    • The present invention relates to a method for detecting touch points and a touch panel using the same. The method includes the steps of: providing a resistive pressure-sensing matrix includes M X-axis sensing lines and N Y-axis sensing lines, wherein the ith X-axis sensing line and the jth Y-axis sensing line are short-circuited when a preset range covering an overlapped region between the ith X-axis sensing line and the jth Y-axis sensing line is pressed; applying a scanning voltage to the pth Y-axis sensing line in a pth scanning period; detecting the M X-axis sensing lines to judge whether the scanning voltage is detected; and determining a touch coordinate as (q, p) when the qth X-axis sensing line receives the scanning voltage in the pth scanning period, wherein M, N, i, p and q are positive integers, 0
