1. A switchable mirror system (SMS) for use in a vehicular rearview assembly equipped with a light source transmitting light from within the rearview assembly through said SMS to a field-of-view (FOV) outside the assembly, the SMS comprising:

  • at least two electro-optic (EO) cells defined by at least three sequentially disposed spaced-apart substrates, a first EO-cell corresponding to an outside portion of the rearview assembly and a second EO-cell disposed between the first EO-cell and the light source,wherein the first EO-cell is adapted to be a switchable linear absorptive polarizer thereby configuring said SMS to have a reflectance value that is gradually variable in response to changes in voltages applied to the first and second EO-cells, as measured in said FOV in ambient light.
