A display includes a source that establishes an exit pupil of far field content, a reconvergent sheet disposed along an optical axis to receive light of the far field content, the reconvergent sheet being configured to reconverge the far field content in position space, a reflective surface disposed along the optical axis for reflection of light of the position space back through the reconvergent sheet after reflection off of the reflective surface to re-form the exit pupil of the far field content, and a splitter disposed along the optical axis between the source and the reconvergent sheet and configured to redirect light exhibiting the re-formed exit pupil in a direction offset from the optical axis.

A polymer compatible retroreflective bead. The bead can be used in typical retroreflective uses such as paints tapes and films in highway marking and signs having high retroreflectivity both when initially installed and over the bead lifetime, allowing vehicle drivers to see highway marking lines at night and in adverse conditions during nighttime. When installed the retroreflective beads essentially retroreflect the base color of the highway marking material in which the retroreflective beads are embedded.

The disclosed retroreflective element includes a highly durable core with an ionic copolymer and a plurality of beads. These disclosed retroreflective properties remain intact even after continued application of external forces and stresses. Further, the ionic copolymer allows for beads to be loaded into the ionic copolymer of the core, securely disposed around the perimeter of the core, or both.

A retroreflective sheeting includes: a retroreflective layer that retroreflects light incident on one surface; a light transmissive transparent colored layer provided to face the one surface of the retroreflective layer; and a light non-transmissive opaque layer provided on a side of the transparent colored layer with reference to the one surface of the retroreflective layer, in which the transparent colored layer has a region that is in contact with the opaque layer and does not overlap the opaque layer when the retroreflective layer is viewed in a plan view, and a hue of the region of the transparent colored layer is equivalent to a hue of a region of the opaque layer in contact with the region.
