Abstract

A touch sensing panel includes a plurality of first touch electrodes and a plurality of second touch electrodes in a touch sensing area to sense a touch, the plurality of first touch electrodes and the plurality of second touch electrodes are separated from each other. The touch sensing panel further includes a plurality of first connectors coupling the first touch electrodes arranged in a first direction and a plurality of second connectors coupling the second touch electrodes arranged in a second direction different from the first direction, a first connecting wire between a second touch electrode of the second touch electrodes and a first touch electrode of the first touch electrodes that are adjacent to each other, the first connecting wire being coupled to the first touch electrode or the corresponding first connectors, and a shield pattern adjacent to the first connecting wire and extending along the first connecting wire.

First claim

What is claimed is:

1. A touch sensing panel comprising:
a plurality of first touch electrodes and a plurality of second touch electrodes in a touch sensing area to sense a touch, the plurality of first touch electrodes and the plurality of second touch electrodes being separated from each other;
a plurality of first connectors coupling the first touch electrodes arranged along a first direction;
a plurality of second connectors coupling the second touch electrodes arranged along a second direction that is different from the first direction;
a first connecting wire between a second touch electrode of the second touch electrodes and a first touch electrode of the first touch electrodes that are adjacent to each other, the first connecting wire being coupled to the first touch electrode or a corresponding first connector; and
a shield pattern adjacent to the first connecting wire and extending along the first connecting wire,
wherein the shield pattern adjacent to the first connecting wire is closer to the first connecting wire than to the first touch electrode.

2. The touch sensing panel of claim 1 , wherein the shield pattern is between the second touch electrode and the first connecting wire.

3. The touch sensing panel of claim 2 , wherein the shield pattern is substantially parallel to the first connecting wire.

4. The touch sensing panel of claim 3 , wherein the shield pattern is at a same layer as at least one of the first touch electrode and the second touch electrodes.

5. The touch sensing panel of claim 4 , wherein the shield pattern is configured to transmit a constant voltage.

6. The touch sensing panel of claim 5 , further comprising a shield driving wire in a peripheral area of the touch sensing area and coupled to the shield pattern.
