The display device in the embodiment of the present application may be a vehicle-mounted head-up display device, and may also be other devices with a display function, such as a mobile phone, a tablet computer, and an electronic book.

Fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present disclosure; fig. 2 is a schematic three-dimensional structure diagram of a display device according to an embodiment of the present disclosure.

As shown in fig. 1 and 2, an embodiment of the present application provides a display device including a flexible display panel 10, a push assembly 20, and a pull housing assembly 30.

The flexible display panel 10 has a first end 110 and a second end 120 opposite to each other, and the flexible display panel 10 may be an Organic Light Emitting Diode (OLED) display panel.

The pushing assembly 20 acts on the first end portion 110 of the flexible display panel 10, the second end portion 120 of the flexible display panel 10 is disposed on the pulling accommodation assembly 30, and the pushing assembly 20 can drive the first end portion 110 of the flexible display panel 10 to move away from and close to the second end portion 120 in the first direction Z, so that the flexible display panel 10 is unfolded and accommodated.

The drawing and accommodating assembly 30 is used for accommodating the flexible display panel 10, the drawing and accommodating assembly 30 comprises a first supporting shaft 31 and a second supporting shaft 32, the flexible display panel 10 is wound on the second supporting shaft 32 and the first supporting shaft 31, and the first supporting shaft 31 and the second supporting shaft 32 can be arranged in a relatively movable mode, so that the first supporting shaft 31 and the second supporting shaft 32 can be close to and far away from each other, and further the distance between the second supporting shaft 32 and the first supporting shaft 31 is changed.

It can be understood that, during the unfolding process of the flexible display panel 10, the second support shaft 32 and the first support shaft 31 may approach each other, and the distance between the second support shaft 32 and the first support shaft 31 is reduced, so that at least a portion of the flexible display panel 10 can be released by the pull receiving assembly 30, and the flexible display panel 10 can be unfolded by an external force, thereby preventing the flexible display panel 10 from being torn due to hard pulling; the second supporting shaft 32 and the first supporting shaft 31 can be far away from each other in the accommodating process of the flexible display panel 10, and the distance between the second supporting shaft 32 and the first supporting shaft 31 is gradually increased, so that the flexible display panel 10 can be synchronously retracted to the drawing accommodating assembly 30 along with the return of the ejection assembly 20, and the phenomenon that the flexible display panel 10 is wrinkled is avoided.

In an initial state, the flexible display panel 10 can be accommodated in the drawing and accommodating assembly 30, so that the display device has a small volume and is convenient to carry and place; when the pushing assembly 20 drives the first end portion 110 of the flexible display panel 10 to be away from the second end portion 120 along the first direction Z, the flexible display panel 10 is gradually extended out from the pulling accommodating assembly 30, so that the flexible display panel 10 is unfolded to obtain a larger display area, and the size of the display area can be adjusted by controlling the pushing distance of the pushing assembly 20. Therefore, the display device provided by the embodiment of the application can realize automatic adjustment of the size of the display area.

It is understood that, in order to facilitate the control of the pulling accommodation assembly 30, one of the first support shaft 31 and the second support shaft 32 may be fixed in position, and the other may be movably disposed. Of course, it is within the scope of the present application that both the first support shaft 31 and the second support shaft 32 may be movably disposed.

Optionally, the position of the first support shaft 31 may be fixed, and the second support shaft 32 may move relative to the first support shaft 31, that is, the first support shaft 31 may be set as a fixed shaft whose position is fixed, and the second support shaft 32 is a movable shaft; in the process of unfolding the flexible display panel 10, the second support shaft 32 gradually approaches to the first support shaft 31, and then the distance between the second support shaft 32 and the first support shaft 31 is reduced, and in the process of accommodating the flexible display panel 10, the second support shaft 32 can be gradually away from the first support shaft 31, and then the distance between the second support shaft 32 and the first support shaft 31 is gradually increased.

With continued reference to fig. 1 and fig. 2, in some alternative embodiments, in the display device provided in the embodiments of the present application, the pushing assembly 20 may include a supporting rod 21 and a first transmission mechanism 22, the first end portion 110 of the flexible display panel 10 is fixed to the supporting rod 21, a length direction of the supporting rod 21 may be parallel to the extending direction X of the second supporting shaft 32 and the first supporting shaft 31, and the first transmission mechanism 22 is connected to the supporting rod 21 and is configured to drive the supporting rod 21 to move back and forth in the first direction Z, so that the flexible display panel 10 is accommodated in the pull accommodating assembly 30 or at least a portion of the flexible display panel 10 is released by the pull accommodating assembly 30.

Optionally, in the length direction of the supporting shaft, the first transmission mechanisms 22 may be disposed on both sides of the flexible display panel 10, and the two first transmission mechanisms 22 are respectively used for driving both ends of the supporting rod 21, so as to improve the stability of the flexible display panel 10 when being unfolded and stored. Of course, the number of the first transmission mechanisms 22 is not limited to this, and for example, the first transmission mechanisms 22 may be disposed only on one side or in the middle of the flexible display panel 10, and is also within the protection scope of the present application.

Optionally, the first transmission mechanism 22 may be a telescopic rod, and when the telescopic rod extends out, the support rod 21 and the first end portion 110 of the flexible display panel 10 are driven to move away from the drawing and accommodating assembly 30 along the first direction Z, so as to realize the unfolding of the flexible display panel 10; when the retractable rod is retracted, the supporting rod 21 and the first end 110 of the flexible display panel 10 are driven to approach the drawing and accommodating assembly 30 along the first direction Z, so that the flexible display panel 10 is accommodated in the drawing and accommodating assembly 30. Of course, the first transmission mechanism 22 may also be a screw mechanism, and the like, and is also within the scope of the present application.

Optionally, the pushing assembly 20 may further include a first power element, which provides power for the movement of the supporting rod 21 and the first end portion 110 of the flexible display panel 10. The first power element drives the support rod 21 and the first end 110 of the flexible display panel 10 to move through the first transmission mechanism 22, so as to realize the expansion and storage of the flexible display panel 10. It can be understood that, when the first transmission mechanism 22 is a telescopic rod, the first power element can drive the telescopic rod to extend and retract; when the first transmission mechanism 22 is a screw-threaded mechanism, the first power element may be a motor for driving the screw to rotate around the shaft.

In the display device provided in the embodiment of the present application, the second support shaft 32 and the first support shaft 31 of the pull accommodating component 30 can move relatively, and the relative movement direction of the first support shaft 31 and the second support shaft 32 is not particularly limited in the present application, alternatively, as shown in fig. 3, in order to save space and facilitate the setting of the display device, the second support shaft 32 and the first support shaft 31 can be relatively movably arranged in the first direction Z, that is, the second support shaft 32 can be close to or far away from the first support shaft 31 in the first direction Z.

In some optional embodiments, in the display device provided in this embodiment of the present application, the flexible display panel 10 may be disposed on the second support shaft 32 and the first support shaft 31 in a serpentine winding manner, that is, the flexible display panel 10 is supported by the second support shaft 32 and the first support shaft 31, and the flexible display panel 10 is alternately wound around the first support shaft 31 and the second support shaft 32, so that the second support shaft 32 and the first support shaft 31 are respectively located at two sides of the flexible display panel 10 in the thickness direction, a part of the flexible display panel 10 is wound in the inner winding manner, and a part of the flexible display panel 10 is wound out, which can reduce or even counteract interlayer slippage when the flexible display panel 10 is wound.

It is understood that the diameters of the first support shaft 31 and the second support shaft 32 may be the same or different. As an alternative embodiment, the diameters of the first support shaft 31 and the second support shaft 32 are the same, which enables the radii of the inner roll and the outer roll of the flexible display panel 10 to be the same.

The number of the first support shaft 31 and the second support shaft 32 is not limited in this application, and as an alternative embodiment, the draw storage assembly 30 may include a first support shaft 31 and a second support shaft 32, the first end portion 110 of the flexible display panel 10 is connected to the support rod 21, and the position of the second end portion 120 of the flexible display panel 10 may be fixed.

Alternatively, the first support shaft 31 may be located between the second support shaft 32 and the pushing assembly 20 in the second direction Y, such that the first end portion 110 of the flexible display panel 10 is connected to the support rod 21 after being guided by the first support shaft 31. Wherein the second direction Y may be perpendicular to the first direction Z and the extending direction X of the first and

second support shafts

31 and 32.

It can be understood that, when the first transmission mechanism 22 of the pushing assembly 20 is used to move the supporting rod 21 and the first end portion 110 of the flexible display panel 10 at the first speed V1, the second supporting shaft 32 needs to move at the second speed V2, and the relationship between the first speed V1 and the second speed V2 satisfies the relationship V1-2V 2.

In the same time, when the supporting rod 21 of the pushing assembly 20 drives the first end portion 110 of the flexible display panel 10 to extend (or retract) the first distance L1 in the first direction Z, the distance that the second supporting shaft 32 moves toward (or away from) the first supporting shaft 31 is 0.5L1, so that the flexible display panel 10 can be synchronously unfolded or retracted along with the pushing of the pushing assembly 20, and the tearing or the wrinkling of the flexible display panel 10 can be avoided.

As shown in fig. 4, in alternative embodiments, the first support shaft 31 and the second support shaft 32 may be provided in plurality, the first support shaft 31 and the second support shaft 32 are alternately arranged and spaced apart along the second direction Y, and the flexible display panel 10 may be alternately wound around the first support shaft 31 and the second support shaft 32. Wherein the second direction Y may be perpendicular to the first direction Z and the extending direction X of the first and

second support shafts

31 and 32.

It is understood that a plurality of the first and

second support shafts

31 and 32 are provided, the length of the flexible display panel 10 receivable by the pull receiving assembly 30 can be increased in the case where the movable distance of the first and

second support shafts

31 and 32 is fixed, and the movable distance of the first and

second support shafts

31 and 32 can be decreased in the case where the length of the flexible display panel 10 is fixed.

In some optional embodiments, in the display device provided in this embodiment, the pulling and accommodating assembly 30 may further include a second transmission mechanism, the second transmission mechanism drives the second supporting shaft 32 to be close to the first supporting shaft 31 during the unfolding process of the flexible display panel 10, and the second transmission mechanism drives the second supporting shaft 32 to be away from the first supporting shaft 31 during the accommodating process of the flexible display panel 10.

It is understood that the second transmission mechanism and the first transmission mechanism 22 may be linked to each other in order to enable the flexible display panel 10 to be unfolded or retracted synchronously with the movement of the supporting rod 21 so as to avoid the tearing or folding phenomenon of the flexible display panel 10.

As shown in fig. 3, the drawing and accommodating assembly 30 includes a first supporting shaft 31 and a second supporting shaft 32, and when the position of the second end 120 of the flexible display panel 10 is fixed, the first transmission mechanism 22 of the pushing assembly 20 drives the supporting rod 21 and the first end 110 of the flexible display panel 10 to move at a first speed V1, the second transmission mechanism drives the second supporting shaft 32 to move at a second speed V2, and the first speed V1 and the second speed V2 satisfy the relation V1-2V 2.

Optionally, the second transmission mechanism may be a telescopic rod, and when the telescopic rod extends out, the second support shaft 32 is driven to be away from the first support shaft 31 along the first direction Z, so as to accommodate the flexible display panel 10; when the telescopic rod retracts, the second supporting shaft 32 is driven to approach the first supporting shaft 31 along the first direction Z, so that the flexible display panel 10 can be gradually unfolded. Of course, the second transmission mechanism may also be a screw mechanism, and the like, and is also within the protection scope of the present application.

Optionally, the pull containment assembly 30 may further include a second powered member that powers the movement of the second support shaft 32.

When the first transmission mechanism 22 drives the first end portion 110 of the flexible display panel 10 to approach the drawing accommodating component 30, the second power element drives the second support shaft 32 to be away from the first support shaft 31 through the second transmission mechanism, so that the extended flexible display panel 10 is automatically accommodated in the drawing accommodating component 30, and the automatic accommodation of the flexible display panel 10 is realized. When the first transmission mechanism 22 drives the first end portion 110 of the flexible display panel 10 to be far away from the drawing and accommodating assembly 30, the second power element drives the second support shaft 32 to be close to the first support shaft 31 through the second transmission mechanism, which not only can effectively prevent the flexible display panel 10 from being stretched, but also can keep the flexible display panel 10 in a certain tensioning state during the unfolding process.

It can be understood that when the second transmission mechanism is a telescopic rod, the second power element can drive the telescopic rod to extend and retract; when the second transmission mechanism is a screw rod thread mechanism, the second power element can be a motor for driving the screw rod to rotate around the shaft.

Optionally, the pushing assembly 20 includes a first power element, and when the drawing and accommodating assembly 30 includes a second power element, both the first power element and the second power element may be electrically connected to the controller, and the controller controls the first power element and the second power element to operate simultaneously, so as to realize the linkage between the second transmission mechanism and the first transmission mechanism 22.

In some alternative embodiments, the first transmission mechanism 22 may include a first screw rod extending along the first direction Z and a first slider in threaded connection with the first screw rod, the support rod 21 is fixedly connected with the first slider, and when the first screw rod rotates, the first slider drives the support rod 21 to move in the first direction Z. The second transmission mechanism comprises a second screw rod extending along the first direction Z and a second sliding block in threaded connection with the second screw rod, the second supporting shaft 32 is fixedly connected with the second sliding block, and when the second screw rod rotates, the second supporting shaft 32 is driven by the second sliding block to move in the first direction Z.

It is understood that, when the first transmission mechanism 22 and the second transmission mechanism adopt the screw slider structure, in order to make the moving speed of the support rod 21 and the second support shaft 32 satisfy the relation V1-2V 2, the thread pitch of the first screw may be set to be the same as the thread pitch of the second screw and the rotation speed of the first screw is twice as high as that of the second screw, and the rotation speed of the first screw may also be set to be the same as that of the second screw and the thread pitch of the first screw is twice as high as that of the second screw.

It can be understood that, in order to enable the flexible display panel 10 to be unfolded or retracted synchronously with the movement of the supporting rod 21 so as to avoid the tearing or folding phenomenon of the flexible display panel 10, the second supporting shaft 32 needs to move simultaneously with the supporting rod 21, and the moving direction of the second supporting shaft 32 is opposite to the moving direction of the supporting rod 21. In order to make the moving direction of the second supporting shaft 32 opposite to the moving direction of the supporting rod 21, the rotating direction of the second screw rod can be set opposite to the rotating direction of the first screw rod, and the thread turning direction of the second screw rod is the same as the spiral turning direction of the first screw rod; alternatively, the rotation direction of the second screw may be the same as the rotation direction of the first screw, and the screw thread direction of the second screw may be opposite to the screw thread direction of the first screw.
