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).

All glowing unknowns under a UV light are considered Cum unless proven otherwise

Their sister's cum.

is making sure the internal Cum is perfectly shaped a desirable job at the factory, i wonder?

[–] jewbacca117@lemmy.world 9 points 1 week ago

The real desirable job is the guy who gets to cum in phones

[–] JustZ@lemmy.world 6 points 1 week ago

That's just from setting the glass. Totally natural phenomenon.

[–] Frozengyro@lemmy.world 2 points 1 week ago

Depends, are you at the phone factory or the cum factory?

"Oh man, it glows?"

Not sure what it might be but shape and position match those of the wireless charging coil.

[–] Melonpoly@lemmy.world 34 points 1 week ago (2 children)

That wouldn't be behind the screen nor rectangular

[–] pearsaltchocolatebar 22 points 1 week ago (1 children)

Charging coils can absolutely be rectangular.

[–] ColeSloth@discuss.tchncs.de 8 points 1 week ago

They can't be behind the battery, though, so this can't be it.

They also can't be that long and still work with any efficiency.

[–] mrfriki@lemmy.world 10 points 1 week ago (1 children)

Oh, I thought that OP was asking for the circular shape, the rectangular one looks more like some short of graphic showing on the screen. But maybe the circle is just the reflection of the flashlight?

[–] Joeffect@lemmy.world 4 points 1 week ago

Yes, the circle is light from a light source...

[–] Sir_Kevin@lemmy.dbzer0.com 14 points 1 week ago

Wouldn't that be on the back side of the phone though? I suspect the battery would be between the coil and the display, making it impossible to see from this side under any kind of light.

That said, I donno WTF we're seeing.

Pretty sure it was Mrfriki's guess.

[–] poplargrove@lemmy.world 1 points 1 week ago

They might have posted first but ShepherdsPie actually realized it first. I was there.

[–] SatansMaggotyCumFart@lemmy.world 44 points 1 week ago (1 children)

Might be the glue holding it in place.

[–] ch00f@lemmy.world 18 points 1 week ago

OCA (optically clear adhesive) is spread as a thin layer between the digitizer and display. Any gaps would be easily visible with the naked eye.

Also, it’s cured with UV, but I’ve never seen it fluoresce.

What model phone, it might be the fingerprint sensor?

[–] ColeSloth@discuss.tchncs.de 7 points 1 week ago

What I wondered, but double checked pixel 8 and 8 pro specs and it just has a normal sensor area towards the bottom of the screen.

Does she have a screen protector? Can you see the shape at all without uv light? My guess would be an air bubble under a screen protector, but that would be visible under normal condition, sometimes it could be hard to see.

[–] BartrandDuGuesclin@lemmy.world 8 points 1 week ago* (last edited 1 week ago) (1 children)

Backlight LCD screen perhaps? And if you have an Oled screen, that might be why you're not seeing this on yours? I don't know for sure tho...

[–] Kolanaki@yiffit.net 8 points 1 week ago (1 children)

I have a Pixel 8, and the one in the picture is an 8a/8pro (can't remember which).

I think all Pixels have Oled, so i guess i'm wrong here... It is interesting for sure!

[–] BlastboomStrice@mander.xyz 2 points 1 week ago

Here's mine (Xiaomi Mi 10):

It has no screen-protector. It does not emit blue light from the glass edges. In the center I think it's slightly bluer than the rest of the screen. It is an amoled screen. Hope this helps somehow.

I dont know if they stick the glass with uv glue, they tend to do that with screen protectors for screens with curved edges, so that the protectors sticks better. Maybe it's the glue reacting.
