A 3D display incorporates laser or saturated light sources to produce 3D images. The images may be produced on an LCD display or projector. Ambient light is filtered out through viewing glasses having passbands corresponding to the light sources. The light sources may include 2 sets of primary lights (one for each of 2 3D viewing channels) and a third set of primaries common to both channels. The display may be configured for a 2D display mode and a bandpass filter may be placed on a display surface to reduce reflections. The display may be a locally modulated or constant backlit LCD display.
