CES 2012

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 eye—much 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.

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.

Griffin’s new smartphone universal remote control uses Bluetooth to send commands to an IR emitter that sits near your home theater system. As a result, the $69.99 Beacon doesn’t require the user to attach any dongles or special transmitters to the phone (something that makes other smartphone remotes a pain in the butt). The IR emitter is battery powered, so it can be placed wherever is most convenient without the need for running a power cable to it. Models are available for both iOS and Android smartphones.

The 46-inch, LED-edgelit UW46 from Westinghouse incorporates 120Hz operation but no frame interpolation and sports a super-slim, silver-edged bezel. It should be available this quarter for $700. The company says that 46-inchers were the best-selling large-size TVs in 2011, a trend I expect to continue at this price.

Westinghouse's first foray into 3D, the 47-inch W473D uses conventional CCFL backlighting and passive-polarized glasses. It should be available in the second quarter of this year for $900. The prototype pictured here exhibited severe crosstalk/ghosting, so I'd say the company has some work to do before it's ready for prime time—and even then, it might not fly that well at big-box stores, where 3D is not in much demand.

An ambitious Chinese manufacturer of LCD sets, that's who. The small booth had demos 3D sets and an innovative 21:9 flat panel set optimized for 2.35: 1 movies—with black windowbox" bars at the sides for 16:9 material. Reportedly, TCL makes sets for VIZIO, which makes sense seeing that VIZIO is nearly set to release 21:9 sets. The only puzzle here remains why my camera rendered the TCL logo on top a red-fringed yellow, when the sign was clearly solid red.
