摘要： A touch system and an optical touch system with a power-saving mechanism are presented. The touch system includes a sensing module and a processing module electrically connected to the sensing module; the optical touch system includes an optical sensing module and a processing module electrically connected to the optical sensing module. The processing module modulates a working frequency and/or a working voltage of the processing module according to a touch point count on a touch region, a preset function of the processing module, and/or an imaging count detected by the optical sensing module, so as to decrease a power consumption of the processing module. An electronic device equipped with such system may not only dynamically adjust the working frequency and/or the working voltage of the processing module, but also can determine a working frequency and/or a working voltage satisfying a report rate through an input of the system.
