Advancements in LED technololgy.
Found another interesting tech article.
This ones about a recent advancement in LED's. While this has more relevence for larger LED applications, I'm sure the benefits and options sure will eventually trickle down to our beloved smartphones.
Now one of the world's largest LED makers, Osram Opto Semiconductors, says it has perfected a technique that could significantly cut the production cost of LEDs.
The company says its silicon-based white LEDs produce 127 lumens for each watt of power, with a power efficiency of 58 percent, comparable to state-of-the-art commercial LEDs grown on sapphire.
Last month, California startup Bridgelux announced that it has teamed up with Toshiba to make LEDs on silicon.
Osram has not said how much cheaper its new LEDs will be, but Bridgelux and Plessey both claim that the silicon approach could cut LED production costs by 75 percent or more. Bridgelux also predicts that its process could bring the cost of a 75-watt equivalent LED lightbulb, which now costs $40, down to under $5.
