Abstract

A touch screen panel is provided. The touch screen panel includes a plurality of sensing patterns formed in a display region of a transparent substrate, metal patterns arranged in a column or row in a region outside the display region and at one end of the sensing patterns, and auxiliary metal pattern arranged in a column or a row in a region outside the display region and at another end of the sensing patterns. The transparent substrate comprises a surface over which the sensing patterns are formed and disposed in a direction facing a display panel, and another surface on which a window is formed over said metal patterns and auxiliary metal patterns, said another surface disposed in a direction facing a contact object.

Claims

1. A touch screen panel, comprising:

a plurality of sensing patterns formed in a display region of a transparent substrate;

metal patterns arranged in a column or row in a region outside the display region and at one end of the sensing patterns; and

auxiliary metal patterns arranged in a column or a row in a region outside the display region and at another end of the sensing patterns,

wherein the transparent substrate comprises a surface over which the sensing patterns are formed and disposed in a direction facing a display panel, and another surface on which a window is formed over said metal patterns and auxiliary metal patterns, said another surface disposed in a direction facing a contact object.

2. The touch screen panel of claim 1, further comprising a matrix positioned in the non-display region, wherein the matrix comprises a portion that includes a logo engraved in the portion.

3. The touch screen panel of claim 2, wherein the metal patterns or the auxiliary metal patterns are formed over a surface of the black matrix and are exposed on the logo.

4. The touch screen panel of claim 1, further comprising:

an insulating layer over the sensing patterns; and

a ground electrode layer over the insulating layer; and

a first adhesive layer interposed between the ground electrode layer and the insulating layer.

5. The touch screen panel of claim 4, further comprising a buffer film between the first adhesive layer and the ground electrode layer.

6. The touch screen panel of claim 1, wherein the sensing patterns comprise X sensing patterns formed on one layer and Y sensing patterns formed on another layer.

7. The touch screen panel as claimed in claim 6,

wherein the X sensing patterns are patterned to be coupled to each other in a first direction, and

wherein the Y sensing patterns are patterned to be coupled to each other in a second direction that intersects the first direction.

20. A method of manufacturing the touch screen panel of claim 1, comprising forming the metal patterns or the auxiliary metal pattern in an outer region of the transparent substrate as a frame or logo of the window.

8. A touch screen panel comprising:

a substrate comprising a first surface and a second surface;

a plurality of sensors disposed over the first surface in a display region of the substrate; and

a matrix disposed over the first surface in a non-display region of the substrate;

wherein the second surface comprises a contact surface over the plurality of sensors and a window surface over the matrix.

9. The touch screen panel of claim 8, wherein the substrate is transparent.

10. The touch screen panel of claim 8, further comprising metal structures disposed over the matrix over the first surface.

11. The touch screen panel of claim 10, further comprising an insulating layer disposed over the first surface, wherein at least a portion of the sensors and at least a portion of the metal structures are formed within the insulating layer.

12. The touch screen panel of claim 11, further comprising an adhesive layer disposed over the insulating layer.

13. The touch screen panel of claim 12, further comprising a ground electrode layer disposed over the adhesive layer.

14. A touch screen panel comprising:

a transparent substrate;

a plurality of sensors disposed over a surface of the substrate on a region of the substrate; and

a matrix disposed over the surface on another region of the substrate;

wherein the region with the sensors provides a contact region and the region with the matrix provides a frame region.

15. The touch screen panel of claim 14, wherein the contact and frame regions are located on a surface of the substrate opposite to the surface over which the sensors and the matrix are disposed.

16. The touch screen panel of claim 14, wherein the plurality of sensors comprises a first group of sensors arranged in a first direction and a second group of sensors arranged in a second direction that intersects the first direction.

17. The touch screen panel of claim 16, wherein the first group of sensors is coupled to a first group of metal structures disposed over the matrix, and the second group of sensors is coupled to a second group of metal structures disposed over the matrix.

18. The touch screen panel of claim 17, wherein the first group of sensors and the metal structures are formed on an insulating layer.

19. The touch screen panel of claim 14, wherein the plurality of sensors comprises a first group of sensors formed on a first insulating layer and a second group of sensors formed on a second insulating layer.
