White leds promise green illumination domination

But a handful of start-up companies have been plugging away at another display technology that could enhance LCDs and unseat OLEDs: quantum dot s. These light-emitting semiconductor nanocrystals shine pure colors when excited by electric current or light and promise rich, beautiful displays that would be inexpensive and easy to manufacture. Light guides spread the illumination evenly across the panel; the light then passes through a series of optical films that colorize, polarize, and diffuse it. More pure, saturated red, green, and blue yield a wider range, rendering more-lifelike images. The process is also extremely inefficient: More than 90 percent of the light from the white LEDs which are really blue LEDs coated in yellow phosphor is wasted as it passes through the optical film stack.

Saving clients energy, maintenance and money. The big mega trends of recent years will continue of course, as digital disruption will challenge some business models and create opportunities for others, especially those who can make digital experiences a seamless and positive customer experience. The client-specifier-manufacturer-wholesaler-contractor supply chain used to be understood by everybody.

Remember the grungy record-store dude who mocked your music choice before insisting you spend your hard-earned cash on an obscure noise band? Okay, British vinyl vendors aren't exactly jumping on planes to Belgium. But there are some who fear that by consenting this month to a seismic shakeup of the music industry, European legislators could soon have as much impact on what we listen to as a grumpy dude in a Sonic Youth T-shirt. For defenders of the independent music scene, the deal represents an escalation in major label hostilities at a time when revenues are also threatened by piracy and online pricing.
