Abstract

A display device includes a first display panel, a second display panel opposite the first display panel, a frame positioned between the first display panel and the second display panel, a first opening formed on the frame and positioned on a lower back side of the first display panel, a second opening formed on the frame and positioned on an upper back side of the second display panel, a first printed circuit board (PCB) electrically connected to the first display panel and positioned in the first opening, and a second PCB electrically connected to the second display panel and positioned in the second opening.

First claim

What is claimed is:

1. A display device comprising:
a frame having first and second sides, wherein a first recess is provided on the first side, and a second recess is provided on the second side;
a first display panel provided on the first side;
a second display panel provided on the second side;
a first printed circuit board (PCB) electrically connected to the first display panel and positioned in the first recess;
a second PCB electrically connected to the second display panel and positioned in the second recess;
a first wire electrically connected to the first display panel and extending from a second long side of the first display panel, the first PCB electrically connected to the first wire;
a first cable electrically connected to the first PCB, placed between the first display panel and the frame, and extending outside of the first display panel;
a second wire electrically connected to the second display panel and extending from a first long side of the second display panel, the second PCB electrically connected to the second wire; and
a second cable electrically connected to the second PCB, placed between the second display panel and the frame, and extending outside of the second display panel.

2. The display device of claim 1 , wherein the first recess is positioned adjacent to a second long side of the first display panel, and wherein the second recess is positioned adjacent to a first long side of the second display panel.

3. The display device of claim 1 , further including:
a first controller installed on the frame, exposed to the outside, and positioned adjacent to an upper side of the first display panel; and
a second controller installed on the frame, exposed to the outside, and positioned adjacent to an upper side of the second display panel, wherein the first cable is electrically connected to the first controller, and the second cable is electrically connected to the second controller.

4. The display device of claim 3 , wherein the frame includes an upper frame extending from an upper part of each of the first display panel and the second display panel to the outside, wherein the first controller is positioned on one surface of the upper frame, and wherein the second controller is positioned on the other surface of the upper frame.

5. The display device of claim 1 , further including:
a first coupling member positioned between the first display panel and the frame, fixed to the frame, and contacting the first display panel; and
a second coupling member positioned between the second display panel and the frame, fixed to the frame, and contacting the second display panel.

6. The display device of claim 1 , further including:
a first coupling member positioned between the first display panel and the frame, fixed to the frame, and contacting the first display panel; and
a second coupling member positioned between the second display panel and the frame, fixed to the frame, and contacting the second display panel, wherein the first coupling member is formed in a portion of a left side of the frame and a portion of a right side of the frame, and wherein the first cable passes between the first coupling member and the second coupling member and is exposed to an outside of the first display panel.

7. The display device of claim 1 , wherein an area of the frame is substantially equal to an area of the first display panel or an area of the second display panel.

8. The display device of claim 1 , wherein the first and second recesses are formed as openings.

9. The display device of claim 1 , wherein the first and second sides are opposite each other.

10. The display device of claim 1 , wherein the first recess is positioned adjacent to a lower back side of the first display panel, and the second recess is positioned adjacent to an upper back side of the second display panel.

11. A display device comprising:
a display panel;
a frame positioned at a rear of the display panel and including an upper frame extending from an upper part of the display panel to an outside of the display panel;
a recess formed in the frame and positioned between the display panel and the frame;
a printed circuit board (PCB) electrically connected to the display panel and positioned in the recess;
a controller electrically connected to the PCB, installed on the upper frame;
a wire electrically connected to the display panel and extending from a side of the display panel, the PCB electrically connected to the wire; and
a cable electrically connected to the PCB, placed between the display panel and the frame, and extending outside of the display panel.

12. The display device of claim 11 , wherein the recess is positioned adjacent to an edge of the display panel.

13. The display device of claim 11 ,
wherein the controller is exposed to the outside of the display panel.

14. The display device of claim 11 , wherein the cable is electrically connected to the controller.

15. The display device of claim 11 , further including a coupling member positioned between the display panel and the frame, fixed to the frame, and contacting the display panel.

16. The display device of claim 15 , wherein the coupling member has a magnetic body or an adhesive strength.

17. The display device of claim 11 , further including:
a first coupling member positioned between the display panel and the frame, fixed to a portion of a left side of the frame, and contacting the display panel; and
a second coupling member positioned between the display panel and the frame, fixed to a portion of a right side of the frame, and contacting the display panel,
wherein the cable passes between the first coupling member and the second coupling member and extends to an outside of the display panel.

18. The display device of claim 11 , wherein the recess is formed as an opening.
