<p><P>PROBLEM TO BE SOLVED: To provide a touch circuit of a capacitive touch sensor and a scanning method. <P>SOLUTION: In the touch circuit of the capacitive touch sensor and the scanning method, a plurality of traces of the capacitive touch sensor are scanned by group direction, the overall scanning time is shortened, and noise effects are reduced. After all the traces are scanned, secondary scan is executed to the trace which an object is in contact with further and the object is further accurately positioned. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
