Optical construction and display system

An optical construction comprising:

• a reflective polarizer comprising:
• a plurality of polymeric layers numbering at least 50 in total and co-extruded with a first outer layer, the first outer layer comprising a plurality of first particles having an average size of from about 7 to about 9 microns and partially protruding from a first major surface thereof to form a first structured major surface;
• and
• a first optically diffusive layer conformably disposed on the first structured major surface so that opposing first and second major surfaces of the first optically diffusive layer substantially conform to the first structured major surface, the first optically diffusive layer comprising a plurality of nanoparticles dispersed therein, the nanoparticles defining a plurality of voids therebetween;
• and
• an optically diffusive film disposed on the reflective polarizer and comprising:
• an optical substrate layer;
• a second optically diffusive layer disposed on the optical substrate layer and facing the reflective polarizer and comprising a plurality of nanoparticles dispersed therein, wherein for a substantially normally incident light and a visible wavelength range from about 450 nm to about 650 nm and an infrared wavelength range from about 930 nm to about 970 nm, the second optically diffusive layer has an average specular transmittance Vs in the visible wavelength range and an average specular transmittance Is in the infrared wavelength range, Is/Vs≥2.5;
• and
• a structured optical layer disposed on the optical substrate layer and facing away from the reflective polarizer and comprising a structured major surface facing away from the optical substrate layer and comprising a plurality of spaced apart elongated structures elongated along a same first direction and arranged at a substantially uniform density across the structured major surface of the structured optical layer.
