Claim 18:
19. A flexible display device, comprising:
a rolling assembly;
a flexible display module at least partially wound in the rolling assembly; and
a housing comprising an accommodating chamber in which the rolling assembly is rollably disposed,
wherein the rolling assembly comprises a shaft and at least a shell layer coaxially arranged from an inside to an outside of the rolling assembly, the shaft and the at least a shell layer are coupled to each other and collectively allow for formation of a cross-sectional curve based on a characteristic of an Archimedes spiral, and the flexible display module comprises a first end fixedly connected to the shaft;
wherein the flexible display module is configured to drive the rolling assembly to rotate in a direction of releasing the flexible display module from a retracted state along with a process of expanding the flexible display module, enabling a linked state of the shell layer and the shaft to be released;
wherein the rolling assembly is configured to rotate in a direction of retracting the flexible display module along with a process of retracting the flexible display module, enabling the shell layer and the shaft to return to the linked state;
wherein the housing is provided with an opening communicating with the accommodating chamber, the flexible display module further comprises a second end extending from the opening into the accommodating chamber to be fixedly connected to the shaft, and the first end of the flexible display module is located outside the housing; and
wherein an inner side wall of the housing is provided with a slide rail corresponding to the shaft and the shell layer, the shaft and the shell layer are slidable along the slide rail, and the slide rail is configured with a trajectory curve coinciding with the cross-sectional curve of the shaft and the shell layer.
