Abstract
A display film includes a transparent glass layer having a thickness of 250 micrometers or less, or in a range from 25 to 100 micrometers. A transparent energy dissipation layer is fixed to the transparent glass layer. The transparent energy dissipation layer has a glass transition temperature of 27 degrees Celsius or less, a Tan Delta peak value of 0.5 or greater, or from 1 to 2 and a Young's Modulus (E') greater than 0.9 MPa over a temperature range of −40 degrees Celsius to 70 degrees Celsius. In a preferred embodiment, the transparent energy dissipation layer comprises a cross-linked polyurethane layer or a cross-linked polyurethane acrylate layer.
