1. A stretchable display substrate, comprising:
a base substrate, a plurality of opening patterns being distributed on the base substrate, a plurality of bridges being formed between adjacent ones of at least a part of opening patterns in the plurality of opening patterns to define islands;
a plurality of display units, at least one display unit being arranged on each island;
a plurality of wiring units each coupled between the display units on the islands and arranged on the bridge; and
a thin film encapsulation layer comprising a first encapsulation portion covering a side of each display unit away from the base substrate and a second encapsulation portion at least covering a side of each display unit adjacent to the opening pattern, the second encapsulation portion being used to protect a side of the display unit adjacent to the opening pattern,
wherein each of at least a part of opening patterns has different opening sizes at a side of the base substrate adjacent to the display unit and a side of the base substrate away from the display unit, the opening pattern has at least one step-like structure at a side adjacent to the island, and the thin film encapsulation layer is interrupted at the step-like structure.
