Abstract
A laminator for high-precision solvent-bonding of retardation films is disclosed. The laminator is capable of producing laminates with high orientation repeatability and low in-plane stress which can otherwise create gaps between optimum theoretical performance and that which is physically realizable. Batch-mode laminators are scalable to large area mother-sheets and are suited to high-throughput manufacturing.
