Multiview autostereoscopic display
First Claim
1. A multiview autostereoscopic display comprising:
- a backlight unit;
a first polarized panel which transmits light emitted from the backlight unit having a first polarization direction;
a first polarization switch which changes the polarization direction of light incident thereon;
a first anisotropic device array comprising first, second, third, and fourth anisotropic devices which are sequentially and repeatedly arranged in a horizontal direction, which transmits light such that light transmitted by an anisotropic device has a polarization perpendicular to a polarization of light transmitted by a neighboring anisotropic device;
a lenticular lens array comprising a plurality of lenticular lens devices which are arranged in the horizontal direction, the lenticular lens array separating light transmitted from the first, second, third, and fourth anisotropic devices into different directions;
a second polarized panel which transmits light emitted from the first anisotropic device array having a second polarization direction;
a second anisotropic device array, comprising fifth and sixth anisotropic devices alternately arranged in the horizontal direction, which transmits light such that light transmitted by the fifth anisotropic devices has a polarization perpendicular a polarization of light transmitted by the sixth anisotropic devices;
a lenticular lens array comprising a plurality of lenticular lens devices which are arranged in the horizontal direction, the lenticular lens array separating light transmitted from the first, second, third, and fourth anisotropic devices into different directions;
a second polarized switch which changes the polarization direction of light incident thereon;
a third anisotropic device array, comprising seventh and eighth anisotropic devices which are alternately arranged in a vertical direction, which transmits light such that light transmitted by the seventh anisotropic devices has a polarization perpendicular to a polarization of light transmitted by the eighth anisotropic devices; and
a display panel which forms an image by modulating incident light.

Abstract
A multiview autostereoscopic display includes: a backlight; a first polarized panel transmitting light having a first polarization; a first polarization switch changing the polarization of incident light; a first anisotropic device array including anisotropic devices sequentially and repeatedly arranged in a horizontal direction, such that light transmitted from neighboring anisotropic devices has perpendicular polarizations; a lenticular lens array having lenticular lens devices, arranged horizontally, which separate incident light into different directions; a second polarized panel transmitting light having a second polarization; a second anisotropic device array having anisotropic devices alternately horizontally arranged, such that the anisotropic devices transmit light having perpendicular polarizations; a second polarized switch changing the polarization of light from the lenticular lens array; a third anisotropic device array having anisotropic devices, alternately vertically arranged, such that the anisotropic devices transmit light having perpendicular polarizations; and a display panel forming an image by modulating incident light.
