Thin polymer to extend OLED display life?

A polymer discovered at Georgia Tech could allow air-stable electrodes to be used in OLED displays.

At the moment, efficient OLED displays need to have low 'work function' metals as internal electrodes, which are all reactive metals like calcium, magnesium or lithium that are corroded by air.

It is partly for the protection of these electrodes that there is so much research into barrier layers to keep oxygen and water out of flexible OLED displays.
