Abstract

A touch screen panel comprises a glass substrate having a display area and a non-display area, a plurality of sense patterns on the display area, a plurality of metal pads on a periphery of the display area and on the non-display area, a plurality of sense lines on the non-display area, and dummy patterns on an area between the plurality of sense lines on the non-display area. The non-display area is outside a periphery of the display area. Each of the plurality of the sense lines is coupled to one of the plurality of metal pads. The display area and non-display area of the glass substrate respectively correspond to a display area and non-display area of an image display device to which the touch screen panel is provided.

Claims

1. A touch screen panel, comprising:

a glass substrate having a display area and a non-display area, the non-display area being outside a periphery of the display area, the display area corresponding to a display area of an image display device to which the touch screen panel is provided, and the non-display area corresponding to a non-display area of the image display device;

a plurality of sense patterns on the display area of the glass substrate;

a plurality of metal pads on a periphery of the display area of the glass substrate and on the non-display area of the glass substrate;

a plurality of sense lines on the non-display area of the glass substrate, each of the plurality of the sense lines being coupled to one of the plurality of metal pads; and

dummy patterns on areas between the plurality of sense lines on the non-display area of the glass substrate.

2. The touch screen panel as claimed in claim 1, wherein the dummy patterns are made of the same material as the sense lines.

3. The touch screen panel as claimed in claim 1, wherein each of the dummy patterns is of an island shape, and is not electrically coupled to the sense lines.

4. The touch screen panel as claimed in claim 1, wherein the sense patterns include an X sense pattern and a Y sense pattern arranged on different layers.

5. The touch screen panel as claimed in claim 4, wherein

the X pattern includes a plurality of first units,

each of the first units includes a plurality of first sense patterns arranged in a first direction,

the Y pattern includes a plurality of second units,

each of the second units includes a plurality of second sense patterns arranged in a second direction different from the first direction,

adjacent first sense patterns in each of the first units are electrically coupled to each other in the first direction, and

adjacent second sense patterns in each of the second units are electrically coupled to each other in the second direction.
