Abstract
A lighting unit for a display panel includes a light distribution module, an array of out-couplers, and a beam spot array generation module. The light distribution module includes a plurality of output waveguides for configurably distributing illuminating light between the output waveguides. Each out-coupler is coupled to an output waveguide and configured to out-couple a portion of the illuminating light to propagate towards the display panel. The beam spot array generation module is configured to receive portions of the illuminating light out-coupled by out-couplers of the array of out-couplers and to convert each portion to illuminate a zone of the display panel with an illuminating light field comprising an array of light spots. Each light spot is configured for illuminating an individual pixel or sub-pixel of the zone of the display panel.
