two edges instead of all four. LG claims its latest Full HD 47-inch panel is the "world's most energy efficient," using a single vertical edge backlight to achieve 400 nits of brightness with just 28W of power -- less than any other HDTV bigger than 40-inches and even less than many 20-inch PC monitors. That's all good so long as there's no head-lighting or other tell-tale signs when the panel built into a final product. We hope for LG's sake that the washed out right side on the picture above is due to burning rubber. Full PR after the break.
