Touch sensing system, electronic touch apparatus, and touch sensing method

摘要

A touch sensing system including a touch interface, at least one sensing unit, and a switching unit is provided. The sensing unit is coupled to the touch interface. The touch sensing system is switched to a first sensing mode or a second sensing mode by the switching unit according to a control signal. When the touch sensing system is in the first sensing mode, the sensing unit senses a first sensing signal and a second sensing signal of the touch interface. On the other hand, when the touch sensing system is in the second sensing mode, the sensing unit senses the first sensing signal according to a driving signal. An electronic touch apparatus and a touch sensing method are also provided.
