Most manufacturers showed lines that that commercially topped out at 55" or so. Sure, there we plenty of 80" and 108" demos, but these aren't generally consumer products. That said, we saw a few exceptions.
Sony did show a 70" LCD, but look at the $33k price:
SONY UNVEILS 70-INCH BRAVIA LCD; WORLD’S LARGEST HDTV COMPLIANT WITH x.v.Color
Technology Establishes New Standard for Color Reproduction
LAS VEGAS (CES Booth #14200), Jan. 7, 2007 – Sony Electronics today introduced a 70-inch flat-panel, high-definition LCD television, the world’s largest TV compliant with x.v.Color™ technology here at the International Consumer Electronics Show in Las Vegas.
The new BRAVIA™ KDL-70XBR3 model is now available for pre-order at select Sony Style stores and select authorized retail outlets including Video Audio Center, Home Theater Store, ABT Electronics, Little Guys, Myer-Emco, Bjorn’s, and Listen Up.
It has the largest screen size in Sony’s market-leading BRAVIA LCD line. The new extends the boundaries of picture quality due to a combination of full HD 1920 x 1080 progressive resolution and Motionflow™ 120 Hz technology with motion compensation, as well as a 10-bit panel and Triluminos™ LED backlight.
Image quality is enhanced further with the new xvYCC technology, which Sony has branded x.v.Color. This technology was established as an industry standard by the International Electronics Commission in January of 2006.
The standard expands the current color data range of video by approximately 1.8 times (based on the “Munsell Color Cascade” a universal color chart defining the colors of natural objects and is used to evaluate color expression capability of displays). The result is the television’s ability to display more natural and vivid colors similar to what the human eye can actually see.
In addition to the x.v.Color compatible television, Sony also introduced four new high-definition Handycam® camcorders here at CES that also feature this new technology.
With today’s debut of the 70-inch BRAVIA LCD set, Sony’s line of flat panel televisions now encompasses screen sizes of 70, 52, 46, 40, 32, 26 and 23 inches.
