Abstract
Embodiments include a light engine to generate pixels and a number of lenses positioned to receive pixels from the light engine and to project the pixels on to a field with a higher angular pixel density at an edge of the field than at a center of the field. A method according to embodiments includes generating pixels in a light engine, receiving the pixels from the light engine in a plurality of lenses, and projecting the pixels through the plurality of lenses on to a field with a higher angular pixel density at an edge of the field than at a center of the field.
