The Smart Crystal Pro polarization modulator from a new (to us) company called Volfoni (which also makes both active and passive 3D glasses) can take your single chip active glasses DLP 3D projector and turn it into a passive glasses 3D projector. The brochure says it can do this for any 3D single lens projector, but the device has only been verified effective on DLPs.
What it does, in effect, is to substitute rapidly alternating polarization of the filter, which is positioned in front of the lens, for the switching of active glasses. You'll need a connection from the sync transmitter output in the projector to the Crystal Pro to make this work, or alternately DLP Link in the projector (DLP Link is a process that uses rapid interframe bursts of light from the DLP projector that normally triggers active glasses). (If your projector has neither, that is, no DLP Link and an on-board sync transmitter, it will not work, as I understand it. You'll also need a screen that preserves polarization. Estimated cost will be $1500 for the Crystal Pro itself, or $2000 for a package including both the Crystal Pro and a slide that can automatically move the polarizer out of the way for 2D material.
Toshiba demonstrated how a 4K panel can improve the resolution. The photo above can't do it justice, of course (the 4K panel is on the left), but you could clearly see the difference on some material. Of course, the images were stationary of moving very slowly; motion would likely degrade any resolution improvement.
Toshiba was showing its latest prototypes of glasses free 3D. In comparison to last year's demos, the results were much improved. The secret appears to be the use of a 4K LCD panel, which ups the convergence available to each eyemuch like the new, jumbo 4K set shown by LG appears to improve the (passive glasses) 3D performance of that set. If you’re watching 3D alone, the set tracks your head position and adjusts the picture to provide optimum performance. In a group showing, the 3D works properly only in 9 individual regions across the front viewing area. A small circular bug at the top center of the screen (visible in the photo) tells you if your head is in a hot spot for 3D. Toshiba expects to have sets in stores in late 2012. But the use of a 4K panel suggests that the first such sets will be expensive, so I wouldn't hold off purchasing a 3D set hoping to have a cheap, glasses-free alternative real soon now.
At its press event Monday before the main show floor opened, Panasonic was almost silent on the performance details of its new sets (none of the big manufacturers were making a big deal about improved picture quality, though if pressed they will admit to evolutionary improvements in their new 1920 x 1080 models). But Panasonic was big on improved convergence. We certainly aim to find out in our reviews when the new sets become available.
90% of the Panasonic’s 2012 models offer Web connectivity, which is clearly the main theme song of this year’s CES. At the press event Panasonic also announced a working agreement between Panasonic and MySpace (!?) for enhanced social network connectivity, such as texting with your friends while you all watch the same movie. I can see this for sports, but for films? And can this joint effort resurrect a moribund social networking service that has clearly lost its trench war with Facebook? Panasonic and MySpace certainly hope so; they even trotted out celebrity Justin Timberlake at the press event to help promote this new launch. Timberlake co-starred in a recent movie about the origin of Facebook; now he’s helping to (possibly) reinvigorate MySpace.
With Internet connectivity, you can now play competitive video games over the Web. How long before such games become championship spectator sports we can watch passively on HDTV, bringing us full circle? With 300 channels, maybe they have already and I’ve just missed it.
Later at the show we obtained more details about Panasonic’s 2012 sets. New models in the VT50, GT50, and ST50 series of plasma sets will make up the meat and potatoes of Panasonic’s updated designs, expect to be available in 2-3 months if past delivery schedules are maintained. There will be an expanded range of new Panasonic LCD IPS designs as well. In fact, there are 15 new LCD models, 13 with LED backlighting. Seven of the LCD sets are 3D, including three in the ET5 series using passive glassesPanasonic’s first departure from full HD 3D (passive glasses sets cut the vertical resolution seen by each eye in half in a 1080p set). In addition, the LCD line now includes 47- and 55-inch sizes. Previous Panasonic sets at 42-inches and larger have all been plasma designs. With LCD now dominant in the market, could Panasonic be hedging its bets?
While not as svelte as the company’s 55-inch OLED prototype discussed below, LG’s new lineup of Smart LED/LCD sets is still just a bit over an inch thick with a 1mm thick bezel framing the screen. The top of the line Nano sets, available several sizes up to 84” in size. The Nano designs are full backlit local dimmers, utilizing LEDs impeded into t thin membrane that allows for superior backlit local dimming in a thinner design. LG’s magic remote has been improved, allowing not only pointing but also both gesture and voice recognition. And like all the HDTV manufacturers at the show, LG’s Smart technology offers further enhancements in convergence and connectivity with Web-based sites and features.
That 84” model is unique in that it is a 4K design. Despite the lack of 4K sources, 4K offers significant advantages for LG’s passive glasses approach to 3D. Specifically, it can present a full 1920 x 1080 resolution to each eye, unlike the half vertical 3D resolution on conventions 1920 x 1080 sets.
While no price or availability date was announced for LG’s 55” OLED HDTV, its prototype drew big crowds at the opening press conference of the day. So big, in fact, that you can’t see the set with the madding crowds pushing in for a closer look.
What we do know is that the set uses what LG refers to as 4-Color Pixels (red, green, blue, and white) together with a Color Refiner for color consistency over a wide viewing angle.
An eye-opening infinite contrast ratio is also claimed. This is possible because OLED is a self-illuminating technology in which the individual pixels, in theory, can be completely turned off. Response time is also said to be 1000x faster than in LED/LED sets.
LG’s OLED TV is as pleasing aesthetically pleasing as it is technologically trend-setting. It’s passive 3D-capable and an incredible 4mm thin (about one-sixth of an inch) and a feather-light 17 lbs.
Panasonic was demonstrating its new PT-AE7000 3D projector ($3500) on a 100-inch (diagonal) Joe Kane Affinity screen (gain 1.1) from Da-Lite. Granted that the 3D program material was all animated, which is almost always impressive on a video display, it nevertheless looked superb. The trailers from Toy Story 3, The Lion King, and Beauty and the Beast all had me salivating for the full releases (scheduled for October--at least for the latter two). It was interesting to see that the 3D re-processing of the older hand drawn animation on Lion KIng and Beastlooked very good, with a minimum of the layered cardboard cutout effect. Kudos here to both Disney and Panasonic.
The new Martin Logan Montis ($10,000/pair) was producing compelling music in one of the shows isolated (sort of) sound rooms, ably assisted by a pair of humongous McIntosh amps (for newbies, that's a "tosh" without the "a" and without the iPod).
