Multi-lens lenticular and illumination device for autostereoscopic display

摘要

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 (S 1, S 2, . . . ). 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.
