The flexible display panel 300 has a first end and a second end, at least one of the first end and the second end is connected to the winding shaft 200, that is, the winding shaft 200 may be connected to the first end of the flexible display panel 300 and may also be connected to the second end of the flexible display panel 300, if the number of the winding shafts 200 is at least two, different winding shafts 200 may be respectively connected to the first end and the second end of the flexible display panel 300, and the connection manner may include various bonding methods, which is not particularly limited in this embodiment of the application, and the flexible display panel 300 may be at least partially wound around the winding shaft 200. It should be noted that no matter which setting mode is adopted between the flexible display screen 300 and the winding shaft 200, when a user needs to expand the display screen of the electronic device, the winding shaft 200 may be rotated to separate the portion of the flexible display screen 300 wound on the winding shaft 200 from the winding shaft 200, so that the distance between the first end and the second end of the flexible display screen 300 is increased, and the display area of the electronic device is increased to meet the user requirement; when the use is completed, the winding shaft 200 may be rotated reversely to wind more parts of the flexible display 300 on the winding shaft 200, and at this time, the distance between the first end and the second end of the flexible display 300 becomes smaller, so that the display area of the electronic device becomes smaller. Secondly, at least part of the flexible display screen 300 is wound on the winding shaft 200, so that the flexible display screen 300 can be prevented from being folded, and the user experience is improved.
The first driving mechanism 400 includes a driving source 410, and the driving source 410 may be a motor, a hydraulic cylinder, or the like, and embodiments of the present application are not particularly limited. The driving source 410 is connected to at least one of the first end and the second end, the driving source 410 drives the flexible display panel 300 to switch between the extended state and the retracted state, the driving source 410 is provided with an output shaft, and the extension direction of the output shaft is parallel to the extension direction of the winding shaft 200, wherein, in the extended state, the distance between the first end and the second end is a first distance; in the contracted state, the distance between the first end and the second end is a second distance, and the first distance is greater than the second distance. Specifically, in the case where the driving source 410 is connected to the first end of the flexible display 300, when a user needs to expand the display of the electronic device, the driving source 410 acts on the first end of the flexible display 300, and at this time, since the second end of the flexible display 300 is connected to the winding shaft 200, the winding shaft 200 rotates relative to the device body 100, so that the portion of the flexible display 300 wound around the winding shaft 200 is separated from the winding shaft 200, that is, the distance between the first end and the second end of the flexible display 300 becomes large; similarly, in the case that the driving source 410 is connected to the second end of the flexible display 300, when the user needs to expand the display of the electronic device, the driving source 410 acts on the second end of the flexible display 300, at this time, since the first end of the flexible display 300 is connected to the winding shaft 200, the winding shaft 200 rotates relative to the device body 100, so that the portion of the first end of the flexible display 300 wound on the winding shaft 200 is separated from the winding shaft 200, that is, the distance between the first end and the second end of the flexible display 300 becomes larger; when the number of the winding shafts 200 is at least two, the driving source 410 may be simultaneously connected to the first end and the second end of the flexible display 300, and when the user needs to expand the display of the electronic device, the driving source 410 simultaneously acts on the first end and the second end of the flexible display 300, so that the distance between the first end and the second end of the flexible display 300 is increased, and at this time, the winding shafts 200 connected to the first end and the second end of the flexible display 300 rotate relative to the device body 100, so that the display area of the flexible display 300 is increased. After the use is completed, the first end and/or the second end of the flexible display 300 can be manually pushed, so that the distance between the first end and the second end of the flexible display 300 is reduced, and at this time, the winding shaft 200 can reversely rotate, so that the display area of the flexible display 300 is reduced.

The driving source 410 can drive the first end of the flexible display screen 300 to move through the first casing 110, in this case, the winding shaft 200 is disposed in the first casing 110, since the winding shaft 200 can rotate relative to the apparatus main body 100, the winding shaft 200 can also rotate relative to the first casing 110, the driving source 410 drives the first casing 110 to move, the first casing 110 will drive the first end of the flexible display screen 300 to move, and the distance between the first end and the second end of the flexible display screen 300 becomes larger; similarly, the driving source 410 may also drive the second end of the flexible display screen 300 to move through the second housing 120, in this case, the winding shaft 200 is disposed in the second housing 120, the winding shaft 200 can rotate relative to the second housing 120, the driving source 410 drives the second housing 120 to move, and the second housing 120 drives the second end of the flexible display screen 300 to move, so that the distance between the first end and the second end of the flexible display screen 300 is increased; when the number of the winding shafts 200 is at least two, the driving source 410 may simultaneously drive the first end and the second end of the flexible display screen 300 to move through the first casing 110 and the second casing 120, and in this case, the driving source 410 may simultaneously drive the first casing 110 and the second casing 120 to move, so that the first casing 110 and the second casing 120 simultaneously drive the first end and the second end of the flexible display screen 300 to move, and the distance between the first end and the second end of the flexible display screen 300 becomes larger. Therefore, in the embodiment of the present application, the first housing 110 and the second housing 120 may not only provide a mounting base for other components of the electronic device, but also protect structures disposed in the first housing 110 and the second housing 120, thereby reducing wear; secondly, the first housing 110 and the second housing 120 are connected to the first end and the second end of the flexible display screen 300, respectively, so that the first housing 110 or the second housing 120 can be maintained conveniently after being damaged by multiple uses.

Because the first end of the flexible display screen 300 is connected to the first housing 110 and the second end of the flexible display screen 300 is connected to the second housing 120, when a user needs to use the large-screen electronic device, the driving source 410 drives the first housing 110 and the second housing 120 to move at the same time, so that the first housing 110 and the second housing 120 are relatively far away, and thus the first end and the second end of the flexible display screen 300 are relatively far away under the driving of the first housing 110 and the second housing 120, and the display area of the electronic device is enlarged; after the electronic device is used, the driving source 410 drives the first casing 110 and the second casing 120 to move in opposite directions at the same time, so that the first casing 110 and the second casing 120 are relatively close to each other, and the first end and the second end of the flexible display screen 300 are relatively close to each other under the driving of the first casing 110 and the second casing 120, at this time, the display area of the electronic device is reduced, and the overall size of the electronic device is smaller. Therefore, in the embodiment of the present application, only one driving source 410 may be used to drive the first end and the second end of the flexible display screen 300, thereby improving the efficiency of distance change between the first end and the second end of the flexible display screen 300 and reducing the cost of the electronic device.
In the above embodiment, if the driving source 410 is directly connected to the first housing 110 and the second housing 120, the first housing 110 and the second housing 120 may be damaged after the driving source 410 drives the first housing 110 and the second housing 120 to move for a plurality of times.
