Abstract

A display device and an assembling method thereof are provided. The display device includes a display including an annular body, two flexible screens and a circuit board assembly disposed on the annular body. The two flexible screens are attached on an outer surface of the annular body, and opposite first ends of the two flexible screens are spliced with each other. The circuit board assembly is disposed in a mounting groove provided on the annular body and positioned between second ends of the two flexible screens. The circuit board assembly is electrically connected to both of the two flexible screens, and can drive the two flexible screens to display independently.

First claim

What is claimed is:

wherein the annular body is further provided with a fixation groove located at a side of the mounting groove between the second ends of the two flexible screens;
the display further comprises a battery disposed in the fixation groove, and the battery is electrically connected to the circuit board assembly.

2. The display device according to claim 1 , wherein the annular body is further provided with a positioning mark, and the positioning mark is configured to play a role of alignment when the two flexible screens are fixed on the annular body.

3. The display device according to claim 2 , wherein the positioning mark is a positioning groove or a marking line.

4. The display device according to claim 1 , wherein the display is provided with a charging port;
the display device further comprises a charging base, wherein the charging base is provided with a power port and a charging connector; the power port is configured to be connected to an external power source; and the charging connector is configured to be connected to the charging port when the display is placed on the charging base.

5. The display device according to claim 4 , wherein the display further comprises a bottom cover bracket disposed on the annular body and covering the mounting groove, a charging motherboard and a bottom cover disposed on the bottom cover bracket;
the circuit board assembly and the battery are electrically connected to the charging motherboard, the charging motherboard is provided with the charging port, and the bottom cover is disposed on an outer side of the charging motherboard and exposes the charging port.

6. The display device according to claim 5 , wherein the bottom cover bracket is provided with a fixation arm, and the fixation arm is pressed against the battery.

7. The display device according to claim 6 , wherein
when the charging base is connected to an eternal power source to charge the display, the battery is charged through the charging motherboard to supply power to the bottom plate through the charging motherboard after the battery is fully charged;
when the charging base is separated from the display, the battery supplies power to the bottom plate, and the bottom plate supplies power to the two flexible screens and the core board.

8. The display device according to claim 5 , wherein the circuit board assembly comprises a bottom plate and a core board disposed on the bottom plate and electrically connected to the bottom plate;
the two flexible screens and the charging motherboard are all electrically connected to the bottom plate.

9. The display device according to claim 8 , wherein the core board is provided with a heat conducting member, which is in contact with the bottom cover bracket, and the bottom cover bracket is made of a metal material.

10. The display device according to claim 5 , wherein the charging base comprises a base housing and a charging common board disposed in the base housing, wherein the charging common board is provided with the power port and the charging connector, and the charging connector extends out of the base housing and is configured to be inserted into and matched with the charging port.

11. The display device according to claim 10 , wherein the base housing comprises a bottom housing and an upper cover, an inner side of the upper cover is provided with a first magnet, and an inner side of the bottom cover is provided with a second magnet having a position corresponding to a position of the first magnet and attracting each other.

12. The display device of claim 11 , wherein an outer side of the upper cover is provided with a flexible grommet, and the flexible grommet is disposed around the charging connector.

13. The display device according to claim 11 , wherein a display lamp is further disposed on a side of the charging common board facing away from the upper cover.

14. The display device according to claim 11 , wherein a gap is formed between an edge of the charging common board and a side edge of the bottom housing, and a light guide post is disposed at the gap.

15. The display device according to claim 5 , wherein the display further comprises a screen cover disposed on the annular body and covering outer sides of the two flexible screens, and two ends of the screen cover are respectively positioned at two sides of the bottom cover.

16. The display device according to claim 15 , wherein portions of the screen cover corresponding to display regions of the two flexible screens are transparent.

17. The display device according to claim 15 , wherein the display further comprises a functional module disposed on an inner side of the screen cover and electrically connected to the circuit board assembly.

18. The display device according to claim 17 , wherein the functional module comprises one or more of a touch button, a WIFI antenna and an environmental sensor.

19. A method for assembling the display device according to claim 1 , and the method comprising:
attaching the two flexible screens on the outer surface of the annular body, and splicing the opposite first ends of the two flexible screens with each other;
