More Information
Summary:The present invention provides a projection display system which comprises a spatial modulator which is controlled to compensate for flare in a lens of a projector. The spatial modulator increases achievable intra-frame contrast and facilitates increased peak luminance without unacceptable black levels. Some embodiments of the present invention provide a three-dimensional projection systems in which the spatial modulator is combined with a polarization control panel. 투사형 디스플레이 시스템은 프로젝터의 렌즈에서의 플레어를 보상하도록 제어되는 공간 변조기를 포함한다. 공간 변조기는 달성가능한 인트라-프레임 콘트라스트를 증가시키고 수용불가능한 블랙 레벨들 없이 증가된 피크 휘도를 용이하게 한다. 몇몇 실시예는 공간 변조기가 편광 제어 패널과 결합되는 3D 투사형 시스템을 제공한다.
