An apparatus includes a liquid crystal layer comprising a first region and a second region. The first region comprises a first plurality of liquid crystal molecules in a first state and the second region comprises a second plurality of liquid crystal molecules in a second state different from the first state. The apparatus also includes a camera positioned to receive light propagating through the second region, a first driver circuit configured to apply a first set of voltages to a first set of electrodes in the first region, and a second driver circuit configured to apply a second set of voltages to a second set of electrodes in the second region.
