主权项

1. A printed panel allowing an image to be displayed, comprising:
at least one printed image formed by a plurality of parallel opaque bands regularly spaced from each other and separated by transparent bands; an optical system formed by a juxtaposition of rectilinear lenses, said rectilinear lenses of the optical system being arranged parallel to said plurality of opaque and transparent bands of the printed image; and at least one photovoltaic panel, a side of the photovoltaic panel which is intended to collect sunlight being arranged facing a back side of said optical system;said printed panel comprising at least one backlighting device arranged facing said back side of the optical system, said backlighting device being able to backlight the printed image, allowing the printed image to be seen in the absence of sunlight, and being able to allow, at least temporarily, at least some of the sunlight passing through said transparent bands of the printed image to be collected by the photovoltaic panel.
