## Background
FIELD
The subject matter herein generally relates to electronic displays, and more particularly to a framework for forming a composite electronic display from a plurality of electronic devices, wherein each electronic device displays a portion of the electronic display.
BACKGROUND
As electronic devices have become more common, the ability to display data and information thereon has increased. The size of a portable display is often limited as it must be held in one or two hands of a user. Additionally, smaller electronic devices are more portable than larger electronic devices.
