The Item and Stand display, are machines, that are mostly for be used in shops. They do what their name says, one is used to display items, and other to display armor sands.
To display an item, you just have to put it in the center slot of its inventory, then a visual version of that item will appear floating above it. If the item has a custom name, that name will render above the item.
Please note that no other slot will work, they have no function, at least for now.
The stand display is more tricky to use them you have to configure each slot accordingly. You can also use a name tag to name the armor stand, or use a book and quill to apply changes to its pose (see Armor Stand Controller).
WARNING: Do not attempt to equip a Display Stand, it should not work, but if for some reason it does you will lose your items.
