Abstract:
Reflective stacks including heat spreading layers (320) are described. In particular, reflective stacks including polymeric multilayer reflectors (330). Heat spreading layers (320) may include natural or synthetic graphite or copper.

Abstract:
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 moire fringes occur when the flexible unitary lightguide is used as a backlight in a pixelated display.

Abstract:
The present disclosure relates to reflective trays (101) comprising a polymeric dielectric multilayer reflector material, backlight modules incorporating said reflective trays, articles using said backlight modules, and methods of making said reflective trays useful for backlight modules. In particular, the backlight modules have a reduced tendency to leak light into unwanted areas, and also form a compact unit having a narrow bezel, that at least partially surrounds the components of the backlight and/or the display.
