Abstract

A touch screen panel that that is less susceptible to malfunction by static electricity. The touch screen panel includes: a transparent substrate; sensing cells formed on the transparent substrate, comprising: first sensing cells connected in a first direction; and second sensing cells connected in a second direction intersecting with the first direction; and connecting patterns formed on the transparent substrate, comprising: first connecting patterns connecting the first sensing cells in the first direction, and second connecting patterns connecting the second sensing cells in the second direction; wherein the sensing cells include prominences extending toward adjacent ones of the sensing cells.

Claims

1. A touch screen panel comprising:

a transparent substrate;

sensing cells formed on the transparent substrate and comprising;

first sensing cells connected in a first direction; and

second sensing cells connected in a second direction intersecting with the first direction; and

connecting patterns formed on the transparent substrate and comprising;

first connecting patterns connecting the first sensing cells in the first direction; and

second connecting patterns connecting the second sensing cells in the second direction,

wherein the sensing cells include prominences extending toward adjacent ones of the sensing cells.

2. The touch screen panel as claimed in claim 1, wherein ends of the prominences include one or more convexo-concave patterns.

3. The touch screen panel as claimed in claim 2, wherein the convexo-concave patterns are formed in any one shape selected from a triangular shape, a saw-toothed shape, and a rectangular shape.

4. The touch screen panel as claimed in claim 2, wherein a distance between the convexo-concave patterns of adjacent ones of the sensing cells is within a range of 2 μ

m to 6 μ

m.

5. The touch screen panel as claimed in claim 1, wherein a shortest distance between the adjacent ones of the sensing cells is within a range of 2 μ

m to 6 μ

m.

6. The touch screen panel as claimed in claim 1, wherein the prominences are not formed at ends of the sensing cells that are connected to the connecting patterns.

7. The touch screen panel as claimed in claim 1, wherein the first connecting patterns and the second connecting patterns intersect with each other, and

wherein insulating layers are disposed between the first connecting patterns and the second connecting patterns.

8. The touch screen panel as claimed in claim 1, wherein the first sensing cells are separately patterned to have independent patterns, respectively, and

wherein the first sensing cells are connected in the first direction by the first connecting patterns positioned in layers different than layers having the first sensing cells.

9. The touch screen panel as claimed in claim 1, wherein the second sensing cells are integrally connected to the second connecting patterns.

10. The touch screen panel as claimed in claim 1, wherein the first sensing cells and the second sensing cells are alternatively spaced apart from each other in a same layer.

11. The touch screen panel as claimed in claim 1, further comprising dummy patterns formed between the prominences of the sensing cells.

12. The touch screen panel as claimed in claim 11, wherein the dummy patterns are formed apart from each other in a same layer as a layer having the sensing cells.

13. The touch screen panel as claimed in claim 11, wherein a shortest distance between the dummy patterns and the prominences of the sensing cells is within a range of 2 μ

m to 6 μ

m.

14. The touch screen panel as claimed in claim 11, wherein the dummy patterns are positioned in layers different than layer having the sensing cells, and

wherein insulating layers are disposed between the dummy patterns and the sensing cells.

15. The touch screen panel as claimed in claim 14, wherein the dummy patterns are formed to overlap ends of the prominences of the adjacent ones of the sensing cells.

16. The touch screen panel as claimed in claim 1, wherein the first sensing cells and the second sensing cells are alternately disposed in different layers, and

wherein insulating layers are disposed between the first sensing cells and the second sensing cells.

17. The touch screen panel as claimed in claim 16, wherein prominences of the first sensing cells are formed to overlap prominences of adjacent ones of the second sensing cells.

18. The touch screen panel as claimed in claim 1, wherein the prominences are formed at ends of the sensing cells not having the connecting patterns.
