    Toshiba announces glasses-free 3D TVs - again

    Toshiba has announced large-screen glasses-free 3D TVs at CES 2011, showing 56" and 65" prototypes.

    Both feature a LED-backlighted panel with a 4096 x 2160 pixel resolution (4k2k). The Toshiba Integral Imaging technology applied to its glasses-free 3DTVs works with multiple view points that enable the human brain to see 3D images, while also allowing for a wide viewing angle. Toshiba claims that thanks to its viewpoint overlay technology, users can even move their heads whilst watching 3D content without compromising the 3D effect.

    Toshiba showed glasses-free 3D TVs as long ago as October (see here). Admittedly, these were 12" and 20" models, and have not been on sale outside Japan. Toshiba's first large screen 3DTV models over 40" featuring glasses-free technology are expected to be available within Europe in 2011.

    Well, we'll believe it when we see it. Though the products for the European market will use Toshiba’s powerful CEVO-Engine, which is able to provide the extremely high-calculation power needed to run glasses-free 3D technology on the TV’s large screens, we're not convinced that the autostereoscopic system will work acceptably well in a domestic environment. Also, the 4K resolution sets will be horrendously expensive. More likely, the system will be popular on the glasses-free 3D laptops and mobile devices Toshiba has promised. Anyway, we're happy to try out anything that avoids having to use those pesky glasses...

    Jeg er enig i at dette er en spennende nyhet. Spørsmålet er vel hvor godt teknologien virker...

    Ja jeg har jo sagt hele tiden at 3D med briller har ingen stor fremtid. Hvem gidder/klarer å sitte en hel kveld med 3D-briller for å se på TV?

    De som ønsker high-end 3D.

    Løsninger som benytter passive briller eller ingen briller i det hele tatt vil i all nærmeste fremtid representere low-end 3D.

    Tipper brilleløse 3D TVer (50"+) blir det store på CES 2016
    Kanskje allerede 2015
    Må muligens vente til 2017
    I verste fall 2018
    I beste fall 2014

    Lies, Errors and Myths About 3D-Part 3

    -Glasses-Free Full HD 3D TV is just around the corner.

    Numerous technical issues exist with glasses-free (called auto-stereoscopic 3D) displays. Current technology and standards divide the resolution by the number of viewers. For example, with four glasses-free viewing positions, each viewer sees just one quarter of full resolution. Many other technical issues have to be addressed before multi-viewer, full resolution, auto-stereoscopic 3D TV becomes a reality.

    Later this year you’ll see glasses-free single viewer, hand held 3D video games and computer monitors since single “sweet spot” viewer positioning is practical. Best early “guesstimates” for multiple viewer Full HD 3D is 10 years, although set makers may experiment with three or four viewer systems somewhat sooner.
    Samsung says glasses-free 3D years away from relevance | TG Daily

    The head of Samsung's display unit is telling consumers not to get too affixed to this growing idea of glasses-free 3D TV sets, because it won't really take off until at least 2015.

    "I believe that [glasses-free 3D technology] will be possible on cell phones and other mobile devices, or monitors that require smaller displays...but supplying 3D TV without glasses will not be (available) in the next five to ten years," said Samsung Electronics BK Yoon, the president of its display division.

    Researchers say it could require displays with four times today's resolution to deliver without visible artifacts high def stereo 3-D that can be seen by the naked eye.

    Content producers say the situation is even worse on their end. It will require at least eight lenses per camera, and perhaps dozens, to properly capture video that can be seen in 3-D without glasses.

    Technicolor showed a demo of so-called auto-stereoscopic 3-D TV at CES using its interpolation algorithm. However, it had a relatively narrow viewing area of ten degrees so users saw blurring when they moved their heads.

    "It could require 8K resolution screens to do it well, so this could be 10-15 years away," said Thierry Borel, a researcher at Technicolor working on the project.

    Autostereoscopic 3D Displays

    Now, there is a lot of talk going on about this type of solutions that do not require the user to wear glasses in order to be able to see the 3D image. It certainly sounds nice and more convenient than having to wear some sort of glasses like with the other solutions, however don’t think we are ready for going to autostereoscopic 3D displays for now. This technology is still quite new and not developed well enough to satisfy general demand and requirements, including in therms of price. The autostereoscopic displays have a number of issues that need to be corrected, before they can become the mainstream technogoly for 3D and that will probably require at least 5 more years. I’m talking about the limited number of viewing positions they offer (the place where you have to be to be able to see the depth of the image being displayed), the lower resolution (this is associated with the number of views you get) and most of all the price has to become much more affordable than it is at the moment. Sure, there are number of small portable multimedia devices that do have an autostereoscopic 3D display and they are not much more expensive than the rest of the non-3D supporting equivalents. However these displays are with a small size, small resolution, usually a single viewing position and due to their quite small size they do not come that expensive. But for a multiuser solution in the form of a big 3D HDTV the price even with what the current technology offers will be at least a few times more expensive than a good 3D-capable LCD or Plasma HDTV with shutter glasses. So there is some more time for that technology to catch up and if you want to experience stereo 3D now, then you should not be waiting for the time of autostereoscopic 3D solutions to come.

    Auto stereoscopic 3D Technology

    A3D displays currently face a number of obstacles to broad consumer adoption. Viewers can only see the 3D images at a certain range of distances (depending on the screen size) and within a very narrow viewing angle (around 20~40 degrees). Another barrier is the high cost of making an auto stereoscopic screen; the cheapest 22” A3D monitor is priced above $3,000 and a 42” A3D monitor can cost as much as $8,600. (A 46” SONY stereoscopic 3DTV, on the other hand, retails for $1,999.) Most importantly, A3D and stereoscopic 3D content are not interchangeable (content produced for one kind of display cannot be viewed on the other), and there is currently no common platform for producing A3D content. For all of these reasons, the application of A3D monitors has been limited to business-to-business markets such as advertising and digital signage, gaming and entertainment machines, and scientific and medical visualizations.

    "I'm excited to see how the Nintendo 3DS is going to work," Langson says. "I have seen autostereoscopic 3D. It's impressive, but there are limitations. I think that's why everybody hasn't gotten there yet. Hopefully, down the road we'll see autostereoscopic 3D everywhere."

    "Autostereoscopic is really where we're all going to be 10 years from now," Long says. "We'll see glasses for about the next 5 to 8 years, tops, and then autostereoscopic will take off after that."

    Så for første gang en 3D-tv i dag, ble veldig imponert. Men det var med briller. Forstår ikke helt hvordan de skal få til samme effekt uten.

    Spent på om det holder med 4096 x 2160 oppløsning, eller om det må 8K display til for å fungere optimalt for flere enn 1-2 i sweetspot.

    Fungerer dagens 3D blu-ray standard med brilleløse tver, eller må det endring av standarden til ?

    Hvis det ikke trengs 8K og endring av 3D BD, så kan kanskje brilleløs 3D-TVer komme de nærmeste år. Ingen tvil om at brilleløs er the Holy Grail for 3D-TV.

    Spent på om OLED kommer i 2012-2013 med full-HD og passive briller. Det kan bli veldig bra!

    Toshibas visning av 3D uten briller sugde isbiter. Det var totalt ubrukelig. De som har kommet aller lengst med 3D uten briller var sony. De hadde flere kule greier, blandt annet en liten bærbar BD-spiller med 3d display uten briller og en OLED-skjerm uten briller som virker forbløffende godt. Dette er uansett bare snakk om prototyper. De hadde også en slags brille med headset hvor man fikk 3d som også var kul.

    Sugde isbiter... hehe. Det var en fin måte å si hva du mente Jørn. Uansett om et par år så har vil vel gode produkter uten bruk av briller forhåpentligvis..
