The invention relates to a multi-lens lenticular system and a lighting device for an autostereoscopic display. Said display comprises, in the direction of light, an illuminating matrix (7), a focusing matrix (8), and a transmissive data panel (5). The illuminating matrix is provided with a plurality of light-penetrated controllable openings (21). The focusing matrix (8) focuses the light of said openings (21) in such a way that the data panel (5) and a preferred visible zone (6) are illuminated in a directed manner while being composed of a multi-lens lenticular system (LM) whose lenticles (L) are structured into several subordinate lenticles (S1, S2, . . . ). The subordinate lenticles are arranged such that a multiple number of images having an associated enlarged brightness distribution (V) ranging from (A) to (C′) is created in the visible zone (6) by the light of an opening (21) while the resulting images of laterally adjoining openings (21) overlap in the edge regions thereof, thus creating a nearly homogeneous brightness distribution (V). The homogeneous brightness visibly increases the quality of the image for the viewer.
Multi-lens lenticular array, particularly for autostereoscopic displays, with a plurality of lenticles (L) bordering each other and arranged in parallel, whereby to said lenticles (L) a central axis (m) which divides the aperture of the lenticle (L) is assigned, characterized in that each lenticle (L) is structured as several connected sublenticles (S1, S2, . . . ), whereby all sublenticles (S1, S2, . . . ) together cover the aperture of the lenticle (L), and one or several sublenticles (S1, S2, . . . ) are arranged offset in the axial direction of the central axis (m) of the lenticle (L) and/or in a lateral direction of the central axis (m) of the lenticle (L).
