Fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present application.

The display device provided by the embodiment of the application comprises a flexible panel assembly 100, a rotating shaft 300, a medium conveying member 200 and a first linkage assembly 400.

The flexible panel assembly 100 includes a flexible panel 110 and a capsule 120 stacked in a thickness direction thereof. The flexible panel 110 may be an Organic Light Emitting Diode (OLED) display panel. The capsule body 120 is disposed on the back side of the flexible panel 110, and the capsule body 120 is a flexible member, and may be made of a flexible material, so that the capsule body 120 can deform along with the flexible panel 110.

The rotating shaft 300 is used for winding the flexible panel assembly 100, and the rotating shaft 300 can rotate around its center axis in a first rotating direction P and a second rotating direction Q opposite to the first rotating direction P, so as to unfold or store the flexible panel assembly 100. It is understood that the flexible panel assembly 100 may have an unfolded state, a stored state and an intermediate state between the unfolded state and the stored state, the flexible panel assembly 100 is connected to the rotating shaft 300, and specifically, one end of the flexible panel assembly 100 is connected to the rotating shaft 300, so that the rotating shaft 300 may drive the flexible panel assembly 100 to transition between the stored state, the intermediate state and the unfolded state. Optionally, when the rotating shaft 300 rotates in the first rotating direction P, the flexible panel assembly 100 is gradually unfolded from the rotating shaft 300, and when the rotating shaft 300 rotates in the second rotating direction Q, the flexible panel assembly 100 is gradually wound around the rotating shaft 300.

The media transport 200 is capable of providing media to the capsule 120. The first linkage assembly 400 is connected between the rotating shaft 300 and the medium delivery member 200, the first linkage assembly 400 is arranged in linkage with the rotating shaft 300, and when the rotating shaft 300 drives the flexible panel assembly 100 to be in the unfolding state and the accommodating state, the first linkage assembly 400 prevents the medium delivery member 200 from providing the medium to the capsule 120, and when the rotating shaft 300 drives the flexible panel assembly 100 to be in the intermediate state, the medium delivery member 200 is communicated with the capsule 120, so that the medium delivery member 200 can input the medium into the capsule 120 or discharge the medium from the capsule 120.

It is understood that when the flexible panel assembly 100 is in the storage state, the bladder 120 may be empty of medium, so as to facilitate the flexible panel assembly 100 to be wound on the rotating shaft 300; when the rotating shaft 300 rotates to drive the flexible panel assembly 100 to gradually change from the storage state to the expansion state, the medium may be input into the capsule 120 through the medium conveying member 200, so that the capsule 120 gradually swells (i.e., the size of the capsule 120 in the thickness direction of the flexible panel assembly 100 gradually increases) and provides support for the flexible panel 110, and the capsule 120 may assist the flexible panel 110 to smoothly expand; when the rotating shaft 300 drives the flexible panel assembly 100 to be unfolded to the unfolded state, the first linkage assembly 400 prevents the medium delivery member 200 from continuously providing the medium to the capsule 120, so as to prevent the medium in the capsule 120 from leaking or the medium from excessively damaging the capsule 120; when the rotating shaft 300 rotates to drive the flexible panel assembly 100 to be converted to the storage state, the medium conveying member 200 may discharge the medium to the capsule 120, so that the size of the capsule 120 in the thickness direction of the flexible panel assembly 100 is gradually reduced, and the flexible panel assembly 100 may be curled, so as to store the flexible panel 110.

According to the display device provided by the embodiment of the application, the capsule 120 is arranged on one side of the flexible panel 110, and the action of filling the capsule 120 with the medium is linked with the state of the flexible panel assembly 100, so that the state that the capsule 120 is filled with the medium and follows the flexible panel 110 is changed, the flexible panel assembly 100 is convenient to store and expand, the smoothness and the stability of the expanded state of the flexible panel 110 can be improved by using the capsule 120, and the adverse effect of the use environment on the flexible panel 110 is reduced.

It should be noted that the capsule 120 is used for supporting and protecting the flexible panel 110, and the capsule 120 covers at least the peripheral side area of the back surface of the flexible panel 110, so that when the flexible panel 110 is in the unfolded state, the capsule 120 can support the flexible panel 110 at each edge of the flexible panel 110 to keep the flexible panel 110 in the unfolded state.

Optionally, the shape of the bladder 120 may be designed according to the shape of the flexible panel 110, so as to be adaptable to the flexible panel 110 with various shapes, and achieve the effect of better supporting and protecting the flexible panel 110. As an alternative embodiment, the flexible panel 110 may be rectangular when unfolded, or the whole 120 may be rectangular when filled with a medium.

One end of the flexible panel assembly 100 is generally connected to the rotating shaft 300 to facilitate winding, and the medium feeding member 200 is communicated with the capsule 120 by using the rotating shaft 300, which is simple and convenient and can simplify the structure of the display device. Of course, a communication line may be additionally provided to connect the medium delivery member 200 and the bladder 120, and still be within the scope of the present application.

Optionally, the first vent hole 303 on the first end plate 311 may be shielded by attaching the partition plate 412 to the first end plate 311, and the first vent hole 303 on the second end plate 321 may be shielded by attaching the partition plate 412 to the second end plate 321.

According to the display device provided by the embodiment of the present application, the rotating shaft 300 is coupled with the first linkage assembly 400, so that the medium is supplied to the capsule 120 using the medium delivering member 200; and the state of the rotation shaft 300 actually controls the unfolded state of the flexible panel 110 and the capsule 120; therefore, real-time follow-up of the filling condition of the capsule 120 and the unfolding condition of the flexible panel 110 is realized, and delay is avoided.

As another alternative embodiment, the first driving member 500 may be connected to the converting mechanism 420, and the first driving member 500 drives the first gear 421 and the second bevel gear 422, which are coaxially disposed, to synchronously rotate, so that the rotating shaft 300 is driven to rotate by the first gear 421, and the sliding sleeve 410 is driven to rotate by the second bevel gear 422, and at the same time, the sliding sleeve 410 moves in the axial direction of the rotating shaft 300, which is also within the protection scope of the present application.

It should be noted that the present application is not limited to the media provided by the media delivery member 200 to the capsule 120. Alternatively, the bladder 120 may be a balloon and the medium may be a gas; of course, it is also within the scope of the present application to select a liquid, such as water, as the medium for filling the bladder 120.

As an alternative embodiment, as shown in fig. 3, the first linkage assembly 400 may include a sleeve 411 and a conversion mechanism 420, and the push-pull rod 200 and the sleeve 411 may be fixedly connected through a connecting member, and when the rotating shaft 300 rotates, the conversion mechanism 420 converts the rotation of the rotating shaft 300 into a linear motion of the sleeve 411 in the axial direction of the rotating shaft 300, so as to implement the linear motion of the push-pull rod 200 in the axial direction of the rotating shaft 300.
