Abstract:
A system for three-dimensional viewing of a display, the display presents a frame divided into at least one first region presenting at least a part of a first image and at least one second region presenting at least a part of a second image, the system comprising a first and a second light polarizing layers each being divided into first subareas and second subareas, said second subareas being adjacent to said first subareas or being separated from said first subareas via opaque regions, said first subareas polarizing light in a first orientation, said second subareas polarizing light in a second orientation, said first layer being closest to the display, said second layer being between said first layer and a viewer, said first and second layers being in a distance from one another and said first and second subareas being distributed across and along said first and second layers such that light emanating from the at least one first region reaches one of the eyes of the viewer and is substantially blocked from the other eye, whereas light emanating from the at least one second region reaches the other eye of the viewer and is substantially blocked from the first eye, wherein at least one of said first and second light polarizing layers includes a light polarizing sublayer and a sublayer of multiple on and off switchable light rotating means, the system further comprising a multi-line controlling switching means, each of said multiple switchable light rotating means of each of said sublayers of multiple on and off switchable light rotating means being individually switched on and off by said multi-line controlling switching means, such that size of said first and second subareas is under control of said multi-line controlling switching means, such that the system is adjustable for accommodating various positions and distances of the viewer from the display.
