EPD (Electronic Paper Display) technology is defined as bistable. This means that each e-paper matrix cell may occur in one of two available states and no electrical energy is required to maintain displayed content, e.g. cells in black-and-white display arrange in a way to display black (state ‘0’) or white (state ‘1’) color. Energy is only needed to change the cells position, simplifying – to change the display image. Thanks to this feature, EPD technology is a perfect solution in applications where content is changed relatively rarely (e.g. e-prices, e-timetables, e-readers, smart watches and more).
