It almost looks like fungus spreading between the cells. That or the cells leaking in some very strange way.

Before the purchase it was like this

This looks somewhat similar (but worse) and also mentions fungus/mold and liquid damage. As for how to fix it... I think the damage is already done, but I would probably try a warm, dry place (something like a food dehydrator? set to something like the CPU's operating temperature) to dry out whatever's in there and at least stop it from spreading any further.

In the very first photo, is the screen on or off? Because if it looks like this even without a backlight then god damn!

Turned off in this photo 🙁

It reminds me of Vinegar Syndrome, and indeed the page is illustrated with an image of a laptop with a heavily degraded screen. In your first photo in the bottom right corner, are those bubbles or just marks on the screen?

I wanted to see the early stages of VS but turns out it's surprisingly hard to find other images of it at all. Here's some of photo, not LCD, material at least. (edit: here's something that looks somewhat similar, but I'd still call that look "tension lines" rather than "fungus".) I don't think this is it exactly - OP's intricate patterns just don't look a lot like VS's blobs - but you may be on to something wrt something eating away at the polarizer. Which appears to be fixable, but it certainly wouldn't be the first thing I tried doing.

Looks like people are calling this LCD rot...I haven't seen any explanation as to what causes it but do some image searches on that and you can see similar issues. My guess is the guy didn't send you the unit that he pictured, I doubt this was from shipping damage.

If it is indeed Vinegar Syndrome, not al is lost, although the repair is challanging. The repair needs the replacement of the lcd polarizer which can be done. The key challanges are:
- Disassambly of the screen without breaking anything
- removing the (glued on) polarizer without force or damaging the actual screen
- adding a new polarizer, if possible in a zero dust environment, and without any bubbles
- putting everything back together.

Best to practice first with an old gameboy

This is what it takes to fix it in a modern display:

I also agree its very unlikely this just showed up in transit.

I'd compare the unit you have to the unit in the pictures before purchase. Look out for scratches or so that one has but the other doesn't.

For example these scratches in the *previous* pictures I circled. If these are also at the same spot as on the actual device, you know at least that it is likely to be the same one.

Hello, I will let you know when I find time, I think for the weekend

Hello everyone, not happy 🙁

Unfortunately, I have to look for such a matrix.

I am sad
Thank you for help.

Photo glass matrix

🙁

Other than try to find a solution to fix the issue, you should follow the Dominus suggestion.

Its already bad so no harm opening up the display module and looking between the layers. 2 screws and 8 metal tabs to unbend and you are in. Be gentle to not rip off very delicate flex bonded to the glass, and try to do it in a cleanest room in the house, away from pet hair 😀

I just share a repair attempt that went 85% ok. This is a early Vaio sub-notebook which had serious vinegar disease. I managed to install new polarizers, but you can see 2 spots on the screen where some tiny dust flakes remained causing small bubbles on the display - but otherwise it worked ok. If you are really thinking about repairing - the gameboy suggestion is actually a really good idea. Vinegar disease Gameboys are aound in vast numbers and you learn all the critical steps on a very cheap screen.

Looks like when Fungus grows inside old camera lenses.

There is no foil there
