NEW PRODUCTS – 3.7″ 416×240 Tri-Color & 3.7″ Monochrome eInk / ePaper Bare Displays
E-Ink/E-Paper displays make for great low-power displays that are daylight visible and keep their image even when depowered. For folks who want to DIY their own E-Ink setups, this is a 3.7″ diagonal Tri-Color (Red, Black, White) eInk / ePaper Bare Display with 416 x 240 pixels.
Chances are you’ve seen one of those new-fangled ‘e-readers’ like the Kindle or Nook. They have gigantic electronic paper ‘static’ displays – that means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper!
Please note: this is the bare display element. You need to plug it into a board with a ‘standard’ 24-pin FPC e-paper connector. We recommend checking out and picking up a matching driver board:
- Feather RP2040 ThinkInk – solderless plug-and-play solution with Arduino or CircuitPython support. Definitely the easiest way to get started, and is what we show in the demo above
- eInk Feather Friend – FeatherWing add-on for any Feather board)
- eInk Breakout Friend – breadboard-friendly adapter that gives you level-shifting and components for quick eInk connectivity.
- 24-pin eInk / ePaper Extension Cable + 24-pin FPC adapter – both together will give your eInk display a stretch so you can place it anywhere.
This is a 3.7″ tri-color display. It has 416×240 red or black ink pixels and a white-ish background. It uses the UC8253 chipset, so make sure whatever firmware code you are planning to use has support for it. The Arduino library we wrote does all the work for you; you can just interface with it as if it were an Adafruit_GFX compatible display.
Note that you cannot overlay/mix pixels: each point can be one of the three ‘colors’, but you can’t mix the red and black to make an orange. Instead, check out our guide on dithering!
