New things are coming out all the time (like this <A href="http://www.treehugger.com/files/2008/07/led-lights-technology-breakthrough-purdue-university.php">big LED breakthrough from Purdue</A> and <A href="http://www.treehugger.com/files/2008/07/lcd-competition-microsoft-research-telescopic-pixels-screen-display.php">telescopic pixel screens</A>), but we get used to them so fast that we're always looking ahead and it never seems to get there fast enough. It was only a few months ago that we wrote about a big organic light-emitting diode (OLED) breakthrough by Osram who had succeeded in making <A href="http://www.treehugger.com/files/2008/03/osram-warm-white-organic-led-oled.php">OLEDs that produced 46 lumens per watt</A>. </P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.treehugger.com/"><P><STRONG>Better OLEDs!</STRONG>
Now researchers at the U. of Michigan and Princeton are saying they made OLEDs that can produce 70 lumens per watt (compared to 15 lumens per watt for incandescent), and that they might be able to do even better than that. To achieve that impressive efficiency, they are using a grid combined with micro-lenses, all of it on the nano-scale (the lenses are 5 micrometers wide). </P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/CEE509BE-EB5B-47B6-ACB6-3CAC33B8FE7B/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
