Abstract
The disclosure generally pertains to a visor system of a vehicle. The visor system may include a multifunctional visor having a multilayer stack. A first layer of the multilayer stack may include a material whose optical transmittance is modifiable in response to a control signal provided by a controller, a second layer containing a material whose optical reflectance is modifiable in response to another control signal provided by the controller, and a third layer, which is interposed between the first layer and the second layer and includes a display system that turns optically transparent in response to another control signal provided by the controller. An occupant of the vehicle can make a selection to place the multifunctional visor in any of various states, such as a mirror state, a visor state, or a display state (for displaying images such as a speedometer and/or a GPS route map).
