" Fully Screen Printed Light Emitting Polymer Displays"

The discovery of semiconducting polymers in the 1970's
offered the promise of using liquid-based processing to
make fully printable semiconductor electronics that would dramatically cut costs over traditional solid state high temperature vacuum-based processing. Several decades later, many printing techniques, such as ink-jet, reel-to- reel, slot coating and screen printing, have been shown to be useful for printing part of the semiconductor device structure. Nonetheless, the initial promise of fully printable commercially-viable semiconductor polymer devices has yet to be realized due to several key marketing, manufacturing and technical challenges.

In this talk, I will discuss how we have overcome some of
these challenges to make the first fully printed light
emitting polymer display using a screen printing process. Starting with a blanket deposited ITO coated plastic (or
glass) substrate, we have developed a manufacturable
process that allows all the layers in a light emitting
polymer display to be patterned and printed using a
standard screen printing press operating under atmospheric
conditions. I will address the technical issues associated
with screen printing an electroluminescent polymer layer
and the top electrode (cathode) to maximize device
performance. The advantages and disadvantages of screen printing over alternative printing technologies, such as ink-jet and reel-to-reel, will be compared within the context of the commercial applications. I will end by showing demonstrations of fully printed polymer devices and discuss the applicability of this manufacturing technique to other polymer electronic devices, such as solar cells.
