that it actually works quite well, but then again this solution also opens other possibilities like screen sharing in 2D mode for example.

The new active shutter glasses should also offer a 10% better improvement in terms of image brightness, meaning that the lenses of the glasses will block less light as compared to the previous models. It is interesting to note that the new Panasonic active shutter glasses are the first using the new M-3DI standard announced by the company not too long ago, so in theory they may be able to work with other non-Panasonic 3D hardware if any other company produces compatible devices with this new standard.

Panasonic and XPAND 3D Pushing a New Standard for 3D Glasses

March 29th, 2011 · 2 Comments · General 3D News


Panasonic and XPAND 3D announced that they have formulated M-3DI, a new standard for 3D active-shutter eyewear products that is supposed to bring compatibility among 3D TVs, computers, home projectors and cinema projection. Currently the M-3DI standard uses infrared communication technology, but radio communications is to be considered for the next step of the evolution of the standard, if there turns out to be such. Licensing of the M-3DI technology is expected to begin next month, providing a communication protocol between 3D active-shutter eyewear products and 3D-capable hardware by interested parties. Panasonic is among the top consumer electronic companies that are pushing 3D technology and XPAND 3D is a manufacturer of 3D equipment, so the combination sounds good, but how well will the new standard turn out is still yet to be seen…

Among the other companies that have agreed to participate in supporting the new standard are: Changhong Electric, FUNAI Electric, Hisense Electric, Hitachi Consumer Electronics, Mitsubishi Electric Corporation, Seiko Epson Corporation, SIM2 Multimedia S.p.A. and ViewSonic Corporation. Notice that no other big CE brands that are pushing 3D technology such as Sony, Samsung, LG and others are present in this list and that can be a serious problem for the wide adoption of the M-3DI standard and fulfilling the actual goal of the project. Without an active role and cooperation of all top manufacturers of 3D-capable hardware and that includes all major 3D HDTV makers there is no chance of getting one universal standard for the glasses and that will mean that we are still going to have compatibility trouble with different 3D devices. I’ll keep tracking the development of the M-3DI standard although I’m quite skeptical about its wide enough adoption at this point.
