<p>The invention relates to a stereoscopic three-dimensional display device (1), in particular a digital screen, comprising: (a) an array (3) of pixels (4a, 4b) distributed between a first group forming a first image and a second group forming a second image; and (b) an array (5) of surface elements (6,16, 26) that absorb visible light at least partially, said array (5) being parallel to the screen (1) and placed between the array (3) of pixels (4a, 4b) and the observer (8). The device is characterised in that the surface elements (6, 16, 26) comprise photovoltaic cells (7) on at least one of the faces thereof. The device is also characterised in that the surface elements are configured in relief such as to limit the output angle (a) of the first and second image and are disposed such that, for a given observation distance, the right eye (9) of a user (8) of the display device (1) only sees the first image and the user's left eye (10) only sees the second image. In this way, a 3D digital display screen is formed that can generate an electrical current from photovoltaic cells in relief disposed in front of the array (3) of pixels (4a, 4b).</p> |
