Rapoport-Zink formal schemes are moduli spaces of p-divisible groups equipped with additional structures coming from an algebraic group. In order to define these formal schemes in general, one is led to search for the "right" way to endow a p-divisible group with the structure of an arbitrary algebraic group. We discuss a Tannakian approach to this problem using Zink's theory of displays, and we explain how it recovers another approach using crystalline Tate tensors in the Hodge-type case.
