Abstract:
An apparatus includes a light guide. A first light input section receives light in a first direction into said light guide. First direction-dependent outcoupling structures selectively couple out light propagating in said first direction in said light guide. A second light input section receives light in a second direction into said light guide. Said second direction is different than said first direction. Second direction-dependent outcoupling structures selectively couple out light propagating in said second direction in said light guide.
