I'm not a materials scientist or display engineer, but the full paper[1] seems to describe something very different from an IMOD display. * IMOD is a reflective display. This display is a replacement for the LCD layer in LCD displays, but still seems like it would require a backlight. * The pixels in this display are controlled via heating to change the optical properties of the silicon. The pixels in IMOD are switched by moving a reflective membrane very slightly in relation to a thin film stack - a MEMS analogue of the radar-absorbing skin of stealth aircraft. * IMOD doesn't require power to maintain the state of a given pixel, only to switch it. Since the metasurface display is controlled by heating, I imagine one state or the other (not sure if it's the "allow light through" or "block light" state) needs to be refreshed constantly.
