Abstract: Flexible display devices, such as flexible cover lens films, are discussed and provided herein. The flexible cover lens film has good strength, elasticity, optical transmission, wear resistance, and thermostability. The cover lens film includes a hard coat layer with a thickness from about 5 μm to 40 μm, an impact absorption layer with a thickness from about 20 μm to 110 μm, and a substrate layer with a thickness from about 10 μm to 175 μm and is disposed between the hard coat layer and the impact absorption layer. By combining the hard coat layer and the impact resistant layer, the cover lens film is both flexible and strong with hardness from 6H to 9H.

Abstract: Embodiments of the present disclosure generally relate to imprint lithography, and more particularly to methods and apparatus for creating a large area imprint without a seam. Methods disclosed herein generally include separating the curing time of the features in a stamp or product from the curing time of the seam and the periphery. The seam and periphery can be cured first or the seam and periphery can be cured last. Additionally, the seam curing operations can be performed on the master, on the stamp, or on the final product.
