Please refer to fig. 1 and fig. 2. Fig. 1 is an exploded view illustrating a display device 100 according to an embodiment of the present disclosure, and fig. 2 is an assembled view illustrating the display device 100 shown in fig. 1. The display device 100 includes a flexible display 110 and a receiving tube 120 for receiving the flexible display 110. The storage cylinder 120 includes a hollow cylindrical housing 121 and a rotation axis 122 rotatably disposed in the housing 121. The rotating shaft 122 has two

opposite end surfaces

122a, 122c and a slot 122b, and the slot 122b is an axial groove on the rotating shaft 122 and extends to at least one of the end surfaces 122 a. The housing 121 has an end surface 121a and an insertion opening 121b, the end surface 121a faces the end surface 122a of the insertion slot 122b, the insertion opening 121b is an axial opening of the housing 121 and extends to the end surface 121a, and the flexible display 110 is configured to be connected with the insertion slot 122b of the rotation axis 122 in an insertable and removable manner through the insertion opening 121b of the housing 121. In use, the flexible display 110 can be (1) separated from the receiving tube 120 for independent use; (2) connecting the storage barrel 120 and unfolding the storage barrel 120 for use; or (3) connect the storage tube 120 and roll up in the storage tube 120.

As shown in fig. 1 and fig. 2, the flexible display 110 can slide into and out of the slot 122b through the insertion opening 121b at one end of the end surface 121 a. In other embodiments, the insertion opening 121b extends to two opposite end surfaces of the housing 121, and the slot 122b extends to two opposite end surfaces of the rotation axis 122, so that the insertion opening 121b and the slot 122b can both allow the flexible display 110 to enter and exit.

As shown in fig. 1 and fig. 2, the flexible display 110 includes a back panel 111, a display panel 112 disposed on the back panel 111, a power transmission interface 113, and an electric energy storage device 114 (e.g., a battery). The electrical energy storage device 114 is configured to provide power to maintain the operation of the flexible display 110 when the flexible display 110 is separated from the receptacle 120. The electric energy storage device 114 is electrically connected to the power transmission interface 113 and the display panel 112, and the electric energy storage device 114 and the power transmission interface 113 are located on two opposite sides of the display panel 112.

As mentioned above, the flexible display 110 can be divided into the display area 110a and the first peripheral area 110b and the second peripheral area 110c located at two opposite sides of the display area 110a, the display panel 112 is located in the display area 110a, and the power transmission interface 113 and the electrical energy storage device 114 are respectively located in the first peripheral area 110b and the second peripheral area 110 c.
