I bought this screen from eBay - https://www.ebay.com/itm/183565808942
But I can't seem to connect the cable to the controller board.
How does one connect/disconnect this type of cable?

Do you mean the connector sticking out of the screen?
It's a flexible printed circuit (FPC), also known as flexible flat cable (FFC).
Usually the connector on the board will have a locking mechanism. There's a part of the connector with either slides back or up or rotates up. Then you insert the connector, and push back the moving part until it clicks back in place.
This picture from Omron gives a couple of examples:
As you can see, there are different types of connectors with the moving part in different places (there are more), so you'll have to get a look at the connector to find out what moves and how.
