Abstract
This application discloses a flexible substrate device that includes a flexible substrate and a plurality of electronic devices. The flexible substrate includes a top surface and a bottom surface opposite to the top surface, and the plurality of electronic devices formed on the top surface of the flexible substrate. The bottom surface further includes one or more strong adhesion regions and one or more normal adhesion regions that are distinct from the one or more strong adhesion regions. Each of the one or more strong adhesion regions and the one or more normal adhesion regions are configured to attach to a rigid carrier with first adhesion strength and second adhesion strength, respectively. The first adhesion strength is substantially larger than the second adhesion strength. In some embodiments, the flexible substrate device is a thin film transistor (TFT) device, and the plurality of electronic devices includes a TFT array.
