We have more than 2,700 patents issued and pending. We actually just purchased 1,255 patents from Fujifilm and the OLED field and I’ll talk a little bit more about that as I move forward. And we have fundamental intellectual property in the architecture of making an OLED using our phosphorescent and in the actual materials that we make and sell. We have that made for us by PPG Industries. We’d always qualify them and shift them from our facility in Ewing, New Jersey.
This is a what an OLED architecture looks like, just to give you an idea, as LCD technology, which is on this laptop and a number of others if you actually pulled it apart you would see a bright white light in the back then you see a piece of glass that has transistors and on top of that you put layers of liquid crystals and if you pushed on your screen you would actually see them move around.
OLED is very different, there is no backlight. These are self emissive materials. You have your transistor play and then you put about 7 to 9 layers of film on that transistor play and then you put glass on top of that. That’s the entire device, there is no light bulbs, it’s not reflective, it doesn’t use ambient light, but the materials themselves lied up. This entire stack is 1,100 to thickness of a hair.
