I first checked which panels were the good ones here: https://www.notebookcheck.net/Lenovo-s-Panel-Lottery-continu..., which indicates Innolux is the panel to get. Then I went to https://support.lenovo.com/ie/en/partslookup and punched in my serial number, located near the bar code on the bottom of the laptop. From the "Parts" tab select the "Commodity Type" as "LCD PANELS" and you should see something like "FRUofAUO14.0FHDIPSAG" indicating I get the "AUO" manufactured LCD panel. If you are particular about getting the Innolux, you can use the substitutes button to figure out the lenovo replacement part number for the desired LCD Panel. For the Innolux on the T14s, it could be ordered here: https://lenovo.encompass.com/item/12401836/Lenovo/01YN156/, but it seems to be currently out of stock.
