Abstract
A device comprises a display that includes an aperture layer, a plurality of light sources, and a piezo material. The aperture layer includes a plurality of apertures. The plurality of light sources is arranged to correspond to the plurality of the aperture. The piezo material is coupled to the light sources and is configured to alter a distance between the light sources and the corresponding apertures.
