Samsung edge-lit LED-based LCD; LED lighting assembly

Here's a closer look at the assembly. The rightmost, thinner three panels are the color filter, polarizing filter, and diffuser. The leftmost, notched white panel is the reflecting back, the only one of the five elements that sits behind the row of LEDs (top).

Second from the left is the clear-looking, thicker "light guide," a proprietary Samsung development that uses a series of tiny lens-like refractors to send light from the LEDs along edges toward the middle of the screen. The company claims its edge-lit LED-based LCDs have the same uniformity characteristics as its standard backlit LCD displays. If true, that would be an improvement on the only other edge-lit display we've reviewed so far, the Sony KLV-40ZX1M.
