1. An article comprising:
a substrate;
a cover glass layer disposed over a top surface of the substrate, the cover glass layer comprising a thickness in a range of 1 micron to 200 microns; and
an adhesive layer disposed between a bottom surface of the cover glass layer and the top surface of the substrate, the adhesive layer comprising a dynamic elastic modulus comprising:
a first elastic modulus in a range of 10 kPa to 1000 kPa measured at a stress frequency in a 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 a range of 10 Hertz to 1000 Hertz and a temperature of 23 degrees C.
