Efficient, high brightness, high dynamic range projection

Projection is a popular form of imaging but suffers from dim peak light levels and poor contrast, limiting effective use to dark and controlled viewing environments like the cinema (Figure 1). We introduce a novel High Dynamic Range (HDR) projection technique that achieves both dark black levels and very bright peak luminance in an energy and cost efficient implementation.
