The flexible display device 100 also has a third form. Referring to FIGS. 6 and 7, FIG. 6 is a schematic perspective view of the flexible display device in FIG. 1 in the third form, and FIG. 7 is a partial side view of the flexible display device in FIG. 1 in the third form. In the third form, the flexible display panel 30 is scrolled, and the second housing 20 presses against one edge of the first housing 10. The third form can also be referred as a “turned-off form”. Referring to FIG. 8, it is a partial side view of the flexible display device in FIG. 1 in a fourth form. In the fourth form, the second housing 20 is away from the first housing 10, a second included angle β, which is greater than the first included angle α, is formed between the flexible display panel 30 and the first surface 10a. The second included angle β is greater than or equal to 180° and less than 360°. The fourth form can also be referred as a “tablet-computer-with-stand form”. Components and forms of the flexible display device 100 are described in detail hereinbelow.

The first housing 10 serves as a base of the laptop computer in the first form, serves as a backplane of the tablet computer in the second form, serves as a housing of the tablet computer in the third form, and serves as a stand of a tablet computer in the fourth form. A shape of the first housing 10 is not defined in the present disclosure. In an embodiment, in order to be compatible with multiple forms described in the present disclosure, the first housing 10 is essentially rectangular. A long side direction of the first housing 10 is a first direction D1, and a short side direction of the first housing 10 is a second direction D2. In an embodiment, a keyboard K and a touchpad T are disposed on the first surface 10a of the first housing 10. In another embodiment, the keyboard K is detachably disposed on the first surface 10a. In the first form, the flexible display device 100 is used as a laptop computer. Compared with a virtual keyboard, the keyboard K disposed on the first surface 10a can provide the user with real touch sense, thereby enhancing user experience. The second surface 10b is a flat surface. Therefore, in the second form, the flexible display panel 30 may be disposed on the second surface 10b for displaying and touch controlling.

The first housing 10 is also used for containing the flexible display panel 30. One end of the flexible display panel 30 is curlably disposed on the first housing 10. Specifically, the first housing 10 includes a first scroll 11, one end of the flexible display panel 30 is scrollably disposed on the first scroll 11, and the other end of the flexible display panel 30 is fixedly connected to the second housing 20. The flexible display panel 30 can be scrolled onto the first scroll 11, thereby decreasing a size of the flexible display device 100, and thereby enhancing portability. A location of the first scroll 11 is not defined in the present disclosure. The first scroll 11 can be located at a surface of the first housing 10 facing the second housing 20, or the first scroll 11 can also be contained inside the first housing 10. As shown in FIG. 2, in an embodiment, in order to prevent the flexible display panel 30 from being damaged by external forces, the first housing 10 includes a hollow cavity 101. The first scroll 11 is contained inside the hollow cavity 101. The first scroll 11 extends along the first direction D1. An opening 102 is formed at an end of the first housing 10 close to the second housing 20. The opening 102 is connected with the hollow cavity 101. The flexible display panel 30 connects the second housing 20 and the first scroll 11 through the opening 102. Specifically, the first scroll 11 is disposed on one end of the hollow cavity 101 away from the opening 102. It is understandable that the hollow cavity 101 may also be used to contain other components of the flexible display device 100, such as a driving circuit board for the flexible display panel 30.

The second housing 20 is disposed in the second direction D2 of the first housing 10, that is, the short side direction. In an embodiment, the second housing 20 extends along the first direction D1, and a length of the second housing 20 is essential the same as a length of the first housing 10. A shape of the second housing 20 is not defined in the present disclosure. The shape of the second housing 20 may be cylindrical, rectangular parallelepiped, or prismatic. In the present embodiment, the second housing 20 is cylindrical. Specifically, the second housing 20 includes a second scroll 21 which extends along the first direction D1. The second scroll 21 can scroll the flexible display panel 30 onto the second housing 20 by rotation, thereby covering at least part of an outer surface of the second housing 20, and thereby increasing a display area. For example, referring to FIG. 3, in the second form, the flexible display panel 30 is scrolled on the second scroll 21 and covers at least part of a surface of the second scroll 21. The flexible display device 100 may also has a fifth form. Referring to FIG. 9, the fifth form is configured base on the first form by rotating the second scroll 21, so as to scroll the flexible display panel 30 on the second housing 20 and cover at least part of the outer surface of the second housing 20, thereby increasing the display area. In another embodiment, the flexible display panel 30 has a display surface 30a and a non-display surface 30b, and the non-display surface 30b of the flexible display panel 30 is fixedly connected to the second housing 20. For example, when the second housing 20 includes the second scroll 21, the flexible display panel 30 is always scrolled on the second scroll 21, and no matter how the flexible display device 100 changes its form, the second housing 20 is always located at the non-display surface 30b of the flexible display panel 30, so as to achieve a maximal display area.

The second housing 20 is configured for moving relative to the first housing 10. Specifically, the second housing 20 may move away from, move close to the first housing 10, rotate around the first housing 10, or rotate around the first housing 10 while moving away from or moving close to the first housing 10. The flexible display panel 30 can be deployed or scrolled between the first housing 10 and the second housing 20 according to the relative motion between the second housing 20 and the first housing 10.

The flexible display panel 30 is used for displaying images. The flexible display panel 30 can be scrolled onto the first scroll 11 in the second direction D2, or the flexible display panel 30 can be deployed from the first scroll 11 in the second direction D2. In the present embodiment, the flexible display panel 30 can also be scrolled onto the second scroll 21 in the second direction D2, or the flexible display panel 30 can be deployed from the second scroll 21 in the second direction D2.

The flexible display panel 30 may be an Organic Light-emitting Diode (OLED) display panel, an Active Matrix Organic Light-emitting Diode (AMOLED) display panel, a Passive Matrix Organic Light-emitting Diode (PMOLED) display panel, a Quantum Dot Light-emitting Diode (QLED) display panel, a Micro Light-emitting Diode (Micro-LED) display panel, or a Mini Light-emitting Diode (Mini-LED) display panel.

In the first form, a first included angle α is formed between the flexible display panel 30 and the first surface 10a, and the first included angle α is greater than 0° and less than 180°. In the second form, the flexible display panel 30 covers the second surface 10b. The flexible display panel 30 further comprises a touch module. In the second form, the first housing 10 is configured to provide a rigid supporting surface of the touch module, and the flexible display panel 30 may achieve touch control. Specifically, the flat second surface 10b provides the rigid supporting surface of the touch module.

Referring to FIG. 1, the flexible display device 100 further comprises a support component 40. In the present embodiment, one end of the support component 40 is rotatably connected to the first housing 10 and another end of the support component 40 is fixedly connected to the second housing 20. In the first form, a third included angle γ is formed between the support component 40 and the first surface 10a so as to support the second housing 20. The third included angle γ is greater than 0° and less than 180°. In the second form, the support component 40 is parallel to the first housing 10, so as to fix the flexible display panel 30 to the second surface 10b. Specifically, the second housing 20 further includes connecting portions 22 located at both sides of the second scroll 21. The support component 40 is fixedly connected to the connecting portions 22. In the present embodiment, the connecting portions 22 are insert pins. Sockets are formed in the support component 40. The insert pins are inserted into the sockets, so as to be fixedly connected to the support component 40. It is understandable that a manner by which the connecting portions 22 and the support component 40 are connected is not defined in the present disclosure.

The support component 40 is disposed on both sides, along the first direction D1, of the first housing 10. In an embodiment, the support component 40 is telescopic. Specifically, the support component 40 includes a first telescopic rod 41, a second telescopic rod 42, a third telescopic rod 43, and a fourth telescopic rod 44. The first telescopic rod 41 is rotatably connected to the first housing 10. The second telescopic rod 42 is fixedly connected to the second housing 20. One end of the third telescopic rod 43 is slidably connected to the first telescopic rod 41, and another end of the third telescopic rod 43 is slidably connected to the fourth telescopic rod 44. One end of the fourth telescopic rod 44 is slidably connected to the third telescopic rod 43, and another end of the fourth telescopic rod 44 is slidably connected to the second telescopic rod 42. It is understandable that the number of the telescopic rods that the support component 40 includes is not defined in the present disclosure. In addition, telescopic structure of the support component 40 is also not defined in the present disclosure, any kind of structure that is capable of changing length may be used as the support component 40 of the present disclosure. “Z” or “X” shaped hinge structures may be taken as specific examples. Because the support component 40 is rotatable around the first housing 10, by rotating the support component 40, relative positions of the first housing 10 and the second housing 20 may be adjusted, thereby adjusting an angle formed between the flexible display panel 30 and the first housing 10. Because the support component 40 is telescopic, by adjusting a length of the support component 40, a distance between the first housing 10 and the second housing 20 may be adjusted, thereby adjusting a size of the flexible display panel 30.

In an embodiment, the support component 40 may be an electrical support component 40. Referring to FIG. 2, the flexible display device 100 further comprises a driving component 50 for the support component 40. The driving component 50 is used for driving the support component 40 to extend and contract and/or to rotate. The driving component 50 can be disposed inside the hollow cavity 101. By driving the support component 40 to extend, the driving component 50 drives the second housing 20 to move relative to the first housing 10, thereby releasing the flexible display panel 30 from the first scroll 11, and thereby deploying the flexible display panel 30 between the first housing 10 and the second housing 20. On the contrary, by driving the support component 40 to contract, and cooperating with a rotation of the first scroll 11, the driving component 50 scrolls the flexible display panel 30 onto the first scroll 11, thereby shortening the flexible display panel 30 between the first housing 10 and the second housing 20. In addition, by driving the support component 40 to rotate, the angle formed between the flexible display panel 30 and the first housing 10 can be adjusted, thereby switching the flexible display device 100 between the multiple forms.

In is noted that, in an embodiment, the support component 40 is detachably connected to the first housing 10 and/or to the second housing 20. Specifically, in an embodiment, in the third form, the support component 40 is detached from under the first housing 10 and the second housing 20. In a process in which the flexible display device 100 is switched from the third form to the first form, the second housing 20 is moved away from the first housing 10, the flexible display panel 30 is deployed, then the support component 40 is respectively attached to the first housing 10 and the second housing 20, so as to support the second housing 20 on the first housing 10, thereby fixing the flexible display panel 30. In a process in which the flexible display device 100 is switched from the third form or the first form to the second form, the support component 40 can be detached from under the first housing 10 and from the second housing 20, the second housing 20 is adjusted to an edge, which is away from the opening 102 in the second direction D2, of the first housing 10, so that the flexible display panel 30 covers the second surface 10b. Then the support component 40 is respectively attached to the first housing 10 and to the second housing 20, thereby fixing positions of the first housing 10 and the second housing 20. It is understandable that in the second form, the second housing 20 may contact the first housing 10, or the second housing 20 may keep certain distance with the first housing 10. In an embodiment, the support component 40 may be rotatably connected to the first housing 10, but is detachably connected to the second housing 20, and is connected to the second housing 20 after the location of the second housing 20 is adjusted, so as to fix the second housing 20. Referring to FIG. 10, it is a schematic perspective view of a flexible display device in a second form, provided by another embodiment of the present disclosure. In another embodiment, in the second form, the support component 40 is detached form under the first housing 10 and the second housing 20. Present, the flexible display device 100 further comprises a fixing component 60. In the second form, the fixing component 60 fixes the second housing 20 onto the first housing 10, thereby fixing the flexible display panel 30 to the second surface 10b.

In an embodiment, especially when the support component 40 is detachably connected to the first housing 10 and/or to the second housing 20, the support component 40 may also be of a fixed length.

Referring to FIGS. 2 and 5 again, the flexible display device 100 further comprises a first roller 70 and a second roller 80, both located between the first scroll 11 and the second housing 20. In an embodiment, the first roller 70 and the second roller 80 are disposed opposite each other. In an embodiment, the first roller 70 and the second roller 80 are both disposed inside the opening 102 and are respectively located at one of the sides of the first housing 10 in a thickness direction of the first housing 10. The first roller 70 and the second roller 80 are for sliding relatively to the flexible display panel 30 during the deployment or scrolling of the flexible display panel 30, so as to keep the flexible display panel 30 from being damaged by friction. In the first form, the flexible display panel 30 contacts the first roller 70. In addition, the flexible display panel 30 is bent by the first roller 70 acting as an inflection point. Due to a surface contact between the flexible display panel 30 and a curved surface of the first roller 70, a friction is reduced, and the flexible display panel 30 is therefore protected. In the second form, the flexible display panel 30 contacts the second roller 80. In addition, the flexible display panel 30 is bent by the second roller 80 acting as the inflection point. Due to the face contact between the flexible display panel 30 and a curved surface of the second roller 80, a friction is reduced, and the flexible display panel 30 is therefore protected.

The first to the fifth form of the flexible display device 100 of the present disclosure and switching processes between the forms are described in detail hereinbelow. The flexible display device 100 of the present disclosure may be switched between any two of the forms from the first to the fifth form. The switching processes are only described by way of example hereinbelow.

Firstly, referring to FIGS. 6 and 7, the third form may be an initial form of the flexible display panel 30. In the third form, the second housing 20 presses against one edge, in the second direction D2, of the first housing 10. One end of the flexible display panel 30 is scrollably fixed to the first scroll 11 and the other end of the flexible display panel 30 is fixed onto the second housing 20. The flexible display panel 30 and the first scroll 11 are contained together inside the hollow cavity 101 of the first housing 10. The support component 40 is located at both edges of the first housing 10 in the first direction D1, and is disposed parallel to the first housing 10, thereby reducing the space occupied by the flexible display device 100.

Referring to FIG. 2, during a process in which the flexible display device 100 is switched from the third form to the first form, the driving component 50 drives the support component 40 to extend, and stop when a predetermined length is reached, thereby bringing the second housing 20 away from the first housing 10, thereby releasing the flexible display panel 30 from the first scroll 11, and thereby deploying the flexible display panel 30 in the second direction D2. Then the driving component 50 further drives the support component 40 to rotate in a direction, which is away from the first surface 10a, until a predetermined angle is reached, so as to form the first included angle a between the flexible display panel 30 and the first surface 10a. In the process, the flexible display panel 30 and the first roller 70 slide relatively to each other. It is understandable that an order that the driving component 50 drives the support component 40 to extend and to rotate may be reversed, and the driving component 50 may also drives the support component 40 to extend and to rotate at the same time.

Referring to FIG. 9, because in the first form, the second housing 20 is located at the display surface 30a of the flexible display panel 30, and the flexible display panel 30 may be scrolled onto the second scroll 21 by rotating the second scroll 21, so that the flexible display panel 30 covers the surface of the second housing 20 and relocates the second housing 20 onto the non-display surface 30b of the flexible display panel 30, thereby increasing the display area of the flexible display device 100. This is the fifth form.

Referring to FIG. 8, during a process in which the flexible display device 100 is switched from the first form or the fifth form to the fourth form, the driving component 50 drives the support component 40 to further rotate in the direction away from the first surface 10a, and stop when a predetermined angle is reached. During this process, the support component 40 rotates the second housing 20 around the first housing 10, and forms the second included angle β between the flexible display panel 30 and the first surface 10a. The second included angle β is greater than or equal to 180° and less than 360°.
