1. A shatter resistant, cold-formed glass article comprising:
a glass substrate comprising a first major surface; a second major surface; and a thickness measured between the first major surface and the second major surface of 0.05 mm to 2 mm;
a layer of high modulus adhesive located on the second major surface, wherein the high modulus adhesive has a modulus of elasticity of at least 500 MPa;
a surface treatment located on the first major surface; and
a frame comprising a curved surface, wherein the glass substrate is cold-formed against the curved surface and the layer of high modulus adhesive is bonded to the curved surface,
wherein the first major surface includes a curved section and the second major surface includes a curved section;
wherein the curved section of the first major surface includes a first radius of curvature greater than 30 mm and less than 1.5 m; and
wherein the first major surface is under a compressive stress, CS1, and the second major surface is under a compressive stress, CS2, wherein CS1 is different than CS2 as a result of the glass substrate being cold-formed via the layer of high modulus adhesive.
