Abstract

Embodiments of the present application provide a display device, which solves the problems that it is difficult for the single-screen display to be realized non-integrated touch and display, that the separation operation cannot be realized so that today's increasingly diverse application requirements cannot be satisfied. The display device according to the present application includes: a display screen; at least one touch screen communicatively coupled to the display screen; and a controller configured to execute the following instructions: adjusting a display content of the display screen in communication with the touch screen according to an input instruction of the touch screen.

First claim

What is claimed is:

1. A display device, comprising:
a display screen;
at least one touch screen having a communication connection with the display screen;
at least two curved surfaces, wherein the display screen is disposed on at least one of the at least two curved surfaces; the touch screen is disposed on at least one of the at least two curved surfaces;
and
a controller executing following instructions: according to an input instruction from the touch screen, adjusting a display content of the display screen having a communication connection with the touch screen;
wherein the at least one touch screen is external to the display screen, and the display device allows a user to remotely manipulate the display screen by means of the at least one touch screen;
wherein the at least two curved surfaces comprise a display screen subassembly and a touch screen subassembly: and
wherein a shape of the display screen subassembly is a concave curved shape, a shape of the touch screen subassembly is a convex curved shape.

2. The display device according to claim 1 , wherein the display screen has one or both of a touch-control function and a display function.

3. The display device according to claim 1 , wherein the touch screen has one or both of a. touch-control function and a display function.

4. The display device according to claim 1 , wherein the touch screen is a transparent structure.

5. The display device according to claim 1 , wherein a shape of the display screen is a curved surface or a flat, and a shape of the touch screen is a curved surface or a flat.

6. The display device according to claim 1 , wherein the at least two curved surfaces display separately or simultaneously.

7. The display device according to claim 6 , wherein when the at least two curved surfaces display simultaneously, picture information displayed by the at least two curved surfaces is same or different.

8. The display device according to claim 1 , wherein the display screen is a flexible display screen.

9. The display device according to claim 1 , further comprising: a first support subassembly, a bottom cover, a first frame, a top cover, a second support subassembly and a second frame: wherein
the first support subassembly and the bottom cover are fixed by a first screw;
the first frame and the top cover are fixed by a second screw; and
the second frame and the top cover are fixed by a third screw.

10. The display device according to claim 9 , wherein the top cover comprises a hollowed-out area and a non-hollowed area, a projection of the display screen subassembly on the top cover corresponds to the hollowed-out area, and a projection of the touch screen subassembly on the top cover corresponds to the non-hollowed area.

11. The display device according to claim 9 , wherein the display screen subassembly fits the first support subassembly;
the first support subassembly fits the top cover;
the touch screen subassembly fits the second support subassembly; and
the second frame fits the second support subassembly.

12. The display device according to claim 9 , further comprising a printed circuit board, disposed between the bottom cover and the first support sub assembly.

13. The display device according to claim 12 , wherein the printed circuit board and the first support subassembly are fixed by a fourth screw.
