New glasses-free 3D tech uses per pixel prisms for zero crosstalk, audience flexibility
Try as manufacturers might, attempts at autostereoscopic (glasses-free) TV have been subpar; existing tech typically makes for messy images due to ghosting, only provides a 3D effect if you're standing in one of a very few predetermined spots (usually 8-10 viewing angles, though we've heard of 64), and reduces display resolution -- all because only some pixels can be seen from each spot. With the occasional exception, it's not terribly impressive. Scientists at the National Chiao Tung University in Taiwan are looking to change that. Rather than block light with a parallax barrier, their screen uses a matrix of specially cut prisms to reflect it, reducing ghosting to nil and maintaining display resolution by sending the same image to each viewer. Though there are still a fixed number of viewing zones, the prisms are so tiny that manufacturers can simply add more prisms to each pixel to increase that number -- with 11 prisms per pixel, researchers say such a system could support 100 simultaneous 3D moviegoers. We've no word on whether the tech is affordable or when we'll see it, but we expect it to handily beat cyborg eyeballs to market.
TCL completes the no-glasses 3D trifecta at CES
Add one more piece of tech to your glasses vs. glassless 3D display battlemap, as TCL was showing off this autostereoscopic display in an odd reflective frame at its CES booth. Around the corner from a conventional RealD shutter glasses setup, it whipped through several animated 3D renderings similar to those from Alioscopy and Magnetic3D. The frame made it hard to tell but it seemed to have a little less pop than the competition, with slightly better clarity. All the glassless displays we saw this year used similar lenticular lens technology applied to 1080p HDTV screens to achieve their affect, with mostly similar results, with so many players, there should be plenty of billboards and in-store opportunities for you to get a look yourself soon enough. %Gallery-82710%
Magnetic3D glasses-free 3D eyes-on
We didn't get a chance to check out the whole line of Magnetic3D autostereoscopic displays, but a trip to the International Gateway got us a quick glance of this challenger to Alioscopy. It claims up to 9 viewing angles, an improvement over Alioscopy's 8, plus support for compressed MPEG-4 video and a smaller video player, key for the digital signage market these displays compete in. We did detect a bit more "pop" from greater distances and angles than competing tech, but unfortunately what we didn't see was any indication this technology is any closer to being ready for regular TV watching. The 3D film over the demo 1080p LCD still drops the resolution somewhat and makes 2D viewing a messy blur, so for the time being, these displays popping out ads from streetcorners or slot machines will have to do. %Gallery-82620%
xyZ autostereoscopic display takes the glasses out of 3D for (relatively) cheap
We still have no idea how to bring this tech home, but Zero Creative has recently been showing off its glasses free 3D setup, bringing 1080p 3D to events and retail locations near you. Overall this autostereoscopic display seems to be offering better contrast ratio (1,800:1) than the (now discontinued) WOWvx based Philips screens we were drooling over last year, at a much lower price of just €6,795 for the 46-inch version. We won't claim to understand how the lenticular lens works, but without a way to experience the 3D effect on your own screen you'll have to take the word of overly excited conference attendees on how impressive it is, videos are embedded after the break.[Thanks, Addae]
NY storefront hosts the first no-glasses 3D LCD ad
Like 3D, don't like glasses? Check out 750 7th Avenue at 50th Street in New York for the Snickers display where Inwindow Outdoor and Alioscopy have teamed up for the first 3D LCD ad on a storefront. The 42-inch panel uses an 8x recorded autosteroscopic (read: no glasses) 3D process to make the catchphrase jump off the wall at passers-by. The installation debuted May 6, and for the small cost of being marketed to vs. the now-shelved €18,000 Philips screen we once lusted after, it's a cheap way for us to get a peek at the future.
Toshiba Matsushita Display teases handheld, high res, no glasses 3D
We swore we wouldn't fall for tech demos of Toshiba Matsushita Display's sexy optically compensated bend LCDs and their CRT-like ultra wide viewing angles and high refresh rates ever again but by adding autostereoscopic 3D (read: no glasses necessary) we're falling in love all over again. By adapting a 3D film for use with 3- and 9-inch displays, this year's CES demo promises simultaneous 2D and 3D viewing on the same display in high res. How close is OCB's curved, rather than horizontally or vertically aligned liquid crystal approach to reality? Your guess is as good as ours but for now we'll wait for some eyes-on time and throw it on the wait-and-wait-and-see heap with SED and the rest.
