MULTI-TOUCH DETECTION METHOD FOR TOUCH PANEL |
摘要 |
<p>A multi-touch detecting method for a touch panel (100) is provided. The touch panel includes two anisotropic conductive layers (113, 123) which are overlapped, wherein the first conductive layer has a plurality of first electrodes (114) disposed along a first-axis direction (x), and the second conductive layer has a plurality of second electrodes (124) disposed along a second-axis direction (y). The multi-touch detecting method includes the steps of: sensing the second electrodes to obtain a first voltage function when a first voltage (Vdd) is provided to the first electrodes; sensing the second electrodes to obtain a second voltage function when the first voltage is provided to a portion of the first electrodes and is not provided to another portion of the first electrodes; and calculating the positions of two contact points ((x 1 , y 2 ) and (x 2 , y 1 )) in the second-axis by using the first and the second voltage functions.</p> |
