Abstract
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 iX-axis sensing line and the jY-axis sensing line are short-circuited when a preset range covering an overlapped region between the iX-axis sensing line and the jY-axis sensing line is pressed; applying a scanning voltage to the pY-axis sensing line in a pscanning 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 qX-axis sensing line receives the scanning voltage in the pscanning period, wherein M, N, i, p and q are positive integers, 0<i, q<=M and 0<p<=N.
