The Internet of Displays
An ever-increasing number of devices are connected to the Internet these days and an equally increasing number of devices are expected to have graphical user interfaces (GUIs) with touch screen functionality. To meet this demand, what is more logical than to come up with a wireless display with touch screen? Enter the Internet of Displays (IoD).

Australian smart display builder 4D Systems has done just that by introducing the gen4-IoD family of intelligent display modules with resistive touch and Wi-Fi capabilities. Together with the visual programming environment 4D Workshop the displays enable quick and easy creation of graphical user interface (GUI) applications with wireless connectivity. The Arduino IDE can be used too.

Powered by the well-known ESP8266 chip with built-in Wi-Fi, the display modules are able to handle demanding levels of graphics functionality while connecting and communicating with cloud services and other devices on the web.  An on-board SD card socket provides for extensive storage capabilities. Three sizes, all featuring a 240 x 320 pixel display, are available initially: 2.4”, 2.8” and 3.2”.
