Abstract
A capacitive touch sensor includes multiple first-axis traces, multiple second-axis traces, an insulation layer and multiple metal traces. Each first-axis trace includes multiple first touch-sensing pads and first connecting lines connected therebetween. Each second-axis trace includes multiple second touch-sensing pads and second connecting lines connected therebetween. At least one of the first connecting line and the second connecting line is a metal printing line.
Claims20
A capacitive touch sensor, comprising:
- a plurality of first-axis traces, wherein each of the first-axis traces comprises a plurality of first touch-sensing pads and first connecting lines, the first touch-sensing pads are arranged along a first direction, each of the first connecting lines connects two adjacent first touch-sensing pads, and each of the first connecting lines has an enlarged portion at each of the opposed end portions;
- a plurality of second-axis traces intersected with the first-axis traces, wherein each of the second-axis traces comprises a plurality of second touch-sensing pads and second connecting lines, the second touch-sensing pads are arranged along a second direction different to the first direction, each of the second connecting lines connects two adjacent second touch-sensing pads, and each of the second connecting lines has an enlarged portion at each of the opposed end portions;
- an insulation layer at least formed between the first connecting lines and the second connecting lines;
- and
- a plurality of metal traces disposed on the periphery of the capacitive touch sensor, electrically connected to the first-axis traces and the second-axis traces, and connected to at least one signal output terminal for transmitting a sensing signal of the capacitive touch sensor to a back-end signal processing unit through the signal output terminal.
