Abstract

A touch screen panel includes a transparent substrate, sensing patterns on a first surface of the transparent substrate, and an insulating layer on the sensing patterns. A second surface of the transparent substrate opposite the first surface is adapted to be contacted by a contact object.

Claims

1. A touch screen panel, comprising:

a transparent substrate;

sensing patterns on a first surface of the transparent substrate; and

an insulating layer on the sensing patterns,

wherein a second surface of the transparent substrate opposite the first surface is adapted to be contacted by a contact object.

2. The touch screen panel as claimed in claim 1, further comprising:

a ground electrode layer on the insulating layer; and

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

3. The touch screen panel as claimed in claim 2, further comprising a buffer film between the first adhesive layer and the ground electrode layer.

4. The touch screen panel as claimed in claim 3, further comprising:

a second adhesive layer on the second surface of the transparent substrate; and

an icon sheet on the second adhesive layer.

5. The touch screen panel as claimed in claim 4, wherein the buffer film comprises a polymer, and wherein the icon sheet comprises the same polymer as the buffer film.

6. The touch screen panel as claimed in claim 1, further comprising a buffer film on the insulating layer.

7. The touch screen panel as claimed in claim 6, wherein the buffer film comprises a polymer comprising polyethylene terephthalate (PET).

8. The touch screen panel as claimed in claim 1, further comprising:

an adhesive layer on the second surface of the transparent substrate; and

an icon sheet on the adhesive layer.

9. The touch screen panel as claimed in claim 8, wherein the icon sheet comprises a polymer.

10. The touch screen panel as claimed in claim 1, wherein the sensing patterns comprise first sensing patterns and second sensing patterns on different layers.

11. The touch screen panel as claimed in claim 10,

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

wherein the second sensing patterns are coupled to each other in a second direction that crosses the first direction.

12. The touch screen panel as claimed in claim 11, wherein the first direction is substantially a column direction, and wherein the second direction is substantially a row direction.

13. The touch screen panel as claimed in claim 10, wherein the first sensing patterns are X sensing patterns coupled to adjacent X sensing patterns in a column direction, and wherein the second sensing patterns are Y sensing patterns coupled to adjacent Y sensing patterns in a row direction.

14. The touch screen panel as claimed in claim 1, wherein when a contact object contacts the second surface of the transparent substrate at a contact position, the touch screen panel is configured to generate an electric signal including information of the contact position corresponding to a change in electrostatic capacitance at the contact position.

15. The touch screen panel as claimed in claim 1, wherein the touch screen panel does not include an additional surface adapted to be contacted by a contact object.
