Abstract

A light-emitting layer of an apparatus includes an addressable array of light-emitting elements including a first light-emitting element and a periodic optical layer overlaying the light-emitting layer. The periodic optical layer includes at least a first periodic optical feature having a first optical power and a second periodic optical feature having a different optical power. A first controllable light-steering layer is disposed between the light-emitting layer and the periodic optical layer. The first controllable light-steering layer is switchable between directing light from the first light-emitting element through the first periodic optical feature and directing light from the first light-emitting element through the second periodic optical feature.
