It can be appreciated that there may be a plurality of second positions, and in each second position, the lengths of the functional elements 30 protruding from the main display area 10 may be different, so that the main display area 10 is at different angles with respect to the supporting surface, thereby meeting different use requirements of users.
It should be noted that, in some alternative embodiments, the foldable display screen provided in the embodiments of the present application may include a flexible display panel, where the main display area 10 and the auxiliary display area 20 are both part of the flexible display panel, and a bending area may be disposed between the main display area 10 and the auxiliary display area 20. In other alternative embodiments, the main display area 10 and the auxiliary display area 20 may be rigid display panels, and the foldable display screen may be formed by splicing a plurality of rigid display panels; alternatively, adjacent rigid display panels may be connected by a flexible display panel to achieve a full screen display.
Fig. 15 is a schematic structural diagram of a display device according to an embodiment of the present application.
In addition, the embodiment of the application also provides a display device which comprises the foldable display screen.
The display device provided in this embodiment of the present application may further include a casing 60, where the casing 60 includes a support casing 61, and the support casing 61 is disposed on one-to-one with the main display area 10 and the auxiliary display area 20, and two adjacent support casings 61 are rotationally connected with each other. The support housing 61 is provided to protect the main display area 10 and the sub display area 20 of the foldable display screen and to facilitate folding of the foldable display screen.
It will be appreciated that when the foldable display screen includes a flexible display panel, the main display area 10 and the sub display area 20 of the flexible display panel can be supported by the support housing 61.
Alternatively, the functional element 30 may be connected to the casing 60, which is simple and convenient.
