Light field display using birefringement materials and metamaterials

A system comprising:

• tracking means;
• a display unit comprising a first display region and a second display region;
• an optical element arranged on an optical path of the display unit, the optical element being made of any one of:
• (i) a birefringent material, (ii) a metamaterial;
• and
• at least one processor configured to:
• utilise the tracking means to determine a relative location of a first eye and of a second eye of at least one user with respect to the optical element;
• obtain a first virtual image and a second virtual image to be presented to the first eye and the second eye of the at least one user, respectively, based on the relative location of the first eye and of the second eye of the at least one user with respect to the optical element;
• generate at least one image to be employed at the display unit, based on the first virtual image, the second virtual image, the relative location of the first eye and of the second eye of the at least one user with respect to the optical element, and a relative location of the optical element with respect to the first display region and the second display region;
• and
• display the at least one image via the display unit,
• wherein the optical element is employed to re-direct light emanating from photo-emitting cells on the second display region to bend towards the first eye and the second eye of the at least one user, while allowing light emanating from photo-emitting cells on the first display region to be incident upon the first eye and the second eye of the at least one user without bending.
