18. A display device, comprising:
a foldable device; and
a display panel;
wherein the foldable device comprises:
a frame plate;
one primary folding axis;
at least one secondary folding axis, wherein the at least one secondary folding axis intersects the primary folding axis to divide the frame plate into a plurality of sub-frame plates; and
a folding mechanism including a first folding hinge and a second folding hinge;
wherein at least one pair of adjacent sub-frame plates located on the primary folding axis are connected by the first folding hinge, at least one pair of adjacent sub-frame plates located on the at least one secondary folding axis are connected by the second folding hinge, and any one of the sub-frame plates is connected to at least one of the first folding hinge or the second folding hinge;
wherein the display panel is disposed on a side of the frame plate of the foldable device;
wherein each of the first folding hinge and the second folding hinge comprises:
a first rotating member;
a second rotating member; and
a first base, wherein an end of the first rotating member is rotatably connected to the first base, and an end of the second rotating member is rotatably connected to the first base;
wherein a side of another end of the first rotating member of the first folding hinge is connected to one of the at least one pair of adjacent sub-frame plates located on the primary folding axis, and a side of another end of the second rotating member of the first folding hinge is connected to another of the at least one pair of adjacent sub-frame plates located on the primary folding axis;
wherein a side of another end of the first rotating member of the second folding hinge is connected to one of the at least one pair of adjacent sub-frame plates located on the at least one secondary folding axis, and a side of another end of the second rotating member of the second folding hinge is connected to another of the at least one pair of adjacent sub-frame plates located on the at least one secondary folding axis;
wherein the folding mechanism further comprises:
a hinge structure including a third rotating member, a fourth rotating member, and a second base, wherein an end of the third rotating member is rotatably connected to the second base, and an end of the fourth rotating member is rotatably connected to the second base;
wherein the at least one pair of adjacent sub-frame plates located on the primary folding axis are connected by a first hinge structure,
wherein a side of another end of the third rotating member of the first hinge structure is connected to one of the at least one pair of adjacent sub-frame plates located on the primary folding axis, and a side of another end of the fourth rotating member of the first hinge structure is connected to another of the at least one pair of adjacent sub-frame plates located on the primary folding axis.
