Dimmable window apparatus and vehicle including the same

Abstract:

A dimmable window apparatus is provided. The dimmable window apparatus includes a window including a first linear polarizing film and a second linear polarizing film, the first linear polarizing film and the second linear polarizing film having respectively a first axis of polarization and a second axis of polarization, the second axis of polarization being electronically-controllable. The apparatus further includes a processor coupled to the second linear polarizing film, and configured to control the second axis of polarization to thereby control the opacity of the window that is defined by the first axis of polarization and the second axis of polarization relative to one another.
