Yesterday I posted about UCLA's new EPLED device, a highly-flexible elastic polymer light emitting device. At first I thought it was an OLED (they state so several times in the UCLA press release). But it turns out that it is actually a LEC device (a polymer LEC, or PLEC) and not an OLED.

The researchers explain that they chose P-LEC (polymer-LEC) device architecture and not OLED because it's simpler, there's no need for specific electrode work functions for charge injection and it has a straightforward fabrication process, compatible with conventional polymer processing technique.

In 2012 we posted an article introducing LEC and PEC technologies and explaining how they compare to OLEDs.

Thanks for the tip, Martin!
