CES 2011

I profiled the KEF Concept Blade speaker <A href="http://blog.ultimateavmag.com/ultimate-gear/blades_of_glory/">here</A>, but since there's only one pair in the world, there was no way for me to hear it until the company brought it to CES and set it up in a room at the Hilton with an Audio Research CD5 CD player and DSi200 integrated amp. Listening to Patricia Barber in a live recording and a tenor sax with rhythm section, it sounded quite good overall, with very clean, tight low bass, but the upper bass and vocal range was slightly congested. The KEF rep agreed and said it was the room, and I couldn't disagree—hotel rooms generally make lousy listening environments.

To touch briefly on that middle ground, there was prototype of an LG mobile 3DTV that can be viewed glasses-free (autostereoscopic—easier to do for a single viewer). And there's a new LG smart phone, the Optomus 2X, said to do full 1080p. Better sit close.

But it's LG's TVs that interest us most. There are 31 new LG LCD sets, 10 of which are 3D. The Cinema 3D sets employ LED edge lighting. Three "Nano" 3D sets have full LED backlighting with local dimming. Nano technology, which is new this year, employs smaller LEDs imbedded in a membrane that also incorporates the required diffusion, making the entire structure thinner and, presumably, more easily and efficiently produced.

There are also 12 new LG plasmas, 8 of them 3D.

LG's Smart TV technology, used in many of the higher end models, is a new menu layout that simplifies use of the sets' extensive Internet features. In addition, the new LG ST600 module/set top box, available separately, can bring SmartTV to any HDTV with an HDMI input. Another approach to adding this feature to your existing HDMI HDTV is the new BD690 3D Blu-ray player, which includes an on-board 250GB hard drive plus the SmartTV platform.

But the big LG story is the use of passive glasses in many of the company's new LCD 3DTVs, rather than the active shutter glasses now employed in most current 3D sets. LG calls its passive glasses technology FPR, for Film Pattern Retarder. The sets in the LG lineup that will continue to use shutter glasses include all of the Nano models (and all of the plasma sets as well). There are many upsides to passive glasses, but downsides as well (see the following blog entry).

No prices were quoted, but all of the new sets should begin shipping by early spring.

In addition to its plasmas, LG's new LED LCDs embody the Infinia design concept and offer WHDI wireless HDMI connectivity and Skype capability. Show here from left to right are the LE8500 (backlit with local dimming) and LE7500 (edge lit with some addressable "zones"), which are both only 1 inch thick. Not shown is the flagship LE9500, which is 3D-capable with a refresh rate of 480Hz (actually, 240Hz with backlight scanning). Again, pricing was not announced, and these sets should hit the market in the spring and summer.

LG's super-slim prototype caused a stir at the company's press conference. Even with LED backlighting and local dimming (with 240 dimming zones, over twice as many as most such sets), this panel measures only 6.9mm thick&#151;that's about a quarter of an inch! This thing doesn't even have a model designation yet, so don't expect it in stores any time soon, but it sure is cool.
