1. A foldable display device, comprising:

  • a first housing and a second housing which is hinged to the first housing with a first shaft;

    wherein the first housing has a first closed surface and the second housing has a second closed surface; and

    the first housing and the second housing is capable of rotating about the first shaft to be open or closed; and

    a touch screen covering the first closed surface and the second closed surface;

    wherein the touch screen has a bendable region corresponding to a connection region for the first housing and the second housing;

    the bendable region presents a planar structure when the first housing and the second housing are open and presents a smooth curved structure when the first housing and the second housing are closed;

    wherein a first groove is defined in an end of the first housing neighboring the second housing, a second groove is defined in an end of the second housing neighboring the first housing, and the first groove and the second groove are aligned and joint to define an accommodation space for accommodating the bendable region;

    wherein the foldable display device further comprises;

    a first barrier plate in the first groove; and

    a first movement structure configured to control movement of the first barrier plate between a first position and a second position;

    wherein the first barrier plate is at the first position where an opening of the first groove is and the first barrier plate is in a same plane as the first closed surface, when the first housing and the second housing are open; and

    wherein the first barrier plate is at the second position when the first housing and the second housing are closed, the second position is in a second portion other than a first portion in the first groove, and the first portion in the first groove is configured to accommodate the bendable region;

    wherein the first movement structure comprises;

    a second shaft at the opening of the first groove and at an end of the opening away from the first shaft wherein a first end of the first barrier plate is hinged on the second shaft; and

    a first transmission structure with one end connected with the first shaft and an opposite end connected with a second end of the first barrier plate;

    wherein driven by the first transmission structure, the first barrier plate rotates with the first shaft so as to move between the first position and the second position;

    wherein the first transmission structure comprises;

    a first positioning post on an outer peripheral surface of the first shaft anda first connection line with one end connected with the first positioning post and an opposite end connected with the second end of the first barrier plate.
