Zero-field bistable display, no need to refresh and no need for backlight, which really takes advantage of the micro-power consumption of liquid crystal display.
It adopts reflected light display, is easy to realize color, and is readable in sunlight, suitable for outdoor display.
No polarizing plate is needed, which greatly improves the display brightness.
Under zero electric field, each pixel of the display can be stabilized in different reflection states for a long time.
The drive circuit is relatively simple, and especially suitable for e-books, electronic curtains and commercial advertising.
