Abstract
A multi-points detecting method includes proving a touch panel including a plurality of detecting areas including a first detecting area, a second detecting area and a third detecting area. A maximum detecting value of a detecting curve is located in the first detecting area. The first detecting area and the second detecting area are analyzed to obtain a relative distance between a first touch point coordinate and a second touch point coordinate. The touch panel is defined as being touched at the first touch point coordinate or a middle point between the first touch point coordinate and the second touch point coordinate, when the relative distance is less than a predetermined distance. The touch panel is defined as being touched at the first touch point coordinate and the second touch point coordinate, when the relative distance is greater than or equal to the predetermined distance.
