Pervasive Displays e-Paper Screens

E-paper screens only require power to change the display. Otherwise, they need no power supply: this feature makes them the ideal solution for ultra-low-power applications.

Pervasive Displays offers a wide range of e-paper screens, with two colours in black and white, three colours in black-white-red or black-white-yellow, or four colours black-white-red-yellow.

A new version of the 2.71" monochrome screen offers fast display, more than 3.5 times faster, reviewed at Pervasive Displays e-Paper Screen with Fast Update.

EPDK all-in-one kits

The Pervasive Displays E-Paper Display Pico Kit Touch (EPDK-271-Touch) adds touch to the e-paper technology to explore ultra-low power human-machine interfaces.

On the software side, the Pervasive Displays Library Suite has been updated for Arduino and is also available for Python.

The Pervasive Displays E-Paper Display Pico Kit (EPDK) includes everything to start exploring the e-paper technology, including the popular Raspberry Pi Pico board.

Latest generation EXT3-1 and EXT3-Touch

The last revision of the EPD Extension Kit Gen 3-1 comes with an expansion board for touch and brings a whole new dimension to e-paper displays.

Instead on being passive devices, e-paper displays are now active input devices, perfectly suited for ultra-low power human-machine interfaces.

Connecting the e-Paper EPD Extension Kit Gen 3-1 is as easy as counting from 1 to 10.

Assembing the Pervasive Displays EXT3-Touch requires four more connections, thus counting up to 14.

Pervasive Displays Library Suite

The Pervasive Displays Library Suite is specifically designed for the Pervasive Displays screens and boards.

It provides a high-level interface to drive the e-paper screens with global and fast update, supports capacitive touch and haptic feed-back.

It is developed in C++ and relies on the Arduino SDK. It could easily be ported to any other SDK.

The User guide focuses on how to use the different libraries, with commented examples. The Reference manual lists all the objects and functions, with details for their parameters and returned results.

Previous generations

The screens are driven by the Pervasive Displays e-Paper EPD Extension Kit Gen 3. The compact board is universal and connects to any controller through SPI. The section Connecting the e-Paper EPD Extension Kit Gen 3 provides examples for popular boards.

It replaces the previous generations Pervasive Displays e-Paper EPD Extension Kit Gen 2 and Pervasive Displays e-Paper EPD Extension Kit in BoosterPack form-factor for the LaunchPad boards.

I also designed my own FRAM-based E-Paper Screen Controller.

Connecting the e-Paper EPD Extension Kit Gen 3 is as easy as counting from 1 to 10.
