Abstract
A display device provided with a polarising photovoltaic module includes (a) a plurality of polarisers; (b) a plurality of pixels which emit or transmit light referred to as image light; (c) a plurality of photovoltaic active zones and a plurality of openings, two adjacent photovoltaic active zones forming an opening and said photovoltaic active zones being arranged between the pixels and the polarisers; wherein said polarisers are semi-reflective and are made up of one or more surfaces selected among planar surfaces, which are concave or convex, and have parabolic, conical, pyramidal, tetrahedral, semi-cylindrical or cylindrical-parabolic shapes, said polarisers being arranged so as to concentrate, by reflection, a first linear polarised component of the ambient light onto said photovoltaic active zones, as well as to transmit, through the polarising photovoltaic module, a second linear polarised component of the ambient light or of the image light.
