  • Publication number: 20080049330
    Abstract: A light management film package includes a first optical film having a structured surface and a second major surface, a second optical film having a first major surface and a second major surface disposed adjacent to and making contact with the structured surface of the first optical film via an adhesive layer. The structured surface of the first optical film includes a plurality of tall structures separated by short structures with the tops of neighboring tall structures separated by a distance of between about 50 and about 150 microns. The tall structures of the first optical film penetrate the adhesive layer, but the short structures do not.

  • Patent number: 7330240
    Abstract: An optical imaging system is disclosed for selective thermal transfer of a material from a donor film to a substrate. The imaging system includes a light source assembly that is configured to emit a patterned light beam. The patterned light beam includes a plurality of discrete output light segments where the segments at most partially overlap. The imaging system further includes a light relay assembly that receives and projects the plurality of discrete output light segments onto a transfer plane so as to form a projected light segment by a substantial superposition of the plurality of discrete output light segments. When a donor film that includes a transferable material is placed proximate a substrate that lies in the transfer plane, the projected light segment is capable of inducing a transfer of the transferable material onto the substrate.
