As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
referring to fig. 3 and 4, fig. 3 is a schematic structural view of a flexible display screen provided in an embodiment of the present disclosure when being unfolded, and fig. 4 is a schematic structural view of the flexible display screen provided in an embodiment of the present disclosure when being folded, where the flexible display screen includes a display panel 31, a reel assembly 32, and a folding assembly 33, in this embodiment,
The display panel 31 includes opposite ends;
in particular, the display panel is a flexible display panel. For convenience of subsequent description, in the present embodiment, the two opposite ends of the display panel 31 are described as an a side and a b side, as shown in fig. 3 or fig. 4, where the scroll assembly 32 is disposed at the b side, in some application scenarios of the flexible display screen, for example, when the flexible display screen is applied to an intelligent terminal device, a function key (e.g., a home key of a mobile terminal), a camera, and the like may be set at the a side, and in some embodiments, more function modules, such as a return key, a enter key, and the like, may be set on the flexible display screen according to different application scenarios of the flexible display screen.
In fig. 3 and 4, the heights of the sides a and b with respect to the panel are illustrated only by way of identification, and the height is not particularly limited in this embodiment.
A reel assembly 32, the reel assembly 32 being disposed at one end of the display panel, and being configured to be wound and unwound around the reel assembly 32 at one end of the reel assembly;
In this embodiment, increase reel subassembly in flexible display screen, flexible display screen's display panel can roll up and expand based on this reel subassembly to solve the flexible display screen that the correlation technique provided and fold the material loss that leads to and reduce scheduling problem because of folding the display area who causes at fixed position, its theory of realization is:
When the flexible display screen is completely unfolded, a part of the display panel is kept to be rolled up and protected on the reel assembly, the part of the display panel rolled up and protected by the reel assembly is not displayed, the reel assembly is locked at the moment, and the flexible display screen is displayed in a full screen mode; when the flexible display screen starts to be folded, the reel component cancels locking and releases the display panel part protected by being rolled, wherein the area of the released display panel part protected by being rolled can be equal to the area of the bent part of the display panel when the flexible display screen is folded, so that the area of the display area of the flexible display screen reduced due to folding is compensated, the size of a single-sided display after being folded is improved, and the use experience of a user is improved;
further, because the folding degree or the set folding display area is different, the area of the released part of the display panel which is protected by rolling is relatively not fixed, and the display panel is not fixed in a certain part of the display panel at the bending part of the folding position of the folding assembly in the process of rolling and unfolding.
It should be noted that the display area of the flexible display screen in this embodiment may be flexibly set, specifically, a user sets an area of a portion of the display panel that is rolled in the reel assembly according to a personal requirement, where in order to avoid that the area of the rolled portion is too small to compensate for the reduction of the display area caused by folding, in this embodiment, the area of the portion of the display panel that is rolled and protected is set to be the smallest area that cannot be smaller than the area of the bending portion of the display panel that is folded based on the folding assembly.
In some embodiments, the locking and unlocking scheme of the reel assembly may be implemented by providing mutually matched winding fixing portions at the reel and two side edges of the winding direction of the display panel, specifically, the winding fixing portions wind and fix the display panel when the reel assembly is wound, so that the reel assembly winds and protects a part of the display panel, and when the reel is unwound, the mutually matched winding fixing portions are separated, and so that the part of the display panel subjected to winding protection is unwound along the reel assembly.

in some embodiments, the support structure may be one of, or a combination of at least two of, foam, a graphite layer, and a copper foil. In the flexible display screen, usually, foam, a graphite layer, a copper foil, and the like are attached to the back surface of the display panel, and mainly play a role in supporting and dissipating heat.
In some embodiments, the folding assembly and the display panel are connected through a movable connecting part, and the folding assembly and the display panel are slid and fixed by using the flexible connection and fixation of the movable connecting part: when the reel assembly is unlocked, the movable connecting part is synchronously unlocked, the folding assembly and the display panel can slide relatively, specifically, the folding assembly is kept fixed, when the reel assembly is unlocked, the part of the display panel rolled on the reel assembly is unfolded, and the unfolded part can slide above the folding assembly, so that the aim of folding the display panel at a fixed position is not needed in the folding process of the display panel is fulfilled; when the reel assembly is locked, the movable connecting part is synchronously locked, and the folding assembly and the display panel are kept relatively fixed.
compared with the related art, the folding assembly and the display panel in the embodiment can adopt a movable connection mode to replace a fixed connection mode, and the scroll assembly provided by the embodiment is combined, so that when the display panel is repeatedly folded, the display panel does not need to be bent at a fixed position, the problems of material loss and the like caused by bending the flexible display screen at the fixed position are solved, and the service life of the flexible display screen is effectively prolonged.
Specifically, the rotating structure 331 and the reel assembly 32 are spatially arranged in parallel.
In this embodiment, set up to be parallel in space through rotating-structure and spool subassembly for flexible display panel's folding and rolling direction are unanimous, thereby so that display panel when rotating along with rotating-structure and folding, thereby the display panel of rolling protection part that the spool subassembly can be faster expandes, and can effectively prevent that display panel from producing the scheduling problem because of folding direction and rolling/the inconsistent display panel that leads to of expansion direction easily.
