Abstract
A method for locating a touched position on a touch panel acquires a sensing signal from a sensing area on the touch panel when the touch panel is touched. A determination is made as to whether the sensing signal of the sensing area on the touch panel is a touch signal and if so, sorting all the touch signals to obtain a decreasing sequence of strength of touch signals. Selection of groups of all the touch signals in the decreasing sequence is carried out according to a direction of decrease of strength, to divide all the touch areas into at least one group. Calculating a physical center of each of the at least one group, wherein the touch position of each of the groups is taken as the physical center and point of origin of the coordinates.
