Abstract
A method of fabricating a capacitance touch panel module includes forming a plurality of first conductive patterns on a substrate comprising a touching area and a peripheral area along a first orientation, a plurality of second conductive patterns along a second orientation, and a plurality of connecting portions in the touching area; forming a plurality of insulated protrusions, in which each insulated protrusion covering one connecting portion, and forming an insulated frame on the peripheral area; and forming a bridging member on each insulated protrusion.
Claims13
A capacitance touch panel, comprising:
- a substrate comprising a touching area and a peripheral area, wherein the peripheral area is around the touching area;
- a plurality of insulated protrusions in the touching area;
- an insulated frame corresponding to the peripheral area;
- a plurality of first conductive patterns arranged in a plurality of rows along a first orientation;
- a plurality of second conductive patterns arranged in a plurality of columns along a second orientation, wherein the second conductive patterns are electrically insulated from the first conductive patterns;
- and
- a plurality of connecting portions, wherein each connecting portion connects two neighboring first conductive patterns arranged in a row;
- a plurality of bridging members, wherein each bridging member connects two neighboring second conductive patterns in a column;
- and
- an overlapping region, wherein the overlapping region is the area that one of the connecting portions overlaps one of the insulated protrusions;
- wherein one of the insulated protrusions has a curved surface, and covers one of the connecting portions;
- and
- wherein one of the bridging members along the second orientation is longer than the overlapping region along the first orientation.
