Abstract
The present disclosure provides a touch sensing device and a method for fabricating the same. The touch sensing device comprises a touch panel and a flexible printed circuit board, wherein the touch panel comprises a first bonding mark and the flexible printed circuit board has a bonding surface bonded to the touch panel and has a non-bonding surface. The flexible printed circuit board comprises a second bonding mark disposed on the non-bonding surface. The second bonding mark and the first bonding mark have a relationship of contraposition.
Claims15
A touch sensing device, comprising:
- a touch panel comprising a first bonding mark;
- and
- a flexible printing circuit board having a bonding surface bonded to the touch panel and a non-bonding surface, wherein the flexible printing circuit board further comprises a second bonding mark disposed on the non-bonding surface, and wherein the second bonding mark and the first bonding mark form a relationship of contraposition, wherein the first bonding mark has at least one contraposition portion, and wherein the contraposition portion is uncovered and exposed from the flexible printing circuit board to perform a contraposition benchmark to the second bonding mark, upon bonding the flexible printing circuit board to the touch panel,
- wherein the first bonding mark comprises a first base part and at least two first extending parts, wherein the second bonding mark comprises a second base part and at least two second extending parts, and wherein one end of each of the second extending parts is aligned at a side edge of the flexible printing circuit board, wherein each of the two first extending parts has the contraposition portion, and wherein the contraposition portion is aligned with the end of the second extending part at the side edge of the flexible printing circuit board, upon bonding the flexible printing circuit to the touch panel, and
- wherein the first extending parts and the second extending parts have the same width, and wherein the length of the first extending parts is greater than the length of the second extending parts for defining the contraposition portion.

A method of fabricating a touch sensing device, comprising the steps of:
- providing a touch panel and a flexible printing circuit board, wherein the touch panel comprises a first bonding mark, the flexible printing circuit board has a bonding surface used for bonding to the touch panel and a non-bonding surface, wherein the flexible printing circuit board further comprises a second bonding mark disposed on the non-bonding surface, wherein the first bonding mark has at least one contraposition portion;
- and
- bonding the bonding surface of the flexible printing circuit board to the touch panel according to the contraposition between the first bonding mark and the second bonding mark, wherein the contraposition portion is uncovered and exposed from the flexible printing circuit board to perform a contraposition benchmark to the second bonding mark upon bonding the flexible printing circuit board to the touch panel,
- wherein the first bonding mark comprises a first base part and at least two first extending parts, wherein the second bonding mark comprises a second base part and at least two second extending parts, and wherein one end of each of the second extending parts is aligned at a side edge of the flexible printing circuit board, wherein each of the two first extending parts has the contraposition portion, and wherein the step of bonding the bonding surface of the flexible printing circuit board to the touch panel further comprises aligning the contraposition portion with the end of the second extending part at the side edge of the flexible printing circuit board, and
- wherein the first extending parts and the second extending parts have the same width, and wherein the length of the first extending parts is greater than the length of the second extending parts for defining the contraposition portion.
