gen4 2.8" Diablo16 Intelligent Display Modules

The gen4 2.8” Diablo16 Integrated Display Modules are part of the latest gen4 series of modules Designed and Manufactured by 4D Systems.

The gen4 series was designed specifically for ease of integration and use, with careful consideration for space requirements and functionality.

These specific gen4 modules features a 2.8” colour TFT LCD display, and come with options for Cover Lens Bezel (CLB), and resistive touch. They is powered by the well-known 4D Systems Diablo16 Graphics Processor, which offers an array of functionality and options for any Designer / Integrator / User.

The 2.8” Diablo16 Integrated Display Module features a TFT LCD Display, is capable of Touch Detection, microSD memory Storage, GPIO and Communications, along with multiple millisecond resolution timers, and Audio Generation.

The gen4 Series is 100% compatible with the Workshop4 IDE and its 4 different development environments, providing the User with a wealth of options for programming and controlling their system.

The gen4 series of Integrated Display Modules features a 30 pin ZIF socket, designed for a 30 pin FPC cable, for easy and simple connection to an application or mother board, or for connecting to accessory boards for a range of functionality advancements.

The gen4 series of modules has been designed to minimise the impact of display related circuitry, and provide a platform suitable for integration into a product. Application boards can sit flush on the back of the gen4 if required, as the display related electronics sit inside the plastic mounting base, leaving the application board surface clear for User circuitry.

Models in this size:
gen4-uLCD-28D (non Touch, without Cover Lens Bezel)
gen4-uLCD-28DT (Resistive Touch, without Cover Lens Bezel)
gen4-uLCD-28D-CLB (non Touch, Cover Lens Bezel)

Introducing 4D Systems' All New Workshop4 IDE

Supports multiple development environments, to cater for different user requirements and skill level.

Workshop4 is a comprehensive software IDE for Microsoft Windows that provides an integrated software development platform for all of the 4D family of processors and modules. The IDE combines the Editor, Compiler, Linker and Downloader to develop complete 4DGL application code. All user application code is developed within the Workshop4 IDE.

Workshop4 includes four development environments, for the user to choose based on application requirements or even user skill level.

This environment enables the
user to write 4DGL code in its
natural form to program the
display module.


ViSi - Genie

An advanced environment
that doesn't require any
coding at all, it is all
automatically for you.
lay the display out
with the 
objects you want
(similar to 
ViSi), set the
events to drive 
them and
the code is written 
you automatically. ViSi
Genie provides the latest
rapid development
experience from
4D Systems.



This environment is also
provided to transform the
display module into a
slave serial display module,
allowing the user to control
the display from any host

microcontroller or device
with a serial port.

A visual programming
experience that enables
drag-and-drop type

placement of objects
to assist with 4DGL code
generation and allows

the user to visualise how
the display will look while
being developed
