Future Trends in Power Management
The low power advantage of the IMOD display is due to the mechanical structure of
the IMOD pix
el. There is a hysteresis effect in the electro-optical function of the IMOD
display. As a result, it requires very little power to maintain either one of its two states.
This feature, called bistability, allows a display constructed of IMOD pixels to maintain
an image with near-zero power consumption.
The IMOD element provides functionalities that would require three separate elements
in an LCD, each of which require multiple processing steps. First, the modulation is
accomplished via the mov ...
