1. A 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 comprises:
an electrode portion; and
a silver trace portion electrically connected to the electrode portion; 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%.
