Touch screen panel
A touch screen panel that including a substrate having an active area and a non-active area positioned outside the active area, and first and second sensing electrodes formed over the active area. The first sensing electrodes are connected along a first direction, and the second sensing electrodes are connected along a second direction that intersects the first direction, and outside wiring lines are formed in the non-active area to connect the first and second sensing electrodes to an external driving circuit in units of lines and have at least one of slits that cross insides of the outside wiring lines so that widths of conductive paths are reduced in partial sections.
1. A touch screen panel, comprising:
a substrate comprising an active area and a non-active area positioned outside the active area;
first and second sensing electrodes formed on the active area, wherein the first sensing electrodes are connected along a first direction, and wherein the second sensing electrodes are connected along a second direction that intersects the first direction; and
outside wiring lines formed in the non-active area to connect the first and second sensing electrodes to an external driving circuit and having at least one slit that crosses inside of at least one of the outside wiring lines so that a width of a conductive path portion through which current flows is reduced in a partial section of the at least one of the outside wiring lines;
wherein:
the at least one of the outside wiring lines is divided into the conductive path portion and a strip pattern by the slit, in the partial section;
the strip pattern is formed of a conductive material and integrally connected to the conductive path portion; and
an end of the strip pattern is electrically floated so that current does not flow through the strip pattern.
2. The touch screen panel as claimed in claim 1 , wherein:
the at least one slit comprises:
a first slit formed in one of the outside wiring lines closer to the active area; and
a second slit formed in another one of the outside wiring lines disposed away from the active area; and
the first slit has a greater area than the second slit.
3. The touch screen panel as claimed in claim 2 , wherein:
each slit comprises a first slit portion extended in a direction that intersects a longitudinal direction of a corresponding outside wiring line and opens to an outside edge of the outside wiring line, and a second slit portion extended from the first slit portion in parallel with the longitudinal direction of the outside wiring line; and
the strip pattern is surrounded by the first slit portion, the second slit portion, and the outside edge of the outside wiring line.
4. The touch screen panel as claimed in claim 3 , wherein:
the strip pattern comprises a first line contacted to the first slit portion, a second line contacted to the second slit portion, and a third line extended from the outside edge of the outside wiring line; and
the first line and the third line are connected to both end portions of the second line, respectively.
5. The touch screen panel as claimed in claim 2 , wherein the one of the outside wiring line closer to the active area has a length less than a length of the another one of the outside wiring lines disposed away from the active area.
6. The touch screen panel as claimed in claim 3 , wherein the first slit portion of each slit crosses the outside wiring line.
7. The touch screen panel as claimed in claim 1 , wherein the first sensing electrodes and the second sensing electrodes are alternately arranged so as not to overlap with each other.
8. The touch screen panel as claimed in claim 1 , wherein:
the outside wiring lines have different lengths; and
the number of slits is increased as lengths of the outside wiring lines are smaller.
9. The touch screen panel as claimed in claim 3 , wherein:
the outside wiring lines have different lengths; and
a length of the second slit portion is increased as lengths of the outside wiring lines are smaller.
10. The touch screen panel as claimed in claim 1 , wherein the strip pattern is extended to parallel in a longitudinal direction of the outside wiring lines.
11. The touch screen panel as claimed in claim 10 , wherein the strip pattern formed in the outside wiring line closer to the active area has a greater area than the strip pattern formed in the outside wiring line away from the active area.
12. The touch screen panel as claimed in claim 1 , wherein the outside wiring lines have substantially a uniform width in all sections.
13. The touch screen panel as claimed in claim 1 , wherein the outside wiring lines include a low resistance metal material.
14. The touch screen panel as claimed in claim 13 , wherein the low resistance metal material includes at least one selected from the group consisting of Mo, Ag, Ti, Cu, Al, and Mo/Al/Mo.
15. The touch screen panel as claimed in claim 1 , wherein:
the outside wiring lines comprise a first outside wiring line and a second outside wiring line positioned closer to the active area than the first outside wiring line; and
the slit formed in the second outside wiring line has a greater length than the slit formed in the first outside wiring line.
16. The touch screen panel as claimed in claim 1 , wherein:
the outside wiring lines comprise a first outside wiring line and a second outside wiring line positioned closer to the active area than the first outside wiring line; and
the number of slits formed in the second outside wiring line is greater than the number of slits formed in the first outside wiring line.
