Abstract: A method for fabricating a flexible device is provided. The method includes forming a sacrificial layer on a substrate; and forming a reflective layer to reflect a laser for subsequently de-bonding the sacrificial layer from the rigid substrate back to the sacrificial layer to reduce required de-bonding energy of the laser over at least a portion of the rigid substrate. Further, the method includes forming a flexible device over the reflective layer; and separating the substrate from the sacrificial layer by irradiating the sacrificial layer using the laser.

Abstract: The present disclosure provides a method for fabricating a display substrate for a display panel. The method includes providing a flexible organic light-emitting diode (flexible OLED) substrate with a thin-film transistor (TFT) layer on the flexible OLED substrate and a patterned adhesive layer on the TFT layer, wherein the TFT layer includes at least one testing area; providing a barrier film (BF) with a patterned laser barrier layer on a surface of the BF, the surface of the BF facing the TFT layer; and bonding the BF onto the flexible OLED substrate such that at least a portion of the patterned laser barrier corresponds to the at least one testing area. The method also includes irradiating a laser beam along a cutting line on the BF to remove a first portion of the BF.
