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 2.9″ monochrome (black and white) display. It has 296×128 black ink pixels on a white-ish background. The monochrome displays also take a lot less time to update, only a couple seconds instead of 15 seconds.
Please note: this display is flexible but that doesn’t mean you can constantly flex it.
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.
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. Most simple breakouts leave it at that. But if you do the math, 296 x 128 pixels = 4.7 KBytes. Which won’t fit into many microcontroller memories. Heck, even if you do have 32KB of RAM, why waste 5KB?
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
