Description
The 4Discovery-5.0 is a high resolution 480x854 pixel 4.95” (referred to as 5.0”) Intelligent wall mounted display product from 4D Systems, featuring the DIABLO16 Processor.
The 4Discovery’s 5” TFT display is IPS, giving it very wide viewing angles.
The 4Discovery is designed to be mounted directly onto a panel or wall, or any flat drillable surface. This universal mounting enables quick and easy installation almost anywhere in any orientation, enabling a wide range of customers to take advantage of this display product.
Driving the display and peripherals is the DIABLO16 processor, a very capable and powerful graphics processor from 4D Labs, which enables stand-alone functionality, and is programmed using the 4D Systems Workshop 4 IDE Software. The Workshop IDE enables graphic solutions to be constructed rapidly and with ease due to its design being solely for 4D’s graphics processors.
The 4Discovery has an array of features including a 5.0” 480x854 pixel TFT LCD Display, Capacitive Touch, micro-SD memory storage, optional Flash memory storage, 2 wire RS485 Interface which can act as Master or Slave with additional changeover wire, Proximity sensor to wake (or otherwise) the unit as someone approaches, and a switch-mode power supply enabling a wide input voltage range, optional WiFi/Bluetooth, along with many more features.
Anything that has been designed to run on a PICASO or DIABLO16 module can theoretically run on this 4Discovery with minor changes. Please ensure you contact the 4D Systems’ support team if unsure changing over from a 4D Systems’ module to this 4Discovery.
The 4Discovery-5.0 can be customised for customers who require alterations to the pinout or to add some extra features. The 4Discovery features a daughter board that is attached at the factory which can be modified to suit specific requirements, simply by changing the design of the daughter board. More details can be found in later sections on this topic.
For other customisations such as plastics colour, or for more detailed enquiries specific to your application, please contact the 4D Systems sales team.
