An LCoS projector based on LED illuminator is proposed with simulation analysis and prototype evaluation for adding capability of high dynamic range in 2D presentation with switchability to 3D function. Evaluation shows each projection pattern can keep uniformity performance. Extinction ratio reaches 100:1 with overall efficiency up to 15%.
