Description

BACKGROUND Technical Field This disclosure relates generally to electronic devices, and more particularly to deformable. Background Art Portable electronic communication devices, especially smartphones, have become ubiquitous. People all over the world use such devices to stay connected. These devices have been designed in various mechanical configurations. A first configuration, known as a “candy bar,” is generally rectangular in shape, has a rigid form factor, and has a display disposed along a major face of the electronic device. By contrast, a “clamshell” device has a mechanical hinge that allows one housing to pivot relative to the other. Some consumers prefer fixed geometric configuration devices such as candy bar devices. However, many others prefer deformable electronic devices such as clamshell devices. It would be advantageous to have an improved electronic device can operate in both deformed and non-deformed states.
