Abstract
Systems, methods and apparatuses are described for dimming one or more portions of an extended reality (XR) display. Control circuitry may be configured to generate for display, at the display, an XR object. A dimmable optical element may comprise a plurality of up-converting nanoparticles and a photochromic material, and is configured to cause a change in color of at least a portion of the display. The dimmable optical element may be irradiated with light of a first energy level which causes the plurality of upconverting nanoparticles to emit light of a second energy level higher than the first energy level. The photochromic material may absorb the light of the second energy level to cause the change in color of the at least a portion of the display.
