Here's a closeup of the LEDs themselves, which are visible along the strip at the top. Despite their yellowish appearance, each produces white light, which is filtered and sent through the LCD panel. According to Samsung, the advantage of using white LEDs, as opposed to the multicolored "triluminous" LEDs in Sony's XBR8 models, is purer reproduction of color-corrected primary and secondary colors at low luminance levels, as well as better energy efficiency.

Here's where we mention that, unlike so-called local dimming LED based displays we've reviewed in the past, these edge-lit models can't dim or turn off the LEDs selectively. That's why we expect that the black-level performance of edge-lit LED-based LCD displays won't match that of local dimming models, such as the Sony XBR8 or Samsung's own A950 series.

I appreciate the time put in the articles to explain the technology coupled with a picture so as to provide a more "clearer" understanding. Thanks guys.
