ABSTRACT:
A non-light-emitting (passive) display such as a dichroic LCD is frontally illuminated with polarized light incident obliquely upon the display, the incident light having followed multiple paths to arrive at the display from multiple directions. Relative to a typical display viewing axis, some light arrives from one side of such axis and some light arrives from the other side of such axis. An appropriately positioned light emitter, preferably comprising a reflective cavity, lamp, and polarizer, casts some light directly on the display, and casts other light, which is also substantially collimated, on an appropriately positioned reflector which re-directs incident light to the display.
