This is a huge step in E-Paper technology! These screens have all the benefits of electronic paper, including excellent battery life, image retention when un-powered and great visibility in sunlight, but they are finally multi-coloured. Also I make an auto-changing E-Ink Picture Frame 😊

Electronic Ink is a familiar technology to everyday makers. They are low power displays that have great visibility in sunlight and preserve the displayed image even when not powered. Once you display an image to the screen it will stay there for ages, up to weeks, completely without electricity. Commonly applications have been signage, E-readers or simple project dashboards. The technology refreshes slowly so it’s never been for fast updating user interfaces. Up until recently the technology has been limited to monochrome with a single colour. But no longer! Welcoming in the Inky Impression 5.7" 7 Colour, 600x448 Pixel E-ink/E-paper HAT capable of running with a Raspberry Pi Single Board computer. Thats right! Seven colours! They are Blue, Green, Red, White, Yellow, Orange, and Black. Combine these block colours with dithering, a method used by computers to approximate unavailable colours from a mixture of other colours, this Electronic Ink display can produce to the human eye all the colours! HAT means simply Hardware Attached on Top.
This technology's full name is ACeP Micro Encapsulated Electrophoretic Displays. Inside every one of these screens are thousands of tiny oil bubbles with colourful charged particles. Depending on the current flowing above or below these oil filled bubbles certain particles are drawn up or down. When the particles are drawn to the top of their oil filled bubble we can then see their colour displayed on the E-Ink screen. Its so cool! It's ink, but way better. Huge shout out to Pimoroni! From hardware assembly to image display tinkering this has everything you need to hit the ground sprinting with these displays.
