1. A display device, comprising a first display segment and a second display segment connected to each other and foldable towards each other, wherein the display device further comprises at least one magnetic component;
the magnetic component comprises a first magnetic module located in a non-display region of the first display segment and a second magnetic module located in a non-display region of the second display segment;
the display device comprises a first folded state and a second folded state, two opposite ends each of which respectively belongs to the first display segment and the second display segment and faces away from a folding axis are contact ends, the first folded state is a state in which the contact ends come into contact with each other, and the second folded state is a state in which the contact ends have been in contact for a period of time; and
in the first folded state, an attractive force of the first magnetic module to the second magnetic module is A; and in the second folded state, the attractive force of the first magnetic module to the second magnetic module is B, and A<B;
wherein the display device performs a magnetic attraction movement from the first folded state to the second folded state, the first magnetic module comprises a first magnetic body and a first resisting force generation unit the second magnetic module comprises at least a second magnetic body; during the magnetic attraction movement, the second magnetic body provides a first attractive force to the first magnetic body, the first magnetic body provides a second attractive force to the second magnetic body, and the first resisting force generation unit is configured to provide the first magnetic body with a first resisting force opposite to a direction of the first attractive force; and
the first attractive force is larger than the first resisting force.
