Intelligent touch-display modules have integrated WiFi

March 15, 2017 // By Graham Prophet
4D Systems (Sydney, Australia) has designed the gen4 Internet of Displays (IoD) series of intelligent display modules with resistive touch. With integrated WiFi capabilities, the display modules offer a simple route to create GUI applications with wireless connectivity.

Three sizes are available initially, the 2.4 in. gen4-IoD-24T, the 2.8 in. gen4-IoD-28T, and the 3.2 in. gen4-IoD-32T. All feature a 240 x 320 pixel display with resistive touch and integrated WiFi.

The display modules are aimed at manufacturers and enthusiasts who need a quick and easy-to-use professional solution for wireless GUI applications. Hosting an ESP8266 SoC device (Espressif, Shanghai), the modules are able to handle very demanding levels of graphics functionality, and with wireless connectivity they are able to connect and communicate with cloud data and other devices on the web. An on-board SD card socket enables the use of FAT16 or FAT32 formatted cards for storage capabilities. The display modules provide the ability to design a GUI using Workshop4 IDE or Arduino IDE software. This enables drag and drop type programming, and eliminates the need to perform traditional coding.

 

The modules utilise novel manufacturing processes that provide for cost savings with build quality. In normal use the modules can be fitted into very small end user application enclosures. Or, application boards can sit flush at the back of the module allowing for very compact end user applications. The modules employ 4D Systems’ main software development tool – 4D Workshop4 IDE. This development environment provides users with the possibility to quickly develop GUIs for embedded displays with minimal coding requirements. Users can see what they are developing during the development process, and the software takes care of most of the coding for the graphics.
