1. A method of forming a curved glass article comprising:
bending a glass sheet at a temperature less than the glass transition temperature of the glass sheet to conform with a curved surface of a mold comprising a self-adhesive layer disposed on the curved surface, wherein the glass sheet comprises a first major surface and a second major surface, wherein the second major surface is opposite to the first major surface, and wherein the first major surface is adhered to the self-adhesive layer, wherein the self-adhesive layer holds the glass sheet in a bent configuration;
bonding a frame to the second major surface of the glass sheet;
removing the glass sheet from the self-adhesive layer;
wherein the self-adhesive layer provides an adhesive force via surface interaction with the glass sheet, wherein the adhesive force is between about 1 kgf/cm2 and 10 kgf/cm2.
