You need to buy exact display model that ledger is using so it's best to copy exact name and search online and offline in your local shops.

All you need is to use this phrases when you search to buy display:
0.91"128x32 OLED Display with Connector FPC, SSD1306, ER-OLED0.91-3W

One that you posted looks very similar but connector may be different.
Following this video instructions I see that he used Display with 12 PINS and there is direct link on Taobao website for that.
Display is probably the same on all websites but cable connections can have different number of pins.
