Details are about as light as can be on this one, but it looks like Japan's Ito Electronics has developed some sort of special "packaging technology" that can make OLED displays fully waterproof, which could be particularly used for watches, cellphones, or that fish tank home theater you've always dreamed of. Of course, there's no word on any actual products just yet, nor is there any indication of possible transparent waterproof displays -- or, at least, none that anyone has seen.
