Touch panel having electrodes and routings on single layer
A touch panel includes electrodes and routings disposed on a single conductive layer. The electrodes and routings are connected to drivers and sensors to sense mutual capacitance changes induced by a touch among the electrodes. The touch panel includes a first electrode, a second electrode, and a first routing connected to the first electrode. The second electrode includes two sub-electrodes respectively disposed at two sides of the first routing. The first electrode has a first jigsaw section, and the second electrode has a second jigsaw section mutually intervening with the first jigsaw section in an insulated manner.
1. A touch panel, comprising:
a first electrode, being “E”-shaped, disposed at a conductive layer, wherein a border of the first electrode has two jigsaw sections;
a second electrode, being “E”-shaped, disposed at the conductive layer and insulated from the first electrode, wherein a border of the second electrode has two jigsaw sections;
a third electrode, being “E”-shaped, disposed at the conductive layer and insulated from the first electrode and the second electrode, wherein a border of the third electrode has two jigsaw sections; and
a fourth electrode, being “E”-shaped, disposed at the conductive layer and insulated from the first electrode, the second electrode and the third electrode, wherein a border of the fourth electrode has two jigsaw sections,
wherein one jigsaw section of the first electrode intervenes with one jigsaw section of the third electrode with an insulation gap in between, another jigsaw section of the third electrode intervenes with one jigsaw section of the second electrode with an insulation gap in between, another jigsaw section of the second electrode intervenes with one jigsaw section of the fourth electrode with an insulation gap in between, and
wherein the first electrode and the second electrode are connected to one or more drivers, and the third electrode and the fourth electrode are connected to one or more sensors.
2. The touch panel according to claim 1 , further comprising:
a first routing, arranged on the conductive layer and connected to the first electrode;
a second routing, arranged on the conductive layer and connected to the second electrode;
a third routing, arranged on the conductive layer and connected to the third electrode; and
a fourth routing, arranged on the conductive layer and connected to the fourth electrode,
wherein the first and third routings are extended into a pad region via a first side of a touch control region, and the second and fourth routings are extended into the pad region via a second side of the touch control region that is opposite to the first side of the touch control region.
3. The touch panel according to claim 1 , further comprising:
a first routing, arranged on the conductive layer and connected to the first electrode;
a second routing, arranged on the conductive layer and connected to the second electrode;
a third routing, arranged on the conductive layer and connected to the third electrode; and
a fourth routing, arranged on the conductive layer and connected to the fourth electrode;
wherein the first, second, third and fourth routings are extended into a pad region via a same side of a touch control region.
