Abstract: A 3D laser projection systems and methods are disclosed herein. A laser projection system includes a left projector head and a right projector head, wherein a first video projected onto a movie screen by the left projector head has a first polarization and a second video projected onto the movie screen by the right projector head has a second polarization different from the first polarization. The laser projection system can include a laser light generator located a first defined distance away from the left projector head and a second defined distance from the right projector head and coupled to the left projector head and the right projector head with fiber optic cables that transmit light from the laser light generator to the left projector head and the right projector head. The laser light generator includes a laser diode configured to output light and to transmit it to the fiber optic cables.

Abstract: The present invention relates to the removal of ion contaminations from liquid crystal layers in liquid crystal display devices. The ions are removed by means of so called ion pumping, which utilizes the anisotropic viscosity of liquid crystals. The ions are pumped up and down in the liquid crystal layer by means of an alternating electric filed. The alternating electric field simultaneously alters the alignment of directors in the liquid crystal. The viscosity in the liquid crystal is related to the director directions, and the ions are thereby moved in non-closed trajectories. The inventive ion pumping can be further improved using an asymmetric or biased alternating electric field.

Abstract: The present invention relates to the removal of ion (42, 44, 902) contaminations from liquid crystal layers (901) in liquid crystal display devices (900). The ions (42, 44, 902) are removed by means of so called ion pumping, which utilizes the anisotropic viscosity of liquid crystals. The ions (42, 44, 902) are pumped up and down in the liquid crystal layer by means of an alternating electric filed. The alternating electric field simultaneously alters the alignment of directors (41) in the liquid crystal. The viscosity in the liquid crystal is related to the director directions, and the ions (42, 44, 902) are thereby moved in non-closed trajectories (43, 45). The inventive ion pumping can be further improved using an asymmetric or biased alternating electric field.
