There is increased interest in the visualization community to experiment the benefit of HDR presentation. Current developments in HDR displays are geared towards projecting more realistic images than conventional (non-HDR) displays. The dynamic range of the natural world is approximately 14 orders of magnitude while conventional displays are limited to at most 3 orders of magnitude in luminance. A high dynamic range based on Dual Layer liquid crystal display (LCD) is built by stacking two panels one on top of the other. In this way, the dynamic range is theoretically squared and the bit depth is also increased. However, in order to minimize the parallax and reconstruction errors, dedicated splitting algorithms are needed to generate the two images which drive the panels. Moreover, to cope with the reduce transmittance of this Dual Layer LCD concept, a high brightness backlight is required and new LED technology enable a reliable implementation.
