A gyricon display containing modified particles is disclosed. The stator is composed of at least three structural elements to be installed around the rotor provided with at least one flow regulator. Each expansion slot has an opening for mounting an information-accessing device. Each buckle unit includes at least a base, and a second connecting portion for engaging to or disengaging from the first connecting portion. An embodiment of the solution proposed here extends the \u201cConnecting without cables\u201d concept of Bluetooth to firmware upgrades.
