Abstract
In one embodiment, an apparatus includes one or more display layers within a display stack, the one or more display layers include a plurality of crystals configured to adjust a polarization of light passing through the one or more display layers. The apparatus includes a reference voltage layer that provides the one or more display layers with a reference voltage. The apparatus includes a plurality of pixel-drive electrodes that adjust the polarization of the light passing through the one or more display layers by adjusting an electrical potential between the plurality of pixel-drive electrodes and the reference voltage layer. The pixel-drive electrodes provide drive signals for a touch sensor and the reference voltage layer provides sense signals.
