NOVELTY - The panel (1) has a printed image (2) that is formed by a set of parallel opaque bands (4) that is regularly spaced from/to each other and are separated from each other by transparent bands (5). A back light unit (10) is arranged with regard to a back face of an optical system (3). The backlight unit is able to allow visualization of the printed image in the absence of sunlight and is ready to allow temporarily a partial transmission of the sunlight passing through the bands of the image, where the sunlight is collected by photovoltaic panel (8).    USE - Backlighted printed panel for presenting an advertisement or general information for an application. Uses include but are not limited to advertising panel, poster, street furniture, store sign, and road control panel.    ADVANTAGE - The backlight unit is able to allow visualization of the printed image in the absence of sunlight and is ready to allow temporarily the partial transmission of the sunlight passing through the bands of the image, where the sunlight is collected by photovoltaic panel, thus allowing visualization of the message formed by images apart from the sunning phases without degrading luminous transmission during the sunning phases. The panel ensures homogeneity of lighting on all surfaces of the backlight unit. The backlight unit is devoid of any obstacle in the incident light of the sun, thus limiting sunlight transmission losses in the panel in an optimized manner. The panel is electrically autonomous while collecting and storing light radiation of the sun, and does not require any electric connection with the network. The panel provides backlight for images in the absence of solar light radiation.
