Abstract: An apparatus and a method of manufacturing the apparatus is provided. The apparatus comprises: a first electromagnetic shielding layer; a second electromagnetic shielding layer; at least one sensing layer, positioned between the first electromagnetic shielding layer and the second electromagnetic shielding layer, comprising an array of touch sensors and multiple traces for connecting the touch sensors to touch sensing circuitry; and at least one electromagnetic shielding wall, extending from the first electromagnetic shielding layer to the second electromagnetic shielding layer, for shielding one or more of the multiple traces from conductive user input objects.
