The theory of displays is a Dieudonné theory for formal pp-divisible groups which is an equivalence of categories over an arbitrary pp-adic ring. Over a more restricted class of rings one obtains a classification of all pp-divisible groups. We explain basic ideas and some recent results of this theory. The last paragraph ameliorates the discussion of isogenies of displays found in the literature.
