Patent ID: 8587558

Claim:
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.
