1. A vehicular interior rearview mirror assembly, the vehicular interior rearview mirror assembly comprising:
a mirror head having a reflective element;
wherein the reflective element comprises a glass substrate having a transflective mirror reflector coated at a surface thereof, and wherein the transflective mirror reflector is partially reflective of visible light incident thereat and partially transmissive of visible light;
a display device disposed in the mirror head and behind the reflective element, wherein the display device comprises a video display screen that is operable to display video images that are viewable through the transflective mirror reflector of the reflective element;
wherein, with the vehicular interior rearview mirror assembly attached at an interior portion of a vehicle, the mirror head is adjustable between (i) a mirror mode orientation, in which the video display screen is not displaying video images and a driver of the vehicle views rearward of the vehicle using the transflective mirror reflector of the reflective element, and (ii) a display mode orientation, in which the video display screen is displaying video images viewable by the driver of the vehicle through the transflective mirror reflector of the reflective element;
wherein, with the vehicular interior rearview mirror assembly attached at the interior portion of the vehicle, and with the mirror head is in the display mode orientation, the video display screen displays video images derived from video image data captured by a camera of the vehicle viewing exterior the vehicle;
an actuator, wherein the actuator comprises an electrically-operable motor that, when operated, moves a cam follower of the actuator;
wherein the cam follower of the actuator has a groove that is traveled along by a pin disposed at the mirror head, and wherein operation of the electrically-operable motor moves the cam follower to cause the pin to travel along the groove to adjust orientation of the mirror head;
wherein, with the mirror head in the mirror mode orientation, and responsive to an input to adjust the mirror head to the display mode orientation, a first voltage is applied to cause the electrically-operable motor to adjust the mirror head out of the mirror mode orientation;
wherein, with the mirror head adjusted out of the mirror mode orientation, a second voltage is applied to cause the electrically-operable motor to adjust the mirror head toward the display mode orientation;
wherein, after the mirror head is adjusted toward the display mode orientation, a third voltage is applied to cause the electrically-operable motor to adjust the mirror head into the display mode orientation; and
wherein the second voltage is a lower voltage than the first voltage, and wherein the second voltage is a lower voltage than the third voltage.
