Title: FOLDABLE DISPLAY DEVICE
Abstract:
The present invention relates to the field of display devices. Provided is a foldable display device (00) comprising a supporting plate (10) and a flexible display screen (20) provided at the supporting plate (10). The supporting plate (10) comprises at least two sub-supporting plates (101) and at least one position-limiting structure (102). The position-limiting structure (102) is used to connect target side surfaces of adjacent sub-supporting plates (101). The target side surfaces are not parallel to a display surface of the flexible display screen (20). The position-limiting structure (102) comprises at least two inwardly-bent position-limiting structures (1022) and a first flexible band (1021) used to connect adjacent inwardly-bent position-limiting structures (1022). When the flexible display screen (20) is bent to a preset angle in a direction away from the supporting plate (10), the at least two inwardly-bent position-limiting structures (1022) can limit relative positions of the adjacent sub-supporting plates (101). The present invention employs at least two inwardly-bent position-limiting structures (1022) to perform a position-limiting operation so as to reduce occurrence of damage to a flexible display screen (20), thereby solving a problem in the prior art in which when a flexible display screen (20) is inwardly bent to an excessively large angle, such excessive bending is likely to cause damage to the flexible display screen (20).
