It really is very transparent! I guess technically translucent but its very good!
That horizontal line in the bottom of the screen I think is an adhesive bonding the layers together?? On a standard OLED this doesn’t matter because you can’t see it but…
It appears to be in the active matrix layer. The screen is oddly sold as 56 vertical pixels… is it actually 64 pixels, but the last 8 are obscured by the glue? That’s my guess.
This is pretty weird, I would assume there are bonding agents that could be used that are transparent. That idicates to me these screens exist for a specific customer that requested to take the black layer out of the OLED, changing the glue would have required a lot of investment in R&D to figure out what would work in manufacturing process, and if it’s something new they would have to test it in large batches before they knew the yield of a unproven process.
So the customer probably just decided, that’s ok we can block out the bottom 8 pixel area with a shroud.
I am very curious what the application for these are. HUD makes some kind of sense, but I think it would be too close to your face to be viewable? I mean, that’s probably what I’m going to make out of it because the #internet demands it.
