Edge-Lit LED Backlighting Moving to Samsung TVs

A new product is slated to come out of the Samsung labs and into the market soon. Samsung is reportedly beginning the mass production of its new HDTV; the kind that's so thin, it can be hung on the wall like a painting. The difference between this new product and the usual ultra-thin HDTVs? Energy consumption.

Samsung's lightweight super-thin TV utilizes a technology that allows it to consume up to 40 percent less what a conventional TV of the same size and capacity consumes. The savings in energy are due to its LED backlighting. But while it's natural to think the LED lights themselves save energy, there's actually one more factor that contributes to its efficiency - the LED lighting's placement on the LCD.

Samsung's new HDTV uses edge-lit LED backlighting that places LED lights in rows on the top and the bottom of the panel.

In this position, the light is directed or focused towards the center of the screen for better picture quality and lesser energy use. The LEDs used for the backlighting are, of course, mercury-free as well. "There is a rising demand for light weight large TVs that can be mounted on the wall like a painting, with LED backlighting as a higher quality alternative to the more common CCFL (cold cathode fluorescent lamp) technology," said W. K. Chang, president of Samsung Electronics LCD Division.

Samsung's new HDTV will come in 40-inch, 46-inch and 55-inch diagonal size models when they are released to the public.
