Claim 0:
1. A display device suitable for head-mounting, comprising
a light source configured to emit light beams for forming an image;
an optical system configured to guide the light beams to a beam forming element, wherein the beam forming element is configured to converge each set of multiple sets of the light beams into a different point of convergence;
an optical displacer arranged between the light source and the optical system and configured to produce multiple sets of the light beams by spatially separating the light beams received from the light source into two differently polarized sets of light beams;
a polarization modulator arranged between the light source and the optical displacer and configured to polarize, when activated, the light beams provided to the optical displacer, wherein the display device is configured to activate the polarization modulator based on a brightness of the light beams when the brightness of the light beams is above a determined threshold value.
