Abstract

A backlight assembly for feeding illuminating light to a passive display panel is disclosed. The backlight assembly comprises a plurality of waveguides being formed and/or embedded in at least one substrate and arranged to feed illuminating light to each sub-pixel position of the passive display panel in a manner such that each pixel region is illuminated by at least two waveguides, wherein each waveguide of the at least two waveguides is disposed to illuminate one sub-pixel position of the pixel region by a respective color channel.
