Invited Paper: Roll-to-Roll Manufacturing Considerations for Flexible, Cholesteric Liquid Crystal (ChLC) Display Media

摘要

Roll-to-roll methods and equipment to manufacture a bistable, passively driven display media on a flexible substrate have been developed. Using continuous coating techniques and equipment, cholesteric liquid crystal droplets in a gelatin binder and a dark layer are simultaneously coated onto laser-etched patterned, transparent ITO conductors on a polymeric web. Second conductors are printed with a UV-curable polymer thick film ink over the active display layers, followed by slitting and chopping to complete the manufacture of display media in a full roll-to-roll mode. Segmented and matrix display media can be generated using these techniques. This paper will focus on the manufacturing considerations for producing matrix display media.
