Abstract
A touch system includes a processor and a touch array. The touch array includes touch units. Each of the touch units includes a driving electrode, a first sensing electrode, and a second sensing electrode. A first capacitor is formed between the first sensing electrode and the driving electrode. A second capacitor is formed between the second sensing electrode and the driving electrode. The processor is configured to: determine whether the touch array operates in an underwater mode according to the first original capacitance value and the second original capacitance value; determine whether a conductor touch event occurs according to a first threshold value and a voltage across the first capacitor when the touch array operates in the underwater mode; and determine whether a non-conductor touch event occurs according to a second threshold value and a voltage across the second capacitor when the touch array operates in the underwater mode.
