Integrated touch screen

摘要

In one embodiment, an apparatus includes a display stack for a touch-sensitive screen. The display stack comprises a plurality of layers in which a top layer comprises a substantially transparent cover layer. The display stack is configured to display a color image. The apparatus also includes a touch sensor provided within the display stack. The touch sensor comprises a plurality of first conductive electrodes contacting a layer of a subset of the plurality of layers of the display stack. The subset of the plurality of layers is below the substantially transparent cover layer. The touch sensor also includes a plurality of second conductive electrodes contacting a layer of the subset of the plurality of layers.
