1. A display, comprising:
an array of light-emitting diodes configured to emit light;
a collimator that is configured to collimate the light;
a masking layer that includes a plurality of holes, wherein the masking layer has first and second opposing sides and wherein the masking layer is configured to block a majority of ambient light from passing from the second side to the first side;
a microlens array layer that is configured to focus a majority of the light from the collimator through the plurality of holes from the first side to the second side;
a spacer layer having different portions with different thicknesses, wherein the spacer layer is interposed between the masking layer and the microlens array layer, and
a transparent cover layer having a non-planar exterior surface, wherein the masking layer is interposed between the spacer layer and the transparent cover layer.
