Abstract

A touch module includes a substrate, a touch sensing layer, a first transparent adhesive layer, and a second transparent adhesive layer. The substrate has a visible area and a peripheral area surrounding the visible area. The touch sensing layer is disposed on the substrate and located in the visible area. The first transparent adhesive layer is disposed on the touch sensing layer, and a dielectric constant of the first transparent adhesive layer is between 1.5 and 3.0. The second transparent adhesive layer is disposed on the first transparent adhesive layer, and a dielectric constant of the second transparent adhesive layer is between 3.0 and 8.0.
