Abstract

Official abstract text for this publication.

A touch sensor includes a substrate having at least one bending portion; and a sensing pattern on the substrate, the sensing pattern including a first pattern and a second pattern, the first pattern being arranged along a first direction parallel to a surface of the substrate, the second pattern being arranged along a second direction, the second direction being parallel to the surface of the substrate and crossing the first direction. The second pattern includes unit patterns isolated from each other, and a bridge electrode electrically connecting neighboring unit patterns of the unit patterns. The bridge electrode extends along the same direction as a bending direction of the bending portion.

First claim

Opening claim text (preview).

What is claimed is: 1 . A touch sensor, comprising: a substrate having at least one bending portion; a sensing pattern on the substrate, the sensing pattern including a first pattern and a second pattern, the first pattern being arranged along a first direction parallel to a surface of the substrate, the second pattern being arranged along a second direction, the second direction being parallel to the surface of the substrate and crossing the first direction, the second pattern including unit patterns isolated from each other; and a bridge electrode electrically connecting neighboring unit patterns of the unit patterns, the bridge electrode extending along a direction the same as a bending direction of the bending portion. 2 . The touch sensor of claim 1 , wherein the first pattern includes a connecting portion and unit patterns electrically connected to each other via the connecting portion. 3 . The touch sensor of claim 1 , wherein a bending angle of the bending portion is greater than 0° and less than 180°. 4 . The touch sensor of claim 1 , wherein the bridge electrode includes at least one selected from a group consisting of indium tin oxide (ITO), indium zinc oxide (IZO), indium zinc tin oxide (IZTO), aluminum zinc oxide (AZO), gallium zinc oxide (GZO), fluorine tin oxide (FTO), ITO-silver (Ag)-ITO, IZO-Ag-IZO, IZTO-Ag-IZTO and AZO-Ag-AZO. 5 . The touch sensor of claim 1 , wherein the bridge electrode includes at least one selected from a group consisting of molybdenum, silver, aluminum, copper, palladium, gold, platinum, zinc, tin, titanium and an alloy thereof. 6 . The touch sensor of claim 2 , wherein a line width of the bridge electrode is from 1.5% to 200% of the connecting portion included in the first pattern. 7 . The touch sensor of claim 1 , wherein a thickness of the bridge electrode is from 20% to 1,300% of a thickness of the unit pattern included in the second pattern. 8 . The touch sensor of claim 1 , wherein an angle between the bridge electrode and the first direction is greater than 0° and not greater than 90°. 9 . The touch sensor of claim 2 , further comprising an insulation layer formed on the connecting portion of the first pattern. 10 . A touch screen panel comprising the touch sensor of claim 1 . 11 . An image display device comprising the touch screen panel of claim 10 .
