The gen4 series, intelligent display modules from 4D Systems are designed specifically for ease-of-use and rapid development cycles, with careful consideration for space requirements and functionality. The gen4 series includes a variety of display sizes from 2.4" to 7.0" displays, available in non-touch, resistive-touch and capacitive-touch variations with an integrated cover lens bezel option. The gen4 series display modules are 100% compatible with 4D Systems’ Workshop4 IDE. Any application designed to run on other 4D Systems' display modules featuring the PICASO or DIABLO16 graphics processors can effortlessly be made to run on the gen4 series display modules with little or no modification requirements.

The gen4 series modules feature a 30-pin ZIF socket, designed for a 30-pin FPC, cable allowing easy and simple connection to an application or a mother board. All of the GPIO of the embedded PICASO or DIABLO16 graphics processors are accessible via the 30-pin FFC cable. The slim and streamlined design of the gen4 display modules minimize the impact of display-related circuitry and provide a platform that is suitable to integrate into virtually any application requiring a graphical user interface. As all of the display-related circuitry sit inside the plastic mounting base of the gen4 module, application boards can sit flush on the back of the gen4 display modules allowing for an overall slim and simplistic application design.

The gen4 series includes seven display sizes: 2.4", 2.8", 3.2", 3.5", 4.3", 5.0", and 7.0". Each display module is also available as a starter kit, including everything needed to get started with rapid GUI development. The modules are also available bundled with a 4D Arduino adapter Shield II and a 4D serial Pi adapter for easy integration with the Arduino and Raspberry Pi platforms.
