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 around the touching area;
- a plurality of insulated protrusions in the touching area;
- an insulated frame in 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 along a second orientation and arranged between neighboring rows of the first conductive patterns, wherein the first conductive patterns are electrically insulated from the second conductive patterns;
- a plurality of connecting portions, wherein each connecting portion connects two neighboring first conductive patterns arranged in a row;
- a plurality of bridging members electrically connecting two neighboring second conductive patterns;
- and
- an overlapping region comprising a first region and a second region, wherein the overlapping region is the area that one of the bridging members overlaps one of the second conductive patterns and the bridging member is directly on the second conductive pattern in the first region and the insulated protrusion is directly on the second conductive pattern in the second region;
- wherein one of the insulated protrusions has a curved surface and covers one of the connecting portions;
- and
- wherein the length of the first region along the second orientation is longer than the length of the second region along the second orientation.
