Claim Text:
1. A method of delaminating a multilayer laminated stack of overlapping layers, the method comprising: obtaining the multilayer laminated stack including a first layer having a first surface that extends substantially over the first layer, a second layer having a second surface that extends substantially over the second layer, and a bonding layer that bonds the first layer to the second layer, wherein the multilayer laminated stack is formed by laminating the first layer to the second layer using the bonding layer, wherein the first layer comprises a touch sensor layer and the second layer comprises a display layer; applying energy to a first portion of the bonding layer such that a concentration of the energy is greater in the bonding layer than a concentration of energy in the first and second layers, the bonding layer extending substantially throughout the area of overlap of the first and second surfaces, wherein the energy weakens the bonding layer at the first portion, the first portion being disposed between respective portions of the first and second surfaces; applying a heat sink to the multilayer laminated stack to remove thermal energy from one or more of the first layer or the second layer; and breaking the weakened bonding layer at the first portion between the respective portions of the first and second surfaces.
