Although we've been hearing about transparent OLEDs for years now, mum's been the word on an actual product. So far the focus has been on Germany, but it looks like some interesting things have been going down in Korea as well. Researchers at ETRI (the flexible OLED folks) have apparently applied for 51 patents both nationally and internationally for the tech, including one for a transparent oxide resistor that helps increase the aperture ratio of AMOLEDs. And while all this is going down, NeoView KOLON has unveiled a new prototype rearview mirror that utilizes a transparent OLED display for -- well, displaying things. Just be sure to keep your eyes on the road, eh?
