摘要： A directly illuminated display unit has a display panel and one or more light sources disposed behind the display panel. A diffuser is disposed between the one or more light sources and the display panel, and a light diverting layer is disposed between the one or more light sources and the diffuser. The light diverting layer has a first light-diverting surface facing the one or more light sources and a second light diverting surface facing the display panel. The light diverting layer diverts light passing from the one or more light sources to the diffuser, thus improving the uniformity of the light in the display unit.

摘要： A directly illuminated display unit has a display panel and one or more light sources disposed behind the display panel. A diffuser is disposed between the light source unit and the display panel and a light diverting layer is disposed between the one or more light sources and the diffuser. The light diverting layer has light diverting elements on a first side of the light diverting layer facing the diffuser. Surfaces of the light diverting elements are disposed at more than one angle relative to a normal to the light diverting layer and also include one or more sharp changes of surface slope. The light diverting elements spread the illumination light so as to be more uniform. Different light diverting elements can have different apex angles. Also, different sides of a light diverting element can have best fit centers of curvature that are non-coincident.
