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.

Abstract: A lens system may include a lens and a leakage-reduction element overlapping the lens. The lens may include a driving electrode array, a common electrode, and a lens liquid crystal layer disposed between the driving electrode array and the common electrode. The leakage-reduction element may include a guest-host liquid crystal layer having dye molecules in a liquid crystal solution. A display device may include a display screen, which has a plurality of light emitting elements, and a lens system that receives light emitted from the display screen. Various other devices, systems, and methods are also disclosed.
