Abstract

A display device including a touch screen panel and method of manufacturing the same are disclosed. In one aspect, the display device includes a first substrate including a display region and a peripheral region, a light-emitting structure formed over the first substrate, and a second substrate formed over the light-emitting structure. The display device also includes a touch screen panel formed over the second substrate and a touch screen panel-flexible printed circuit (TSP-FPC) board at least partially overlapping the peripheral region, wherein the TSP-FPC board is electrically connected to the touch screen panel. The display device further includes a protective member substantially covering the display region and the peripheral region. A top structure is interposed between the TSP-FPC board and the protective member in the peripheral region and a bottom structure interposed between the TSP-FPC board and the first substrate in the peripheral region.

Claims (51)

1. A display device, comprising:

a first substrate including a display region and a peripheral region;

a light-emitting structure formed over the first substrate;

a second substrate formed over the light-emitting structure;

a touch screen panel formed over the second substrate;

a touch screen panel-flexible printed circuit (TSP-FPC) board at least partially overlapping the peripheral region, wherein the TSP-FPC board is electrically connected to the touch screen panel;

a polarizer formed over the touch screen panel in the display region;

a resin layer formed over the polarizer;

a protective member formed over the resin layer, wherein the protective member substantially covers the display region and the peripheral region;

a top structure interposed between the TSP-FPC board and the protective member in the peripheral region; and

a bottom structure interposed between the TSP-FPC board and the first substrate in the peripheral region.

2. The device of claim 1 , wherein each of the top structure and the bottom structure comprises a buffer member, a supporting member, or a spacer.

3. The device of claim 1 , wherein the top structure is configured to maintain the TSP-FPC board at a predetermined distance from the protective member.

4. The device of claim 1 , wherein the top structure is formed on an upper surface of the TSP-FPC board and contacts a lower surface of the protective member.

5. The device of claim 1 , wherein the top structure is formed on an upper surface of the TSP-FPC board and is spaced apart from a lower surface of the protective member.

6. The device of claim 1 , wherein the bottom structure is configured to maintain the TSP-FPC board at a predetermined distance from the first substrate.

7. The device of claim 1 , wherein the bottom structure is formed on a lower surface of the TSP-FPC board and contacts an upper surface of the first substrate.

8. The device of claim 1 , wherein the bottom structure is formed on a lower surface of the TSP-FPC board and is spaced apart from an upper surface of the first substrate.

9. The device of claim 1 , wherein at least one of the top structure and the bottom structure comprises a plurality of layers.

10. The device of claim 9 , wherein each of the layers is a polyethylene terephthalate (PET) layer, a polyimide (PI) layer, or a silicon rubber layer.

11. The device of claim 9 , wherein the at least one of the top structure and the bottom structure further comprises an adhesive tape interposed between the layers.

12. A method of manufacturing a display device, comprising:

providing a first substrate including a display region and a peripheral region;

forming a light-emitting structure over the first substrate;

forming a second substrate over the light-emitting structure;

forming a touch screen panel over the second substrate;

providing a touch screen panel-flexible printed circuit (TSP-FPC) board;

forming a top structure on an upper surface of the TSP-FPC board;

forming a bottom structure on a lower surface of the TSP-FPC board;

attaching the TSP-FPC board to the first substrate such that the top and bottom structures are located in the peripheral region;

electrically connecting the TSP-FPC board to the touch screen panel;

forming a polarizer over the touch screen panel in the display region;

forming a resin layer over the polarizer; and

forming a protective member over the resin layer, wherein the protective member substantially covers the display region and the peripheral region.

13. The method of claim 12 , wherein each of the top structure and bottom structure comprises a buffer member, a supporting member, or a spacer;

wherein the top structure is configured to maintain the TSP-FPC board at a predetermined distance from the protective member; and

wherein the bottom structure is configured to maintain the TSP-FPC board at a predetermined distance from the first substrate.

14. The method of claim 12 , wherein the forming of at least one of the top structure and the bottom structure comprises forming a plurality of layers and wherein each of the layers is a polyethylene terephthalate layer, a polyimide layer, or a silicon rubber layer.

15. The method of claim 14 , wherein the forming of the layers further comprises forming an adhesive material between the layers.

16. A display device, comprising:

a first substrate including a display area and a peripheral area;

a light-emitting structure formed over the first substrate in the display area;

a touch screen panel formed over the light-emitting structure;

a second substrate formed over the touch screen panel and substantially covering the display area and the peripheral area;

a touch screen panel-flexible printed circuit (TSP-FPC) board electrically connected to the touch screen panel;

a first spacer formed in the peripheral area and interposed between the TSP-FPC board and the first substrate; and

a second spacer formed in the peripheral area and interposed between the TSP-FPC board and the second substrate.

17. The display device of claim 16 , wherein the first spacer is configured to maintain a first distance between the TSP-FPC board and the first substrate and wherein the second spacer is configured to maintain a second distance between the TSP-FPC board and the second substrate.

18. The display device of claim 17 , wherein the second distance is greater than the first distance.

19. The display device of claim 16 , wherein the second spacer is formed on an upper surface of the TSP-FPC board and is spaced apart from a lower surface of the second substrate.

20. The display device of claim 16 , wherein the first spacer is formed on a lower surface of the TSP-FPC board and is spaced apart from an upper surface of the first substrate.
