Roll to roll printing of OLEDs by General Electric

March 13, 2008 / No Comments

General Electric has been working for the last four years to get their project involving roll-to-roll printing (like a newspaper) of OLEDs, live. The newly printed Organic Light Emitting Diodes are extremely energy efficient, with high performances and are supposed to be pretty cheap. I already have a few ideas of using the prints from extremely big sizes to very weird designs.

Because this had never been done before, we faced some real technical challenges – especially given our program time constraints that often meant we had to start designing machine modules before we had the device fabrication process completely figured out! Anyway, in the end it all came together and we were successful in making our deliverable” said Anil Dugall on the GE Global Research blog.

OLEDs (organic light emitting diodes) are a type of LEDs, made of thin films of organic molecules. They are supposed to be a common thing in the green gadgets of tomorrow with the main advantages being: no need for a backlight to function, they draw less energy and are thinner than LCDs.
