Abstract
The present disclosure discloses a capacitive touch panel having two surfaces, each surface at least including a region with drive lines formed therein and a region with sense lines formed therein, wherein the regions on the two surfaces correspondingly coincide in a direction perpendicular to the surfaces. The multiple drive lines extend along a first direction, while the multiple sense lines extend along a second direction perpendicular to the first direction. An end of each drive line on the periphery of the substrate is connected to a drive chip, with the other end thereof left floating; an end of each sense line on the periphery of the substrate is connected to a sense chip, with the other end thereof left floating. The present disclosure substantially shortens the length of the drive/sense lines and the resistance.
