Light recycling directional control element and light emitting device using the same
摘要:
In one embodiment of this invention, an optical element comprises a light recycling directional control element and provides increased spatial color or luminance uniformity, desired angular color uniformity, and customizable light re-direction properties. In one embodiment, the optical element comprises at least one light blocking region and a lenticular lens element. Further embodiments incorporate an anisotropic light backscattering region within a light transmitting layer. The optical element may further comprise a light collimating element or an additional light lenticular lens element and light transmitting region that may be oriented parallel or perpendicular to the first lenticular lens element. Light emitting devices and displays incorporating the light recycling direction control element are further embodiments of this invention.
