Abstract
The present invention relates to three-dimensional (3D) imaging, and more particularly, to a multi-planar 3D display system using a plurality of liquid crystal shutters which incorporate nematic liquid crystals having polymer-stabilized liquid cholesteric textures. The polymer stabilized mixture includes a combination of liquid crystals, a chiral additive, monomer and a photo initiator. By using nematic liquid crystals having polymer-stabilized cholesteric textures in a multi-planar 3D display system, a substantially haze-free 3D image can be viewed on the multi-surface optical device from a wide range of viewing angles.
