Zusammenfassung:A cover window for a display includes a multilayer polymer film. The multilayer polymer film includes a first transparent, colorless polymer layer having a first elastic modulus and a second transparent, colorless polymer layer having a second elastic modulus. Each of the first and second transparent, colorless polymer layers include a polyimide, a polyamide imide, or a block copolymer of a polyimide. The polymers of both the first and second transparent, colorless polymer layers are cross-linked. The first elastic modulus is different from the second elastic modulus. The first and second transparent, colorless polymer layers are bonded by consolidation and cross-linking. The first transparent, colorless layer of the multilayer polymer film is the layer farthest from the display.
