Abstract

A framework for forming an electronic display includes a primary electronic device, at least one coupling electronic device, and at least one secondary electronic device. The primary electronic device includes a system on a chip electronically coupled to a display screen of the primary electronic device. The at least one coupling electronic and the at least one secondary electronic device each includes an integrated circuit and a corresponding display screen. Each electronic device includes at least one connector configured to electronically couple to the connector of another electronic device. The system on a chip of the primary electronic device controls the display screen of each of the electronic devices to display a portion of the electronic display.
