Laser separation of thin laminated glass substrates for flexible display applications
A method of separating a sheet of coated brittle material comprises the steps of providing a sheet of layered brittle material comprising a brittle layer and a coating material adhered to a surface of the brittle layer and applying a laser along a separation line in the sheet, thereby cutting the coating material and separating the brittle layer by inducing a stress fracture therein.
