Tandem circuit structure and touch device

The invention provides a tandem circuit structure for a touch device and the touch device. The tandem circuit structure comprises a control unit and a plurality of touch circuit (at least one of a touch sensing unit and a touch driving unit), wherein the touch circuits are tandem in sequence, and the first touch circuit is coupled with the control unit. Compared with the existing structure that a plurality of sensing units and driving units are respectively controlled by a plurality of control units, the tandem circuit structure is capable of all the touch sensing unit and touch driving units through one or less control unit, so that the cost and electricity consumption are reduced and the boundary induction problems can be avoided more effectively. 本发明提供种用于触控装置的串接式电路结构及触控装置。此串接式电路结构包括控制单元及多个触控电路(触控感应单元及触控驱动单元中至少者)。各触控电路依序串接，且第1个触控电路耦接该控制单元。相较于多个感应单元及驱动单元分别受控于多个控制单元的现有结构，本发明仅须个或更少的控制单元便能控制所有触控感应单元及触控驱动单元，从而降低成本及耗电，更能有效避免边界感应问题。
