摘要： 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.

摘要： Direct-lit light backlights and associated methods and components are disclosed. The backlight has an output area such as a front diffuser behind which a plurality of light sources are disposed. A diverter having a first and second reflective surface is disposed between at least two light sources and the front diffuser. The first reflective surface is obliquely disposed to redirect at least some of the light emitted by the light source towards the front diffuser away from the front diffuser. The second reflective surface is obliquely disposed to redirect at least some light propagating laterally relative to the front diffuser towards the front diffuser.

摘要： Direct-lit backlights and associated methods and components are disclosed in which a transflector that partially transmits and partially reflects incident light is shaped to form at least one concave structure facing a back reflector of the backlight. This provides at least one recycling cavity therebetween, the at least one recycling cavity substantially filling the output area of the backlight. At least one light source is disposed behind the output area to inject light into each cavity, and can be positioned in the recycling cavity or behind an aperture in the back reflector. The cavities are preferably shallow and wide, having a width-to-depth ratio of at least 5 or 10, and can provide uniform brightness and color at the output area with sparsely distributed light sources and in a thin profile backlight.
