Abstract
An edge-lit backlight having a light recycling cavity with concave transflector is disclosed. The edge-lit backlight has an output area and includes a back reflector facing the output area of the backlight. The backlight further includes a transflector that partially transmits and partially reflects incident light, the transflector being shaped to form a concave structure facing the back reflector to provide one or more recycling cavities therebetween, where the one or more recycling cavities substantially fill the output area of the backlight. The backlight further includes at least one light source positioned adjacent a first edge of the backlight. The at least one light source is operable to inject light into the one or more recycling cavities through an input surface of the one or more recycling cavities, where the input surface is substantially orthogonal to the output area, and where the at least one concave structure converges with the back reflector in a direction distal from the input surface.
