Abstract
A backplate of a display device has a first rigid region, a second rigid region spaced apart from the first rigid region, and a flexible region between the first rigid region and the second rigid region. The flexible region includes an electromagnet and encloses a magneto-rheological fluid that suspends magnetic particles. The rigidity of the flexible region changes responsive to changes in magnetic field generated by the electromagnet.
