CPC G06F 3/041 (2013.01) | 10 Claims |
1. A touch sensor having a visible area and a peripheral area adjacent to at least one side of the visible area, the touch sensor comprising:
a substrate;
a plurality of sensing channels disposed at intervals on a surface of the substrate, wherein each of the sensing channels extends from the visible area to the peripheral area to form an electron transferring path across the visible area and the peripheral area, and comprises:
an electrode portion; and
a silver trace portion electrically connected to the electrode portion;
wherein the electrode portion and the silver trace portion are on a same horizontal plane; and
a protective layer disposed on the substrate and covering and encapsulating the sensing channels;
wherein the sensing channels and the protective layer are configured to withstand a salt spray test, and, after the touch sensor is subjected to the salt spray test with sodium chloride solution of a mass percentage concentration of 5% at a rate of 1 mL/H to 2 mL/H under an ambient temperature of 35° C. for 48 hours, a resistance change rate of any one of the sensing channels is less than or equal to 10%, and a resistance distribution difference between the sensing channels is less than or equal to 10%.
