Abstract
A dynamically flexible article or device, such as an armband, includes a flexible electronic component, such as a flexible electronic display, and a flexible support structure coupled to the flexible electronic component, wherein the flexible support and the flexible electronic component are flexible along two dimensions to thereby be able to conform to a complex curved surface. The flexible support includes bending limiting structure that constrains bending of the flexible electronic component to prevent undesirable bending.
