Abstract
A module () for a display and/or operating device (), the module () comprising a first transparent electrode () having a first matrix of a plurality of electrode islands (); a transparent piezoelectric layer () having a first and a second area; a second transparent electrode (); a transparent substrate (); and a conductive path arrangement () having at least a first conductive path () on the transparent piezoelectric layer (), wherein the transparent substrate () is coated with the second transparent electrode () and the second transparent electrode () is disposed between the transparent substrate and the transparent piezoelectric layer (), and the first area is coated with the first transparent electrode and the second area is coated with the second transparent electrode (); and the electrode islands () are arranged electrically insulated from one another on the first area of the transparent piezoelectric material (), wherein the at least first conductive path () of the conductive path arrangement () is electrically connected to at least one of the electrode islands (), and at least the first conductive path () and/or at least one of the electrode islands () has a rough surface structure with a maximum roughness depth of 4 μm.
