Abstract
A multi-touch positioning method for a capacitive touch panel includes following steps. A candidate touching position array including a first and a second candidate position groups is generated when the capacitive touch panel is touched by three objects. The first, the second and the third candidate position groups include three candidate positions, respectively. The signal magnitude sensed by a sensing element and respectively corresponding to the first, the second and the third candidate position groups are compared. One of the three first, the three second and the three third candidate positions are respectively determined as a first, a second and a third actual touching positions according to the compared result.
