Greener HD TVs, using Semiconductor-based Light-Emitting diodes (LEDs)

The push to produce green televisions is starting to take off. Samsung, Sony, Vizio, and LG are rolling out TVs that consume less energy. The makers have begun to use semiconductor-based light-emitting diodes (LEDs) as the primary light source for LCD TVs, replacing traditional fluorescent lamps, to cut power consumption by more than 40%. LEDs are also mercury-free, making them more eco-friendly.
