Abstract

A touch panel is disclosed. The touch panel comprises a first electrode plate and a second electrode plate spaced from first electrode plate. The first electrode plate comprises a first conductive layer and a second conductive layer opposite to the first conductive layer. The first conductive layer and the second conductive layer form a two-dimensional coordinate touching module. The second electrode plate comprises a third conductive layer. A distance between the second conductive layer and the third conductive layer is deformable. The second conductive layer and the third conductive layer form a third-dimensional coordinate touching module.
