Abstract
A touch panel for determining real coordinates of multiple touch points is provided. The touch panel for determining real coordinates of multiple touch points comprises a sensing path layer having a plurality of first paths and a plurality of second paths for detecting the raw coordinates of said multiple touch points, and an Eliminating Path Layer having a plurality of third paths for eliminating ghost coordinates of said multiple touch points from said raw coordinates to output said real coordinates of said multiple touch points. The method of determining real coordinates of multiple touch points on the touch panel is also provided.
