Low EMI multiplexed dual display

A mirror assembly having an electrically adjustable reflectivity and providing for the simultaneous display of information;

• the mirror assembly comprising:
• a mounting structure;
• a reflective device attached to the mounting structure, wherein the reflective device includes a transmissive element and a reflective surface formed on the transmissive element;
• a multiple element display for visually providing the information attached to the mounting structure;
• and
• a control circuit which provides for the variable attenuation of light through the transmissive element and controls the intensity and the information displayed by the multiple element display, the control circuit sequentially providing the information to the multiple element display, the control circuit exhibiting an electromagnetic interference level less than about 28 dBuV/m for narrowband emissions in the frequency range from about 0.4 MHz to about 20 MHz.
