Printable OLED panels are hardly the rare occurrence they once were, but Alps Electric seems to think it's worked enough magic with its latest prototype to stand out from the pack, even if it may not wind up in actual product form anytime soon. The key bit with this one, it seems, is a so-called "getter" layer that's used in addition to the usual electrodes and emission layer, which helps to seal the area around the cathode electrode and compensate for minute defects. According to the company, that effectively triples the life of the OLED panel, which is especially useful considering that the same technology is also increasingly being used for lighting systems in addition to displays.
