  "abstract": "An attachable article or device, such as a wristband, includes a flexible electronic display disposed thereon in a manner that is bendable or conformable to a user's wrist or other curved surface, and that enables various images to be displayed on the electronic display in a manner that is easily viewable to the user. The article further includes a connection mechanism that releasably connects the two ends of the article together. The article can, in some cases, include two different sized tail segments. As the shorter tail segment of the article tends to be subjected to more stress over time, the article can be structured in a manner that mitigates the amount of stress to which the shorter tail segment is subjected to over time, while at the same time maintaining a maximum, viewable display area on the shorter tail and longer tail segments of the article, particularly when the shorter tail segment is curved to a greater degree (e.g., when curved around a user's wrist).",

  "description_excerpt": "This patent application relates generally to dynamically flexible articles, and more particularly to an elongated, dynamically flexible article, such as a band, that includes a dynamically flexible electronic component (e.g., a dynamically flexible electronic display) and a dynamically flexible support structure coupled with the flexible electronic component, that can be mounted on and/or easily attached to other items, such as wrists, arms, mugs, shoes, belts, desktops, cabinets, phones, computers, etc.\n\nElectronic displays are commonly installed within flat, hard surfaces of electronic devices, such as computer screens, television sets, smart phones, tablet computers, etc., and in many cases are installed on accessories for the electronic devices, such as removable monitors. Many electronic devices having an electronic display are portable, and have thus become very useful in implementing mobile applications. This fact is particularly true with smart phones which have become ubiquitous, and more recently smart devices that people may wear around their wrists in a watch-like manner. However, unfortunately, typical mobile devices such as known smart phones and smart watches have electronic displays that are flat and rigid in nature. Thus, while these displays are useful in implementing many different applications, the display is typically only visible from one perspective, e.g., while the device is being handheld, or when the display of the device is positioned on the top of a person's wrist.",
