Abstract
A multi-view display is switchable between single view and multi-view modes, and uses lenticular arrangement over a display panel which includes birefringent electro-optic material adjacent to a non-switchable optically transparent layer. The non-switchable optically transparent layer has a refractive index substantially equal to the extra ordinary refractive index of the birefringent electro-optic material. In the single view mode, the birefringent electro-optic material defines a non-switched state, and the polarization of the light from the display panel and incident on the lenticular arrangement is linear and aligned with the optical axis of the birefringent electro-optic material at the surface where the display output light is received. In the multi-view mode, the birefringent electro-optic material defines a switched state in which the optical axis is aligned perpendicularly to the display output surface.
