In addition to being thin, green was prominent. At every exhibit, you saw TVs hooked up to watt meters demonstrating how little power new models consumed. Primarily the new power-saving TVs relied on motion and light sensors and LED backlighting as a means of reducing electricity use while maintaining high brightness and contrast while being viewed. Sony’s KDL models (in 40- and 46-inch versions) used a new micro-tubular hot cathode flourescent lamp, rather than the traditional cold cathode flourescent lamp to reduce power by about 40 percent.
The best of the LED-based TVs included some form of local dimming technology, which allows the LED lights to be controlled for separate areas of the screen, in some cases individually, allowing much more accurate colors and contrast. We saw LED TVs from Sony, Samsung, LG, Toshiba and Sharp. Samsung’s 7000 series in particular looked great with the Touch-of-Color affect to the surrounding bezel. It has the unique ability to be hung on a wall with wires, similar to a picture frame. JVC also showed a TV that went on the wall like nothing else we’ve seen—magnets.
A couple of companies were showing off 3D televisions, and while the demos were impressive, we don’t expect all the parts to come together for a few more years.
