摘要： Flexible unitary lightguide and a method of making the same are disclosed. The lightguide includes a structured input side that includes a first pattern having smaller features superimposed on a second pattern having larger features. The lightguide further includes a structured top surface that includes a first region and a different second region. The first region includes a plurality of discrete light extractors for extracting light that propagates within the flexible unitary lightguide by total internal reflection. The second region includes a taper portion for directing light from the structured input side to the first region. The light extractors form a periodic array that has a first period along the length of the flexible unitary lightguide. The first period is such that substantially no visible moir fringes occur when the flexible unitary lightguide is used as a backlight in a pixelated display.

摘要： A backlight system includes an extended area light guide (120) and crossed first (128) and second (130) prismatic recycling films. The light guide provides a first light distribution that has a maximum luminance at a first polar angle, e.g., from 70 to 90 degrees, relative to the optical axis (116) of the system. The recycling films provide a second light distribution. No diffuser film is provided between the light guide and the recycling film disposed nearest the light guide. Instead, light is specularly transmitted from the output surf ace (120a) of the light guide to the input surf ace (128a) of the recycling film nearest the light guide. The recycling films comprise prisms having refractive indices tailored to provide the second light distribution with a maximum luminance at a polar angle of 10 degrees or less. The prisms preferably have a refractive index from 1.63 to 1.76. Related methods and articles are also disclosed.

摘要： A backlight subsystem includes first and second lightguides separated by an interfacial layer. The first lightguide has an output surface oriented toward an associated first illumination field, a back surface, and at least one light input edge. The second lightguide has output surface oriented toward an associated second illumination field, a back surface, and at least one light input edge. An interfacial layer is arranged between the back surfaces of the first lightguide and the second lightguide. The interfacial layer is substantially optically non-absorbing and may be predominately optically transmissive or predominately optically reflective.
