Abstract:
1. A switchable autostereoscopic display device comprising a display panel, and a lenticular element arrangement arranged over the display panel, the lenticular element arrangement comprising an array of lenticular elements which comprise electro-optic material adjacent to an optically transparent layer, and electrodes for applying electric fields to the electro-optic material, the refractive index of the electro-optic material being switchable by the selective application of an electric field to define 2D and 3D modes of operation of the display device, wherein the optically transparent layer comprises a birefringent material, and wherein the optically transparent layer has substantially the same ordinary and extra-ordinary refractive index as the electro-optic material when in the 2D mode of operation.
