Flexible Display Supporting Structure with Rotatable Plates

The supporting structure is divided into multiple supporting plates (first supporting plate, second supporting plate, etc.) that can move independently. Each supporting plate provides localized support to different regions of the flexible display panel, ensuring stable support across the entire display area during unfolding while maintaining the ability to expand the display area.

The supporting plates are designed with dynamic characteristics, allowing them to rotate and move relative to each other. In the unfolded state, the supporting plates maintain fixed positions to provide stable support. In the rolled state, the supporting plates can rotate around rotation axes, enabling the entire structure to be compacted into a small volume. This dynamic design resolves the contradiction between rigidity for support and flexibility for compact storage.

Rotation axes serve as intermediary elements between adjacent supporting plates. These rotation axes allow controlled relative rotation during the rolling process while maintaining structural integrity. The rotation axes are positioned and designed such that they enable compact rolling but prevent unwanted rotation in the unfolded state, thus mediating between the requirements for compact storage and operational stability.

The supporting structure is designed to automatically lock and unlock based on its state. In the unfolded state, the relative positions of the supporting plates naturally engage locking features that prevent rotation without requiring external actuation. In the rolled state, the movement of the supporting plates automatically disengages the locking features, allowing rotation. This self-service locking mechanism provides stability when needed without significantly increasing device complexity.
