Patent ID: 8810526

Claim:
A touch apparatus, comprising: a touch panel including an upper substrate and a lower substrate, the upper and lower substrates respectively having a plurality of electrodes disposed thereon; a plurality of voltage storage elements, each of the plurality of voltage storage elements coupled to each of the plurality of electrodes; a voltage supply unit coupled to the plurality of electrodes and adapted to respectively provide and respectively not to provide a first voltage to the plurality of electrodes, wherein when the voltage supply unit does not provide the first voltage to the plurality of electrodes and one of the plurality of electrodes on the upper substrate electrically connects to one of the plurality of electrodes on the lower substrate, the voltage storage elements corresponding to the electrically connected electrodes are adapted to achieve a voltage balance within an energy storage time and store a second voltage of the electrically connected electrodes, the energy storage times of a part of the plurality of voltage storage elements at least partially overlap with each other, and the energy storage times of two of the plurality of voltage storage elements respectively coupled to two adjacent electrodes do not overlap with each other; and a processing unit coupled to the plurality of electrodes and the voltage storage elements and adapted to adopt the second voltages stored in the voltage storage elements which correspond to the electrically connected electrodes when the voltage balance is achieved.
