Abstract
An apparatus including a sensing arrangement including a plurality of distinct capacitive sensor electrodes distributed over a sensing area; conductive traces connected to the plurality of distinct capacitive sensor electrodes; a first shield electrode overlying at least the conductive traces; a second shield electrode underlying the conductive traces and the capacitive sensor electrodes; a display arrangement including a transparent cover; a polarizer, underlying the transparent cover; an intermediary layer, underlying the polarizer; an optical control layer, underlying the intermediary layer; wherein the sensing arrangement and the display arrangement are integrated, the first shield electrode being positioned beneath the transparent cover and above the polarizer; the capacitive sensor electrodes being positioned beneath the transparent cover and beneath the first shield electrode and above the optical control layer; and the second shield electrode being positioned beneath the transparent cover and beneath the capacitive sensor electrodes and above the optical control layer.
