The fixed end and the free end are respectively located at two ends of the flexible panel body 110 along a first direction (i.e., a left-right direction in the figure), the fixed end is used for being fixedly disposed on the housing 120, wherein the flexible display panel further includes a main positioning element 131 disposed at the free end, and the main positioning element 131 is used for being detachably connected with an auxiliary positioning element on the housing 120.

The housing 120 can be switched between a plurality of states, which include a flat state and at least one bent state, wherein, as described above, the flexible display panel further includes a main positioning element 131 disposed at the free end, the housing assembly further includes a plurality of auxiliary positioning elements, each of the auxiliary positioning elements corresponds to one state of the housing 120, and the auxiliary positioning elements are used for being detachably connected with the main positioning element 130 on the flexible display panel in a state corresponding to the auxiliary positioning element.

Hereinafter, the working principle and the beneficial effect of the housing assembly and the flexible display panel will be described in detail with reference to the flexible display device including the housing assembly and the flexible display panel, which is not repeated herein.
As a third aspect of the present invention, there is provided a flexible display device, wherein the flexible display device includes the above flexible display panel provided by the present invention and the above housing provided by the present invention.
The flexible display panel is arranged in a housing 120, the fixed end is fixedly arranged on the housing, and the free end can move in the housing 120 when the housing 120 is switched.
In each state of the housing 120, the main positioning member 131 can be detachably fixed on the corresponding auxiliary positioning member, and tension the flexible panel body 110.
In the flexible display device provided by the invention, no matter what state the housing 120 is, the flexible panel body 110 is in a tensioned state, so that the smoothness of the display surface of the flexible panel is ensured, and the user experience is improved. When the state is switched, the joint state between the main positioning member 131 and the corresponding auxiliary positioning member can be released, so that the flexible panel body 110 can be deformed along with the deformation of the housing, thereby completing the state switching.
In the present invention, the specific structure of the housing 120 is not particularly specified. For example, as an embodiment of the present invention, the housing 120 may be a flexible housing. Of course, the housing 120 may also include a combination of flexible and rigid portions.
As a preferred embodiment of the present invention, as shown in fig. 1, the housing 120 includes a plurality of housing areas 121 arranged in sequence along a first direction, and adjacent two housing areas 121 can relatively rotate around an intersection between the two housing areas 121 to switch the housing 120 between a plurality of states, including a flattened state (shown in fig. 1) and at least one bent state (shown in fig. 2). In this embodiment, a plurality of the auxiliary positioning members are spaced along the first direction, and the free end of the flexible panel body 110 can move along the first direction in the housing 120 when the housing 120 switches states.
As shown in fig. 1, the flexible panel body 110 is disposed in the housing 120, and the flexible panel body 110 includes a fixed end and a free end, the fixed end and the free end are respectively located at two ends of the flexible display panel along the first direction, the fixed end is fixedly disposed on the housing 120, and the free end can move in the first direction in the housing 120 when the housing 120 switches states.
When the housing 120 is in any one state, the main positioning member 131 is attracted to the corresponding auxiliary positioning member, so that the flexible display panel is tensioned and the display surface of the flexible display panel is maintained flat.
When the housing 120 switches states, the main positioning member 131 is separated from the auxiliary positioning member, so that the free end of the flexible display panel can move to switch states.
In the embodiment shown in fig. 1 and 2, the housing 120 has two states, a flattened state and a bent state. The auxiliary positioning element includes an auxiliary positioning element 132a corresponding to a flattened state and an auxiliary positioning element 132b corresponding to a bent state, wherein the auxiliary positioning element 132a is located outside the auxiliary positioning element 132 b.
Shown in fig. 1 is the flexible display device in a flattened state. As shown in fig. 1, the main positioning member 131 provided at the free end of the flexible panel body 110 is engaged with the auxiliary positioning member 132a located at the outermost side of the flexible display panel, so that the position of the free end of the flexible display panel can be fixed and the flexible panel body 110 can be tensioned.
Shown in fig. 2 is the flexible display device in a flexed state. As shown in fig. 2, the main positioning member 131 disposed at the free end of the flexible panel body 110 is engaged with the auxiliary positioning member 132b disposed inside the auxiliary positioning member 132a, so as to fix the position of the free end of the flexible panel body 110 and tension the flexible panel body 110 in the bent state.
In the present invention, the first direction is the left-right direction shown in fig. 1. The term "inner side" as used herein refers to a side near the middle of the housing 120, and the term "outer side" refers to a side near the edge of the housing 120.
The free end of the flexible display panel moves within the housing 120 when the housing is switched between the flattened state and the bent state. Because the auxiliary positioning parts are arranged at different positions, no matter what state the housing 120 of the flexible display device is, the free end of the flexible display panel is in a fixed state, so that the flexible display panel is in a tensioned state, the smoothness of the display surface is ensured, and the user experience can be improved.
In the present invention, the housing regions 121 may be rigid regions, and two adjacent housing regions 121 may be hinged together.
In the present invention, the type of the adsorption force between the main spacer 131 and the auxiliary spacer is not particularly required. For example, the main positioning member 131 may include a suction cup, and the suction between the main positioning member 131 and the auxiliary positioning member may be achieved by exhausting air to the main positioning member 131.
In the present invention, the main positioning member 131 and the auxiliary positioning member may be attracted together by magnetic force. The strength of the magnetic attraction is relatively small, which not only can maintain the tension state of the flexible display panel, but also is convenient for separation, so that the housing 120 realizes state switching.
The main positioning member 131 may be a magnet, and the auxiliary positioning member may be made of a ferromagnetic material. Or the main positioning member 131 may be made of a ferromagnetic material and the auxiliary positioning member is a magnet.

As described above, each state corresponds to an auxiliary positioning element. When the housing 120 is in a certain state, the auxiliary positioning member corresponding to the state is powered, and the other auxiliary positioning members are not powered, so that the main positioning member 131 arranged at the free end can be prevented from being attracted to the auxiliary positioning member not corresponding to the state, and the flexible display panel can be ensured to be in a tensioned state in each state, so that the user can obtain the best user experience.
For example, when the housing of the flexible display device is in the flat state shown in fig. 1, the control module is used to supply power to the outermost auxiliary positioning member. When the housing of the flexible display device is in the bent state shown in fig. 2, power is supplied to the inner auxiliary positioning piece by using the control module.
