LEDs into gold: Can it be done?

LED-backlit LCD TVs, enabled by Dolby Laboratories' High Dynamic Range (HDR) technology, produce stunning pictures. Unclear, though, is how much consumers will have to pay for that kind of picture quality. "These products have been screaming to get out to a mass market," said Eric Haruki, research director for TV markets and technologies at IDC. But he cautioned that unless LED manufacturers can achieve the economies of scale and cut the cost of LEDs, "this could still remain a great white hope for awhile."
