UPDATED PRODUCT – 2.13″ 212×104 Flexible Monochrome / 4-Gray eInk ePaper Display – ILI0373 Chipset

---

Woah, the cyber-future is here! Flexible E-Ink has been demo’d at high-tech events for years but now you can actually get your paws on it. This display is true E-Ink / E-Paper, once an image is displayed it will stay even once you remove all power. The image is also high contrast and very daylight readable. It really does look just like printed paper!

This flexible display sports a 2.13″ monochrome or 4-grayscale display. It has 212×104 ink pixels on a white-ish background. The ILI0373 chipset we now use does have some basic grayscale so you can have white, light gray, dark gray and black. The monochrome displays take only a couple of seconds to update.

Please note: this display is flexible but that doesn’t mean you can constantly flex it. The video above showing a hand twisting the display is a looped demo, not an instructional video.

• These displays should not be flexed/moved during a display update, you’ll get odd effects.
• Continuously flexing it will eventually damage the display.
• There’s no specification for how many times it can be flexed, so keep it minimal!
• We recommend affixing the display to a stable backing to reduce stresses. E.g. it can be attached to a stiff curved bracelet to make a watch.
• Don’t flex where the orange connector cable meets the eInk display – the chip is very delicate and you could crack the connections
• You can flex the orange connector cable a few times, it’s made of flex PCB with a 2-3mm radius.
• You can flex the eInk display with, perhaps, a 10mm radius… this isn’t documented, just experimental!

Using our CircuitPython or Arduino libraries, you can create a ‘frame buffer’ with what pixels you want to have activated and then write that out to the display. The 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: This is just the display. You’ll want your own eInk Breakout Friend too!
