New LCD architecture for Volumetric Displays


A design for a high-resolution solid-state volumetric display using liquid crystals in their nematic phase is explored. The display is created by stacking transparent 2D displays. Each display is illuminated from the side and operates by coupling out a totally internally reflected wave. Analysis shows that this display is possible, however highly inefficient with a coupling efficiency of 5% in some cases and suffers from slow refresh rates due to time-multiplexing of colors. The exploration shows that nematic crystals can be used for other electro-optic applications such as multi-view displays and dynamic lenses. PDF: Coupled Total Internal Reflection
