REARVIEW MIRROR ASSEMBLIES WITH ANISOTROPIC POLYMER LAMINATES

摘要

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 the SMS to a field-of-view (FOY) outside the assembly An SMS includes at least two electro-optic (EO) cells, one of which corresponds to the outside of the assembly and is adapted to be a switchable linear absorptive polarizer thereby configuring the 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 FOY in ambient light The SMS further includes first and second linear reflective polarizer laminates situated on two sequentially disposed substrates such as to sandwich an EO-medium of the second EO-cell between said first and second linear reflective polarizer elements, the laminates being devoid of extended distortion
