I replaced my Ledger Nano S screen around one year ago now. Still working perfectly fine after one year and I used it a lot lately! I am very happy with it. Very easy to replace (I know nothing about electronics), you can find several videos to help just searching for something like "ledger nano s screen replacement". I ordered the screen online but not on a Chinese website, on another website that only sell Ledger Screens. A bit less cheap but still a very good price, good shipment tracking and support in English (tested before order).
Unfortunately mine was not under warranty anymore. But I was able to change the screen for a few bucks, very easy by following this video https://youtu.be/zZyHwA2lkwM
