Abstract
A touch apparatus includes a touch panel, voltage storage elements, a voltage supply unit, and a processing unit. The touch panel has electrodes respectively coupled to the voltage storage elements. When the voltage supply unit does not provide the voltage to the voltage storage element, the voltage storage element achieves a voltage balance within an energy storage time and stores a voltage of the corresponding electrode. The energy storage times of a part of the voltage storage elements at least partially overlap. The energy storage times of two the voltage storage elements respectively coupled to two adjacent electrodes do not overlap with each other. The processing unit is coupled to the electrodes and the voltage storage elements and adopts voltages stored in the voltage storage elements when the voltage balance is achieved.
