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 and a Tan Delta peak value of 0.5 or greater, or from 1 to 2.

A display film comprising:
- a transparent glass layer having a thickness of 250 micrometers or less;
- and
- a transparent energy dissipation layer fixed to the transparent glass layer, the transparent energy dissipation layer comprising a cross-linked polyurethane and having a glass transition temperature 27 degrees Celsius and negative 25 degrees Celsius and a Tan Delta peak value between 0.5 and 2.0,
- wherein the display film has a haze of 2.0% or less.
