OCA is applied from edge to edge. If it was the adhesive, the whole screen would be lighting up. Also, OCA is cured with UV light, but it doesn’t fluoresce.
Well I don't want to paste another Gemini response as Lemmy seems to hate it so (and I do too when someone is pretending like the text their showing is isn't LLM created, when it is.)
Anyway I rephrased the question and added your info to it. It suggests the shape might be due to a polariser film, but I don't agree with that as it too would fill the whole screen.
Gemini points out that it might be another part of the screen stack. Which I wouldn't agree with. When you buy a replacement "screen", you're actually buying a stack of components and maybe one of those assembly processed uses a UV-fluorescent glue or component.
Who knows imagine a shruggie here im too lazy to copy one and then get the formatting right so it shows up properly even though I now realise it would've been faster to do that than write this sentence
Yeah the real issue for me is that in addition to not filling the screen, it’s also asymmetrical. So it can’t be something done on purpose.
Well if it was originally liquid and gets squeezed in between two thin parts during machine assembly, I could see it developing to be that shape.
That’s a good point. I don’t think it can be an adhesive, but maybe some other kind of layer?
Still odd that it’s fluorescent. If it’s that close to the front-facing camera (and meant to be spread over it), it would ruin any photo taken outside during the day.
