Abstract
A display device, in particular digital display screen, with integrated photovoltaic cells, including (a) an array of image zones emitting light or backlit by a light source placed behind the array of image zones, (b) an array formed by a plurality of photovoltaic cells and a plurality of orifices, in which array two neighboring photovoltaic cells form an orifice, and (c) a lenticular array making it possible to focus the light emitted by the image zones into the orifice between two neighboring photovoltaic cells. The lenticular array of the display device is positioned between the array of image zones and the array of photovoltaic cells.
