A vibrant, highly concentrated 4" (640 x 400 pixel) 7 colour electronic paper display for Raspberry Pi.
New ePaper screens just keep getting better! We can't resist them with their delicious crispness, impressive low power credentials and enticing viewing angles (even in bright sunlight). This 4" eInk display is positively bulging with pixel density and bright strong colours, and Pimoroni has fitted it with all the necessary apparatus to interface with a Raspberry Pi cleanly, humanely and without fuss.
In addition to the resources below, Tim from Core has published an excellent guide on making the most of these displays, and even how to stick them in a photo frame for an awesome ever-changing desk decoration!
Inky Impression 4" is comparable in size to our 3 colour Inky wHAT, but it's got a number of advantages over ol' wHATty:
eInk displays only consume power whilst refreshing, so they're a good choice for things like home automation dashboards and calendar displays that are always on. Pimoroni has found these 7 colour displays do a really nice job of displaying art too - especially stylised, bold images like pop art and children's drawings.
This screen takes around 15 seconds to refresh, so is best suited to projects that don't rely on constant screen updates. Please note that it's not possible to change the colour of the purple border on this screen using software, like with some Inky displays.
Multi-colour EPD displays use electrophoresis to pull coloured particles up and down on the display. The coloured particles reflect light, unlike most display types, meaning that they're visible under bright lights. It takes approximately 15 seconds to refresh the display.
Everything comes fully-assembled, and there's no soldering required! The display is securely stuck down to the Inky Impression PCB and connected via a ribbon cable. Just pop Inky Impression on your Pi and run our installer to get everything set up!
Pimoroni has also broken out the I2C pins on the back of Inky Impression, letting you connect additional devices like breakouts and show their data right on the display.
Inky Impression will work with any version of the Pi with a 40 pin header, including Zero variants. If you want to use it with a Raspberry Pi 400, you'll probably also want to pick up a GPIO extender cable (unless you're into using screens at a highly unusual angle).
Our Python library takes the stress out of displaying text and images on Inky Impression, and Pimoroni has put together a few new examples to show off Inky Impression's capabilities. Pimoroni has put together a one-line-installer for the Python library too, to make installation a little more straightforward:
