Abstract
A surface capacitive touch panel, a driving method thereof, a display apparatus using the same, and an electronic apparatus using the same are provided. The surface capacitive touch panel includes a substrate, a conductive film, and a plurality of driving sensing electrodes. The conductive film is formed on the substrate. The conductive film has an anisotropy of impedance to define a lower impedance direction and a higher impedance direction. The driving sensing electrodes are disposed on at least one side of the conductive film and the at least one side is substantially perpendicular to the lower impedance direction. The surface capacitive touch panel of the invention has high positioning accuracy. The touch sensing accuracy of the display apparatus and the electronic apparatus using the surface capacitive touch panel is also desirable.
