1. A display device, comprising:
a first rotating component, the first rotating component being capable of rotating about a first center line;
a second rotating component, the second rotating component being capable of rotating about a second center line;
a flexible display panel, the flexible display panel being capable of being wound around the first rotating component, and a first end of the flexible display panel being configured to move to a position away from the first rotating component from a position close to the first rotating component or to move to a position close to the first rotating component from a position away from the first rotating component under an action of an external force;
a supporting part, the supporting part being capable of being wound around the second rotating component, and a first end of the supporting part being configured to move to a position away from the second rotating component from a position close to the second rotating component or to move to a position close to the second rotating component from a position away from the second rotating component under the action of the external force;
wherein the flexible display panel and the supporting part have a laminated portion in mutual lamination, and the laminated portion is configured to increase or decrease under the action of the external force,
wherein the flexible display panel includes a back film, the back film is located on a non-display side of the flexible display panel, and the non-display side and a display side of the flexible display panel are opposite to each other; the back film is in contact with the supporting part,
wherein the back film includes a magnetic material; the supporting part includes a magnetic material; the back film and the supporting part are capable of being laminated to each other under an action of an attraction force,
wherein the back film includes a magnetic material pattern,
wherein the magnetic material pattern includes a plurality of magnetic stripes parallel to each other,
wherein the plurality of magnetic stripes are arranged along a first direction, each of the plurality of magnetic stripes extends along a second direction; or, each of the plurality of magnetic stripes extends along the first direction, the plurality of magnetic stripes are arranged along the second direction, and the first direction intersects with the second direction,
the supporting part includes two supporting pieces extending along the first direction and a plurality of connecting pieces connecting the two supporting pieces, and the supporting part includes a plurality of opening regions between the two supporting pieces and the plurality of connecting pieces, and
the supporting part is configured to attract the magnetic strips in the back film.
