2.83" AMOLED Display

  • Powerful Graphics
  • 65K True to Life Colours
  • AMOLED Technology
  • Resistive Touch or Non-Touch

The uOLED-32028-P1(T) is a compact and cost effective all in one Intelligent Display Module using Active Matrix OLED (AMOLED) technology with an embedded PICASO graphics controller that delivers "stand-alone" functionality to any project.

The 2.83" AMOLED display is a very high quality, high viewing angle, crisp and clean viewing display that is suited to a large range of applications.

Embedded at the heart of the design is the PICASO processor, which is driven by a highly optimised virtual core engine called EVE (Extensible Virtual Engine). An extensive range of hardware and software peripherals have been integrated into the design, to give the user freedom to adapt the module to suit almost any application.

The uOLED-32028-P1(T) is a clever combination of a 2.83" (240x320) AMOLED Display, audio amplifier and speaker, micro-SD card connector, along with a group of general purpose input/output pins (GPIO's), including I2C and serial COMMS.

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.

The Display Modules PICASO processor can be re-programmed with the latest PmmC/Firmware as updates or bug fixes are made available. This process is conducted via the Workshop 4 IDE Software, and requires a 4D Systems approved programming cable or adaptor.
