Claim:
1. A positioning method of touch points, the method is for positioning two touch points of self-capacitive touch sensing devices, the touch sensing device comprises N rows of row sensors and M columns of column sensors intersecting with the N rows of row sensors, comprising: applying first driving signals to the N rows of row sensors in sequence by a row control module to determine the row sensors (Y applying second driving signals to the M columns of column sensors by a column control module to determine the column sensor (X applying third driving signals to one end of the row sensors (Y applying the third driving signals to one end of the column sensor (X wherein M and N are integers larger than one, and m and m+I ε[1,M], and n and n+iε[1,N]; and applying the third driving signals to the row sensor (Y detecting the third driving signals in the row sensor (Y if the delay time period of the third driving signals within the row sensor (Y if the delay time period of the third driving signals within the row sensor (Y
