Abstract: An accessory for processor-based mobile devices is selectively securely attachable to the mobile device and at least partially wraps around at least one edge of the mobile device, so that a photo-reflective dipolar electronic display incorporated into the outer shell of the accessory can provide a visual platform for sustained image retention with negligible power consumption. Content (e.g., image data) is transmitted wirelessly from the mobile device to the accessory. Electronic and/or electrical components for receiving, directing, decrypting, and displaying images can be incorporated into a resilient sleeve, integrated into a hard shell case, or a combination of the two. Content can originate in the mobile device, or at a remote content server, to periodically update an image on the accessory.
