Abstract

A touch screen panel includes a substrate having high transmittance, sensing patterns on a first surface of the substrate, a film on the sensing patterns, and metal patterns and position detecting lines on the film and electrically coupled to the sensing patterns, wherein a second surface of the substrate opposite the first surface is adapted to be contacted by a contact object.

Claims

1. A touch screen panel, comprising:

a substrate having high transmittance;

sensing patterns on a first surface of the substrate;

a film on the sensing patterns; and

metal patterns and position detecting lines on the film and electrically coupled to the sensing patterns,

wherein a second surface of the 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:

an insulating layer between the sensing patterns and the film; and

a first adhesive layer between the insulating layer and the film.

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

a second adhesive layer on the film; and

a ground electrode layer on the second adhesive layer.

4. The touch screen panel as claimed in claim 1, wherein the film comprises polyethylene terephthalate (PET).

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

6. The touch screen panel as claimed in claim 5,

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.

7. The touch screen panel as claimed in claim 6, wherein the first direction is substantially a column direction, and wherein the second direction is substantially a row direction.

8. The touch screen panel as claimed in claim 5, wherein the first sensing patterns comprise X sensing patterns coupled to adjacent X sensing patterns in a column direction, and wherein the second sensing patterns comprise Y sensing patterns coupled to adjacent Y sensing patterns in a row direction.

9. The touch screen panel as claimed in claim 1, wherein the metal patterns are arranged corresponding to edge regions of the sensing patterns, and are arranged such that the sensing patterns are electrically coupled to corresponding ones of the position detecting lines in the first direction or the second direction.

10. The touch screen panel as claimed in claim 9, wherein the metal patterns are formed on the film prior to arranging the film on the sensing patterns.

11. The touch screen panel as claimed in claim 1, wherein the metal patterns and the position detecting lines electrically couple the sensing patterns to an external driving circuit.

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

13. The touch screen panel as claimed in claim 1, wherein the sensing patterns are formed on the substrate by utilizing an exposing and developing process, and wherein the metal patterns and the position detecting lines are formed on the film before the film is attached to the touch screen panel.

14. 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.

15. The touch screen panel as claimed in claim 1, wherein the substrate comprises glass.
