1. A first method, comprising:
- providing a substrate having a first surface;
disposing the substrate on a carrier;
disposing an adhesive layer between at least a portion of the substrate and at least a portion of the carrier, and baking the carrier and the adhesive at a temperature that is less than a glass transition temperature of the adhesive layer;
disposing at least one organic light emitting device (OLED) over the first surface of the substrate;
after disposing the at least one OLED, disposing a barrier layer over the OLED; and
removing the adhesive layer from the substrate, wherein the adhesive layer has an adhesive fracture energy of less than 200 J/m2 when it is removed from the substrate.

Abstract
A first device and methods for manufacturing the first device are provided. The first device may comprise a flexible substrate and at least one organic light emitting device (OLED) disposed over the flexible substrate. The first device may have a flexural rigidity between 10−1 Nm and 10−6 Nm, and the ratio of the critical strain energy release rate to the material density factor for the first device may be greater than 0.05 J m/Kg.

19. A first method, comprising:
-
(i) providing a substrate having a first surface; (ii) disposing the substrate on a carrier, disposing an adhesive layer between at least a portion of the substrate and at least a portion of the carrier, baking the carrier and the adhesive at a temperature that is less than a glass transition temperature of the adhesive layer, and disposing at least one organic light emitting device (OLED) over the first surface of the substrate; (iii) disposing a barrier layer over the OLED; and (iv) removing the adhesive layer from the substrate, wherein the adhesive layer has an adhesive fracture energy of less than 200 J/m2 when it is removed from the substrate.
