Abstract

The present disclosure provides a display device including a display panel, a pair of supporting components, a rotating component, a first fixing part and a second fixing part. The display panel comprises: a first side and a second side which are opposite to each other, and the first side is fixedly connected to the first fixing part, and the second side is fixedly connected to the second fixing part. The pair of supporting components comprises: a first supporting component and a second supporting component which are opposite to each other. A first end of the first supporting component is fixedly connected to a first end of the rotating component, and a second end of the first supporting component is fixedly connected to a first end of the second fixing part at the second side of the display panel.

First claim

What is claimed is:

1. A display device, comprising: a display panel, a pair of supporting components, a rotating component, a first fixing part and a second fixing part; wherein
the first fixing part is fixedly connected to the rotating component;
the display panel comprises: a first side and a second side which are opposite to each other, and
the first side is fixedly connected to the first fixing part, and the second side is fixedly connected to the second fixing part;
the pair of supporting components comprises: a first supporting component and a second supporting component which are opposite to each other; a first end of the first supporting component is fixedly connected to a first end of the rotating component, and a second end of the first supporting component is fixedly connected to a first end of the second fixing part at the second side of the display panel; a first end of the second supporting component is fixedly connected to a second end of the rotating component, and a second end of the second supporting component is fixedly connected to a second end of the second fixing part at the second side of the display panel; and the first supporting component interacts with the second supporting component for supporting the display panel when the display panel is in an unfolded state; and
the rotating component is rotated under an external force to drive the display panel, the first supporting component and the second supporting component to move simultaneously, thereby folding or unfolding the display panel,
wherein the rotating component comprises a rotating shaft and a sleeve;
wherein the display device further comprises a driving component, which is connected to the rotating shaft and used for driving the rotating shaft to rotate, thereby unfolding or folding the display panel; and
wherein the sleeve is provided as a power supplying component, which is electrically coupled to the driving component and the display panel for supplying power to the driving component and the display panel.

2. The display device of claim 1 , wherein an orthographic projection of the first supporting component and an orthographic projection of the second supporting component on a plane parallel to the display panel do not overlap an orthographic projection of the display panel on the plane parallel to the display panel.

3. The display device of claim 1 , wherein the first side of the display panel is fixedly connected to the first fixing part by first upper and lower clamping blocks, and the second side of the display panel is fixedly connected to the second fixing part by second upper and lower clamping blocks.

4. The display device of claim 1 , wherein
the first end of the first supporting component is fixedly connected to a first end of the sleeve;
the first end of the second supporting component is fixedly connected to a second end of the sleeve; the first fixing part is fixedly connected to the sleeve; and the display panel is not abutted with the first supporting component and the second supporting component; and
an interference fit is formed between the rotating shaft and the sleeve, and the rotating shaft is rotated under the external force to drive the sleeve connected thereto to rotate, thereby unfolding or folding the display panel.

5. The display device of claim 4 , wherein the display device further comprises: a fixing shaft and a connecting component; and the fixing shaft is connected to the rotating shaft via the connecting component and used for being handheld.

6. The display device of claim 5 , wherein the display device further comprises: a cleaning component, which is fixed on the fixing shaft and used for keeping the surface of the display panel clean when the display panel is being folded.

7. The display device of claim 6 , wherein a material of the cleaning component comprises a conductive fiber.

8. The display device of claim 1 , wherein the power supplying component is further provided with switch units comprising a first switch unit, a second switch unit, and a third switch unit, and
the first switch unit, the second switch unit, and the third switch unit are used for controlling unfolding and folding of the display panel and supplying power to the display panel.

9. The display device of claim 1 , wherein the display device further comprises: a heat dissipation component, which is on a surface of the power supplying component and used for dissipating heat generated by the power supplying component.

10. The display device of claim 9 , wherein the heat dissipation component comprises:
a heat dissipation channel on the surface of the power supplying component; and
at least one heat dissipation member uniformly distributed on a surface of the heat dissipation channel.

11. The display device of claim 10 , wherein a shape of each of the at least one heat dissipation member comprises a rectangle, and a side of the heat dissipation member distal to the heat dissipation channel has a semispherical structure.

12. The display device of claim 9 , wherein a material of the heat dissipation component comprises graphene or carbon fiber.

13. The display device of claim 1 , wherein both of the first supporting component and the second supporting component have a silk-thread structure.

14. The display device of claim 1 , wherein a material of each of the first supporting component and the second supporting component comprises polyetheretherketone.
