Abstract

Display devices with high dynamic ranges approaching the limitations of the human eye are discussed herein. High dynamic range projections systems may be 2D or 3D and devices may or may not be implemented with polarization preserving optics for high efficiency. In one embodiment, 2D HDR projection systems may compensate the modulator for varying transmission and contrast versus field of view. In another embodiment, 3D HDR projection systems may include a global or pixelated/segmented modulator. The global or pixelated/segmented modulator may be included in a stereoscopic polarization switch or in a polarization-preserving stereoscopic projection system. Additionally, a combination of global/global or pixelated/pixelated, or global/pixelated modulators may be used.
