• "The circuit is called a bistable because it is stable in two states: output high and output low."
• "It is based on a reflective MEMS-based technology, inspired from butterfly iridescence, called interferometric modulation, or IMOD for short, which "is both bistable, meaning it is both extremely low power, and highly reflective, meaning the display itself can be seen even in direct sunlight," according to the official website."
• "Like an E-Ink pixel, each Mirasol subpixel is bistable, meaning that it's stable in either the "open" or "closed" states, and it requires power only to switch states; this bistability gives it its low-power characteristics."
