Abstract: Described examples include a display having a first light source configured to provide a first light and a second light source configured to provide a second light. The display also having a spatial light modulator configured to produce a first modulated light by modulating the first light and configured to produce a second modulated light by modulating the second light. The display also having a first diffractive optical element configured to receive the first modulated light and configured to provide a first image having a first characteristic to display optics; and a second diffractive optical element configured to receive the second modulated light and configured to provide a second image having a second characteristic to the display optics.

Abstract: An example projector includes: a first light source to provide first light; and a second light source to provide second light. A spatial light modulator produces: first modulated light by modulating the first light; and second modulated light by modulating the second light. An image direction device directs: the first modulated light to project a first image having a first pixel position; and the second modulated light to project a second image having a second pixel position.

Abstract: Apparatus for generating blue color illumination for use in a projection system a color wheel with segments of respective different color light emitting phosphors formed over light non-transmitting portions and at least one blue color generating segment. The blue color generating segment has cyan color light emitting phosphor formed over a light non-transmitting first portion and a second portion that transmits blue laser light through the wheel. A dichroic filter directs blue laser light from a light source onto the respective segments as the color wheel rotates. The light strikes the first and second portions of the blue color generating segment to generate blue light at a color point determined by both blue laser light and phosphor emitted cyan light.
