The greatest challenge to using daylight as a
primary light source is that it is naturally dynamic.
Using LEDs as its
primary light source, the 3D LED televisions all feature ultra-high contrast ratios as well as slim depths that allow for more artful designs, plus increased energy savings.The 3D LED TVs come with the ability to stream content using AllShare and Internet@TV.
Each using LEDs as their
