I've personally seen transparent OLED displays in museum displays. So the market is definitely closer to that of video walls, than of 85-inch televisions made for the living room. I could see it coming to controlled conditions like supermarket freezer window panes, but not something architectural. Sure, the signage business might not be high volume relative to consumer electronics. However, engineering entire new use-cases to target larger markets might not be worthwhile, if supply and pricing cannot meet market expectations due to yield constraints.
