I wanted to save power over LED displays and came across ynvisible' s line of electrochromic displays, these are not your off the shelf displays as there currently made to order but I have suggested to them that maybe they should create some standard displays and sell them as a line, this way people can get to use them without needing thousands to get a good price.
They use perhaps 1 microwatt per cm2 compared to 400mW for LED,

They kindly sent me a kit to play with so here is the initial look, testing with their provided modules, driver boards and code, in the next video I will demonstrate how easy they are to interface using a standard Arduino Uno.
