Autostereoscopic display device using controllable liquid crystal lens array for 3D/2D mode switching

摘要

An autostereoscopic display device has an array (9) of lenticular elements (11) overlying a display panel (3), the lenticular elements comprising electro-optic material (23) and being switchable to enable 2D and 3D viewing modes. The electro-optic material, for example liquid crystal material, is contained adjacent an optically transparent layer in the form of a lenticular body (21). A birefringent material is utilized for the lenticular body, preferably with the ordinary and extra-ordinary index of refraction substantially matching that of the electro-optic material.
