Abstract:
A projection display system includes a spatial modulator that is controlled to compensate for flare in a lens of the projector. The spatial modulator increases achievable intra-frame contrast and facilitates increased peak luminance without unacceptable black levels. Some embodiments provide 3D projection systems in which the spatial modulator is combined with a polarization control panel.
