Referring to fig. 1 and 2, fig. 1 illustrates a state where an electronic device is worn to a wrist, and fig. 2 illustrates a state where the electronic device of fig. 1 is bent. The electronic device 100 provided in the embodiment of the application may be a mobile phone or a tablet computer, and in other embodiments, the electronic device 100 may also be other structures having the display function of the flexible display panel 11, for example, a wearable watch or a bracelet, which is not limited herein.

For convenience of understanding, the structure of the electronic device 100 is described below by taking a mobile phone as an example.

The electronic device 100 comprises a display screen 10 and a housing 20, wherein the display screen 10 is used for providing a display function and a touch control function for a user, and the housing 20 is used as an appearance structural member of the electronic device 100 and can have a good protection effect on the display screen 10. In some embodiments, the cavity formed by the display screen 10 and the housing 20 can be used to mount a battery, a motherboard, and the like.

The display screen 10 includes a flexible display panel 11 and a screen support structure 12 (see fig. 7). The display surface 10a is provided on one side of the display surface 10a for displaying a screen, and when the electronic device 100 displays a screen, the display surface 10a displays a content such as a character or a pattern to be displayed.

The screen support structure 12 is disposed on a side of the flexible display panel 11 opposite to the display surface 10a, and can provide a good support effect for the flexible display panel 11. In this embodiment, the screen support structure 12 is used for supporting the flexible display panel 11, and the screen support structure 12 is used for driving the flexible display panel 11 to expand or contract along a first direction X (shown in fig. 2), so as to adjust the width of the display surface 10a in the first direction X. The screen support structure 12 can drive the flexible display panel 11 to bend around the first direction X, that is, the flexible display panel 11 can be driven by the screen support structure 12 to bend along a second direction W (shown in fig. 2) around the first direction X.

In the above embodiment, the screen support structure 12 can drive the flexible display panel 11 to surround the first direction X, so as to adjust the flexible display panel 11 to surround the state of the first direction X, so that the electronic device 100 can be worn to the wrist or ankle, and at this time, the electronic device 100 surrounds the wearing position, so that the stability is good, the carrying is convenient, and the wearable use experience is adopted, so that the technological sense is also improved. Because screen bearing structure 12 can adjust the demonstration width of flexible display panel 11, then when wearing the crooked use of electronic equipment 100, can shrink flexible display panel 11 along first direction X to narrow flexible display panel 11, narrower flexible display panel 11 can provide better skin-contacting feel, thereby promote to wear to use and experience.

With reference to fig. 3, 4 and 7, when the electronic device is not worn for use, the screen supporting structure 12 may be flattened, and the screen supporting structure 12 of the electronic device 100 drives the display surface 10a to be unfolded along the first direction X, so as to restore the large-screen display effect, thereby effectively meeting the handheld use experience of the user.

It should be noted that the screen supporting structure 12 is used to drive the flexible display panel 11 to expand or contract along the first direction X, and may be used to drive the screen supporting structure 12 to drive two opposite sides of the flexible display panel 11 to simultaneously expand or contract along the first direction X (shown in fig. 3 and 4), and in other embodiments, as shown in fig. 5 and 6, the screen supporting structure 12 may also drive one side of the flexible display panel 11 to expand or contract along the first direction X, which is not limited herein.

Specifically, taking the area of the display surface 10a for displaying the display image to define the bright screen area of the display screen 10 as an example, the screen supporting structure 12 can drive the flexible display panel 11 to bend around the first direction X toward the bright screen area. In some embodiments, the screen support structure 12 can drive the flexible display panel 11 to bend around the first direction X toward the side facing away from the bright screen area. In some embodiments, the screen supporting structure 12 can drive the flexible display panel 11 to bend around the first direction X toward the side of the bright screen area, and can also drive the flexible display panel 11 to bend around the first direction X toward the side of the bright screen area.

Since the portion of the display surface 10a of the flexible display panel 11 is accommodated inside and not exposed during the expansion or contraction of the flexible display panel 11 along the first direction X, the portion does not present a display picture, and based on this, the bright screen region refers to the portion of the display surface 10a exposed out of the housing 20. Then, when the bright screen area lights up or displays a screen, the content displayed in the bright screen area can be completely observed outside the electronic device 100.
