Computex 2014: CVision's Glasses-Free 3Dby Kristian Vättö on June 11, 2014 12:10 PM EST

One of the most interesting things I saw at this year’s Computex was CVision's glasses-free 3D technology. You likely have not heard of the company before because they are currently not spending any money on B2C marketing or PR as they are focusing on selling/licensing the technology to OEMs to bring it to the mainstream market.
The way their technology works is unique. Instead of requiring a special panel or hardware, all that is needed is a custom film, or convergence of thin-film barrier as it's officially called, that is applied on top of the panel. That film along with CVision's software is able to produce a 3D experience that doesn't require glasses and to be honest, the quality was just awesome. CVision showed me a couple of short videos to highlight the 3D experience and I didn't notice that it was 3D unless I specifically looked for it. I mean, that's how smooth it was. There was no ghosting or bleeding, just sharp picture in 3D. The viewing angles were also as good as you would expect from an IPS panel -- the 3D effect didn't suffer at all even when viewed from an angle. Of course, if I moved the device or my eyes/head while playbacking the video, the smoothness was lost but as long as I held the device steady and focused on the screen there were no significant drawbacks compared to 2D.
CVision's software even supports 2D to 3D conversion on the fly, so playing Angry Birds in 3D wasn't a problem at all and it was actually very cool as the game itself suits well for 3D. Photos can also be converted to 3D and CVision showed me a couple of photos they had taken on the show floor with the phone. The camera itself was similar to what you can find inside any smartphone, so the conversion was done purely in software and the result was decent. I'm not sure if an exhibition hall is the best target for 3D photos as obviously it works the best when you are just focusing on one object but it was still clearly 3D but not as impressive as the videos or Angry Birds.
The main advantage of CVision's technology is that it can be applied to any device without the need for major re-engineering. The film itself is very thin and it is the only thing that is needed in terms of hardware and the prototype devices CVision had at their booth were as slim as any other high-end smartphone in the market. Currently the cost is about $3 per inch but CVision believes that the cost can scale with higher volumes. The technology can scale to any size but as CVision is more of a technology company than a real manufacturer, they don't have the equipment to manufacture the films for TV size screens at this moment. However, their roadmap does include a 42" 1080p TV but it might be more of a concept at this point.
All in all, this is the first time I'm truly excited about 3D. I've never been a fan of the glasses and all the glasses-free 3D technologies I've seen so far have had too many limitations to make them better than 2D in my opinion. CVision is currently in talks with several smartphone and tablet OEMs to bring the technology to the mainstream market and I sure hope the OEMs see the potential. I mean, either I got totally fooled by their (non-existing) marketing or their technology "just works".

Dirk_Funk - Wednesday, June 11, 2014 - linkCan you tell if this would require more cpu/gpu power to run smoothly? Like does it render 2 frames at once or is it simply a trick implemented in the screen?
Kristian Vättö - Wednesday, June 11, 2014 - linkI was told that it should not require any extra CPU/GPU power. The trick is the film that is applied on top of the panel -- the software itself shouldn't take much power.
JeffFlanagan - Wednesday, June 11, 2014 - linkEach field is going to be using half as many pixels as the whole panel since alternating columns are sent to each eye, so rendering cost may be the same as a 2D display. This sounds a lot like the Nintendo 3DS, but probably at a higher resolution so it'll look better.
LtGoonRush - Thursday, June 12, 2014 - linkThis could be something useful to do with ridiculously high resolution panels if we're not displaying small asian characters. As an aside on mobile displays, using an SGS3 with a SAMOLED panel has ruined me on ever using an LCD again, they just look dull and bleedy and color shifty. That said, I do notice the crunchiness from the non-RGB stripe more than I notice the low resolution overall. While obviously the later phones improved the subpixel geometry and pixel density, normal RGB stripes still look immediately better to me on fine detail.
I actually think 1280x800 SAMOLED+ would be a good res for mid-range phones, though I guess the ship has sailed and there's no cost savings from anything below 1080p. Hell, I'd much rather have 1920x1200 SAMOLED+ than a bigger 1440p SAMOLED. Maybe I'm a weirdo for thinking 16:10 is the obviously correct mobile device form factor.
Visual - Friday, June 13, 2014 - linkIf you didn't know it was 3D unless you "specifically looked for it" then it probably was not real 3D. Demo content is usually very specifically obvious 3D and I can not imagine not noticing it.
2D to 3D conversion is just impossible and not worth mentioning at all.
And how would angle of vision not impact the effect? Does it use some sort of head-tracking or how can it keep providing the proper images to each eye? This sounds so unrealistic I'm more inclined to think you were taken for a fool with some entirely 2D content...
