Zusammenfassung:Articles including a substrate, a cover glass layer disposed over a top surface of the substrate, and an adhesive layer having a dynamic elastic modulus disposed between a bottom surface of the cover glass layer and the top surface of the substrate. The cover glass layer may have a thickness in the range of 1 micron to 200 microns. The dynamic elastic modulus of the adhesive layer may include a first elastic modulus in the range of 10 kPa to 1000 kPa measured at a stress frequency in the range of 0 Hertz to 5 Hertz and a temperature of 23 degrees C., and a second elastic modulus of 500 MPa or more measured at a stress frequency in the range of 10 Hertz to 1000 Hertz and a temperature of 23 degrees C. The adhesive layer may be optically transparent. The articles may be bendable electronic display devices or bendable electronic display device modules.
