Abstract
A method for determining touch point coordinates on capacitive type touch panel includes following steps. A touch panel having a conductive layer, a plurality of first electrodes, and a plurality of second electrodes is provided. A first signal curve Ais obtained by driving and sensing each first electrode. A second signal curve Ais obtained by driving and sensing each second electrode. A third signal curve Bis obtained by driving and sensing each first electrode, wherein the second electrode opposite to the sensed first electrode is grounded. A fourth signal curve Bis gotten by driving and sensing each second electrodes, wherein the first electrode opposite to the sensed second electrode is grounded. The coordinates of the touch points are obtained by comparing the first signal curve A, the second signal curve A, the third signal curve B, and the fourth signal curve B.
