LG, Sony Add LED LCDs at CEDIA Expo 2009
Many of the companies' new models are edge-lit for slimmer designs.
LG SL90 LED LCD
It's safe to say that LED-backlit TVs are here to stay. What form they take is the question.
LG and Sony have revealed new LCD TVs using LED technology, though four of the five models the companies announced at CEDIA Expo 2009 will be edge-lit by LEDs only on the sides of the screen.
LG's 55-inch 55LHX wireless HDTV model is the only one backlit by a full array of LEDs. The full array of LEDs is capable of local dimming, in which clusters of the energy-saving LEDs can be shut off during dark scenes, enhancing the picture's contrast and saving even more energy.
Consumers will pay for that level of performance and eco-friendliness, along with the wireless functionality, to the tune of $4,799.
LG's edge-lit LED LCD TVs include the slender, 1.15-inch-thick 42- and 47-inch SL models ($2,599 and $2,099). By edge-lighting with LEDs, manufacturers can make the sets slimmer, though features like local dimming are not available. The new TVs will also include Internet connectivity for enjoying content from Vudu and others.
Other green features in the LG TVs include an Intelligent Sensor that automatically optimizes the picture to the lighting conditions in the room for potential energy savings. LG says the 55LHX will be available soon, with the SL90 series models available later in the fall.
Sony's 46- ($4,500) and 52-inch ($5,000) XBR10 LED TVs due in October are also edge-lit. The TVs will also have:
But let's face it: edge-lit LEDs can also be cheaper. And edge-lit models could faze out as LED pricing comes down.
