Patent ID: 8711292

Claim:
An apparatus comprising: a display stack for a touch-sensitive screen, the display stack comprising a plurality of layers in which a top layer comprises a substantially transparent cover layer, the plurality of layers further comprising a first polarizer that is below the substantially transparent cover layer and a second polarizer that is below the substantially transparent cover layer and a liquid crystal layer, the display stack being configured to display a color image; and a touch sensor within the display stack, the touch sensor comprising: a plurality of first conductive electrodes contacting a layer of a subset of the plurality of layers, the subset being below the substantially transparent cover layer; and a plurality of second conductive electrodes contacting the layer of the subset of the plurality of layers; wherein the plurality of first conductive electrodes and the plurality of second conductive electrodes are located between the first polarizer and the second polarizer; wherein the display stack is devoid of a polarizing layer between the first and second polarizers; wherein the plurality of first conductive electrodes and the plurality of second conductive electrodes are also in contact with the first polarizer; and wherein: the plurality of first conductive electrodes comprise a plurality of drive electrodes; the plurality of second conductive electrodes comprise a plurality of sense electrodes; and the plurality of drive electrodes and the plurality of sense electrodes are also in contact with a same side of the first polarizer.
