摘要： A display film comprises a transparent glass layer including two or more co-planar glass layer segments and a thickness defined by a first major surface and a second major surface opposing the first major surface being less than 500 micrometers; interstitial polymer material separating adjacent segments; and transparent energy dissipation layer having a glass transition temperature of 27 degrees Celsius or less and a Tan Delta peak value of 0.5 or greater and being disposed on the first major surface.
