UV Light on sister's phone; what's with the blue oval?
UV Light on sister's phone; what's with the blue oval?
Sister was messing around with a UV light and noticed this on her phone screen under it. My phone does not have this (all I get is a grid of dots I'm pretty sure are to do with the touch screen).

Maybe it is the backlight of a LCD panel (and you're not seeing this because of an Oled perhaps), if that's one in the first place... That's the only thing i can think of.
