A touch sensor includes a first sensing layer, a second sensing layer and an insulative layer therebetween. Each of the first sensing layer and the second sensing layer has capacitive sensing strings and electromagnetic antenna strings. Each capacitive sensing string is composed of capacitive sensing units. The electromagnetic antenna strings are arranged. Each of the capacitive sensing strings and the electromagnetic antenna strings is connected with a tiny wire. The capacitive sensing strings on the first sensing layer are crossed with the second capacitive sensing strings on the second sensing layer to form complementary patterns. The capacitive sensing units on the first sensing layer and the second capacitive sensing units on the second sensing layer form a grid-shaped capacitive sensing unit matrix. The electromagnetic antenna strings on the first sensing layer are crossed with the electromagnetic antenna strings on the second sensing layer to form a grid-shaped electromagnetic antenna matrix.

Complex transparent touch sensor

A capacitive touch sensor includes sensing columns. Each sensing column has a common sensing electrode and driving electrodes. The driving electrodes are divided into two groups, which are connected to contacts in two bridging areas through electrode wires. Each bridging area is covered by an insulation film with through holes corresponding to the contacts. Signal wires of the driving electrodes pass through the through holes to connect the contacts of the driving electrodes of the sensing columns, which are located in a line, to form a signal channel. The signal wires connecting the common sensing electrodes pass through one of the two bridging areas and insulatively intersect the signal wires of the driving electrodes of the signal channel. Electrode extending portions of the common sensing electrodes are extended to the other bridging area to insulatively intersect signal wires of the driving electrodes of the signal channel.
