1. A stretchable display module, comprising: a display panel, a magnetic field generator disposed on at least one side of the display panel, and a feedback regulation unit electrically connected to the display panel,
wherein the display panel has a stretchable region and comprises at least one stretchable closed loop circuit surrounding at least a portion of the stretchable region;
the magnetic field generator at least covers the stretchable region and is used for generating a magnetic field at least covering the stretchable region and perpendicular to a display surface of the display panel; and
the feedback regulation unit is electrically connected to the at least one stretchable closed loop circuit, is used for acquiring an induced electromotive force, generated by the at least one stretchable closed loop circuit under an action of the magnetic field, in real time in a stretching process of the stretchable display module, and regulates a stretch state of the stretchable display module according to a magnitude of the induced electromotive force.
