Why aren't there more glow in the dark keyboards for a more passive form of keyboard backlighting?
Is it because the glow would fade after a year or two? Even if it's not cost effective compared to adding to LEDs I thought it would be a novelty thing.
I did a quick search online and it doesn't seem very common. Mostly keyboard covers.
Of course on both accounts. I imagine it would gradually fade out over the course of around an hour or so.
I mentioned it in my post and another comment but I thought it would have been an occasional novelty you would see online. Maybe in an weird Ali Express device.
