     FIELD OF THE INVENTION 
     The present invention relates generally to the field of interior rearview mirror assemblies for vehicles and, more particularly, to interior rearview mirror assemblies with a display. 
     BACKGROUND OF THE INVENTION 
     It is known to provide a mirror assembly that is adjustably mounted to an interior portion of a vehicle, such as via a double ball pivot or joint mounting configuration where the mirror casing and reflective element are adjusted relative to the interior portion of a vehicle by pivotal movement about the double ball pivot configuration. The mirror casing and reflective element are pivotable about either or both of the ball pivot joints by a user that is adjusting a rearward field of view of the reflective element. It is also generally known to provide a display screen at the mirror assembly. The mirror assembly may include a video display screen disposed in the mirror casing behind a display portion of the reflective element so as to be viewable, when activated, through a transflective mirror reflector of the reflective element. 
     SUMMARY OF THE INVENTION 
     The present invention provides an interior rearview mirror assembly that includes an electro-optic mirror reflective element and a display device operable to display information for viewing by the driver of the vehicle. The display screen of the display device substantially spans the height and width of the mirror reflective element. The reflective element and display are part of a mirror head or display and reflective element assembly that is rotatable about 180 degrees about a generally horizontal axis, such that, when in a mirror position, the mirror assembly has the reflective element facing the driver of the vehicle, and in a display position (about 180 degrees rotation from the mirror position), the display device is facing the driver of the vehicle. 
     Thus, the present invention provides a mirror reflective element and display assembly that allows for enhanced reflectance at the mirror reflective element (since the reflective element does not have to be transmissive to allow for viewing of the display device through the reflective element) and that provides enhanced viewing of the displayed images (since they are not attenuated by passing through a partially transmissive reflective element). 
     These and other objects, advantages, purposes and features of the present invention will become apparent upon review of the following specification in conjunction with the drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring now to the drawings and the illustrative embodiments depicted therein, an interior rearview mirror assembly  10  for a vehicle includes a mirror head or mirror and display assembly or mirror-display assembly  12  that includes a reflective element  14  and a display device  16 , which provides a display area visible to the driver of the vehicle through the reflective element  14  ( FIGS. 1 and 2 ). The mirror assembly  10  is configured to be adjustably mounted to an interior portion of a vehicle (such as to an interior or in-cabin surface of a vehicle windshield or a headliner of a vehicle or the like) via a mounting structure or mounting configuration or assembly. The mirror head  12  of the interior rearview mirror assembly  10  may house all or a portion of the components of the interior rearview mirror assembly  10  and may be integrally formed with portions thereof. 
     The mirror head  12  comprises the display device  16  on one side and the reflective element  14  at the other side. The reflective element may comprise any suitable reflective element, such as an electro-optic (such as electrochromic) variable reflectance reflective element or such as a prismatic reflective element. The reflective element need not have a transflective (partially reflective and partially transmissive) mirror reflector, since the display screen is not viewable through the reflective element. As shown in  FIG. 2 , the mirror head may also include electronics  18  (such as a glare sensor, an ambient light sensor, a camera, electro-optic drive circuitry, display circuitry, lights, and/or the like) disposed in a space between the reflective element  14  and the display device  16 . A bezel or surround structure  20  may be disposed about the periphery of the reflective element  14  and the display device  16  to secure the elements together and to encase or enclose the central cavity where electronics  18  or the like may be disposed. 
     Electrical connection to the electronics  18  may be provided via one or more wires that may pass through the bezel  20  to a mounting connection of a mounting structure  22  ( FIG. 5 ). The electrical connection allows for rotation of the mirror head  12  relative to the mounting structure  22  while maintaining electrical connection to the electronics  18 . For example, the electrical connection may comprise wires that have sufficient play to allow for twisting in one direction or the other (where pivotal movement of the mirror head may be mechanically limited to about 180 degrees) or the electrical connection may comprise a sliding contact that may allow for full 360 degrees of rotation of the mirror head relative to the mounting structure  22 . 
     In the illustrated embodiment, the mirror head rotates around a generally horizontal axis. There is no housing, but rather has a video display screen on one side and a mirror reflective element on the other side. The electronics and wiring is disposed between the display device and the reflective element and surrounded by the bezel. The bezel may provide curved perimeter edge regions so as to provide a smooth curved transition between the front (viewed) surface of the reflective element and the side wall or surface of the bezel and to provide a smooth curved transition between the front (viewed) surface of the video display screen and the side wall or surface of the bezel. The bezel is disposed around the assembly to cover all the connections. The wiring can be routed at the point where the mirror connects to the frame or mounting structure. 
     When the mirror head is pivoted to the display orientation or position, the reflective element may face forward in the direction of travel of the vehicle and thus would be facing traffic approaching the equipped vehicle. Thus, it is desirable to provide a masking element that may be disposed in front of the mirror head so as to block the reflective element (and the display device when the mirror head is in the mirror position) from view by drivers of other vehicles ahead of or approaching the equipped vehicle. Optionally, and such as can be seen in  FIG. 3 , the mirror reflective element may not be parallel or aligned with the display screen, such that, when the mirror head  12 ′ is in its display orientation (with the display device  16 ′ at the desired angle for viewing by the driver of the vehicle), the reflective element  14 ′ (now facing forwardly towards leading and oncoming traffic) is angled upward toward an upper portion of the vehicle windshield (or optionally the mirror head may be constructed so, when in the display position, the reflective element is angled downwardly). In such a configuration, the assembly may have to be able to rotate or pivot more than about 180 degrees to pivot between the display position and the mirror position. Optionally, and desirably, the mirror reflective element may be angled at least about 10 degrees relative to the display device, and optionally at least about 20 degrees, and optionally at least about 30 degrees relative to the display device, in order to have the reflective element angle sufficiently upward or downward when the mirror head is in the display mode or position. Optionally, it is envisioned that the reflective element may be generally orthogonal to the display device, such that the mirror head rotates about 90 degrees (or other suitable angle) between the display position and the mirror position (whereby the depth of the mirror head increases, such that clearance for such a construction would be needed at the mounting structure and windshield). 
     As shown in  FIG. 5 , the mirror head may be pivotally mounted at a mounting structure  22  that allows for rotation of the mirror head about a generally horizontal pivot axis (or optionally that allows for rotation of the mirror head about a generally vertical pivot axis). The mounting structure may pivotally mount at an interior portion of the vehicle so that the mounting structure may pivot about a generally vertical axis (or any axis generally orthogonal to the pivot axis of the mirror head at the mounting structure) so that the driver may readily adjust the mirror assembly to provide the desired rearward field of view when the mirror head is in the mirror mode or position. Optionally, the mounting structure may otherwise provide for multi-axis adjustment of the mirror head to allow the driver of the vehicle to adjust the position of the mirror head to provide the desired rearward field of view when the mirror head is in the mirror mode or position. 
     Optionally, the mirror head may be otherwise mounted at a mounting structure to allow for pivotal movement of the mirror head to allow for separate viewing of the mirror reflective element (when the mirror head is in a mirror mode or position) and the video display screen (when the mirror head is in a display mode or position). Optionally, the mirror/display assembly may be disposed at or partially in a mirror casing or housing with a small gap between the mirror head and the mirror casing to allow for the mirror to rotate or pivot. When such a mirror/display structure is in a housing (such as similar to a mirror reflective element of an exterior rearview mirror assembly) where there is a gap between the mirror reflective element and the housing to allow for the adjustment and pivoting or rotating of the mirror head, there is no concern about reflection off the mirror reflective element (when the mirror head is in the display position) into oncoming traffic. 
     Thus, the mirror head is pivotable to adjust or position the mirror head between a mirror mode or position (where the driver of the vehicle views the mirror reflective element for rearward viewing, and where the mirror head may be adjustable about multiple pivot axes to allow for adjustment of the rearward field of view for the particular driver) and a display mode or position (where the driver of the vehicle views the video display screen). The mirror head may be automatically pivoted or rotated (such as via a motor or actuator at the mirror mounting structure or the like) between the mirror mode and the display mode, such as in response to a user input or the like (for example, a user may press a button or toggle to switch between the modes, or the system may automatically rotate the mirror head to the display mode when the vehicle is shifted into reverse gear for a backup assist camera system). If there is a power failure or actuator failure, the driver can manually rotate the mirror head to the mirror mode or position so that the mirror reflective element is viewable by the driver and can be used for normal driving. 
     Optionally, the mirror head may be manually pivoted or rotated by the driver as desired. Optionally, and desirably, the display device is only activated for displaying images when the mirror head is in the display mode or position and is not operable when the mirror head is in the mirror mode or position. Similarly, the electro-optic mirror reflective element may only be operated when the mirror head is in the mirror mode or position and may not be operable (such that the glare light sensor may be deactivated and the electro-optic control circuitry may be deactivated) when the mirror head is in the display mode. 
     Referring now to  FIGS. 6-20 , an interior rearview mirror assembly  110  for a vehicle includes a mirror head  112  that includes a reflective element  114  and a display device  116 , with the mirror head  112  pivotally mounted at a mounting structure  122  and pivotable about a generally horizontal axis (or an axis extending longitudinally along a length axis of the mirror head) between a mirror orientation ( FIGS. 6, 9-11, 13, 15 and 17-20 ) and a display orientation ( FIGS. 7, 8, 12, 14 and 16 ). The mirror head  112  comprises the display device  116  on one side and the reflective element  114  at the other side. The reflective element may comprise any suitable reflective element, such as an electro-optic (such as electrochromic) variable reflectance reflective element or such as a prismatic reflective element. The reflective element need not have a transflective (partially reflective and partially transmissive) mirror reflector, since the display screen is not viewable through the reflective element. As shown in  FIGS. 9-12 , the mirror head may also include electronics  118  (such as a glare sensor, an ambient light sensor, a camera, electro-optic drive circuitry, display circuitry, lights, and/or the like) disposed in a space between the reflective element  114  and the display device  116 . A bezel or surround structure  120  may be disposed about the periphery of the reflective element  114  and the display device  116  to secure the elements together and to encase or enclose the central cavity where electronics  118  or the like may be disposed. 
     Electrical connection to the electronics  118  may be provided via one or more wires  124  that may pass through the bezel  120  to a mounting connection of a mounting structure  122  ( FIGS. 10 and 11 ). The electrical connection allows for rotation of the mirror head  112  relative to the mounting structure  122  while maintaining electrical connection to the electronics  118 . For example, the electrical connection may comprise wires that have sufficient play to allow for twisting in one direction or the other (where pivotal movement of the mirror head may be mechanically limited to about 180 degrees) or the electrical connection may comprise a sliding contact that may allow for full 360 degrees of rotation of the mirror head relative to the mounting structure  122 . 
     In the illustrated embodiment, the mounting structure  122  comprises a generally U-shaped bracket  122   a  that pivotally attaches at its ends to the opposite ends of the mirror head  112 . The bracket  122   a  pivotally mounts at a pivot joint  122   b  at a mirror mount  122   c.  The pivot joint  122   b  comprises a ball and socket pivot joint. The mirror mount  122   c  is configured to attach at an interior portion of a vehicle, such as at a header of the vehicle or such as at an interior surface of the vehicle windshield. 
     As shown in  FIGS. 10-12 and 17 , the mirror head  112  includes a motorized actuator  126  that, when powered (such as via a user input or vehicle input), pivots the mirror head relative to the bracket  122   a.  The motor of the actuator may be disposed at the circuit board in the mirror head and may rotatably drive one or more gears that engage a geared or toothed pin at the bracket  122   a,  such that rotational driving of the gears causes pivotal movement of the mirror head relative to the bracket  122   a.    
     The mirror-display assembly of the present invention thus provides enhanced mirror-based display that includes increased brightness of the display (since the display is not displaying through a transflective reflective element), and provides for such increased brightness with decreased power for driving the display backlight or LED array. By moving the EC cell so that it is not in front of the display when display is on, the system increases the efficiency by about four times and reduces the amount of power needed to power the backlight. Optionally, the mirror assembly may include an edge light backlight with less LEDs, better uniformity, less films, and thinner backlight design. The assembly also reduces the amount of display ghost images caused by the different surfaces of the EC cell. Also, because the display is not viewed through the electrochromic (EC) cell, the EC cell does not need display on demand (DOD) transflective coatings (that are partially reflective and partially transmissive of light incident thereat). This provides for enhanced uniformity of the reflective surface of EC (and does not require any window for display). 
     The mirror assembly provides for flipping of the entire mirror head to selectively position the mirror reflective element or the display screen for viewing by the driver of the vehicle. The mirror head may be flipped or rotated via a manual flipping function with a friction or detent clutch, or may be powered with a motor (that preferably includes a manual override so the driver can manually pivot the mirror head to the desired orientation. The manual version may include a gravity switch in the mirror head that automatically turns on the display when the mirror head is pivoted or flipped to the display orientation. Optionally, and such as shown in  FIG. 21 , the reflective element may be at an angle relative to the display screen to adapt the mirror head to provide a direct view of the display screen when the mirror head is in the display orientation and an angled view of the reflective element when the mirror head is in the reflecting mirror orientation. Thus, when the mirror head is flipped between the mirror and display orientations, the driver need not laterally adjust the mirror head and bracket relative to the mirror mount. Optionally, the mirror head may be pivotable about a generally vertical axis (or axis normal to the rotational axis or flip axis) to adjust the mirror head laterally when the mirror head is flipped between the mirror and display orientations. 
     Thus, the mirror assembly includes an actuator that preforms the rotation of the mirror head to provide the desired function (mirror or display) for viewing by the driver of the vehicle. When the user actuates a user input or switch or button, the actuator pivots the mirror head to the display orientation and the digital display turns on and displays images for viewing by the driver of the vehicle (such as video images derived from image data captured by a camera of the vehicle). As can be seen with reference to  FIGS. 15 and 16 , when the mirror-display assembly is in the display mode or orientation ( FIG. 16 ), the driver can view the displayed rearward scene without obstructions, such as rear window elements and headrests and the like, that are viewed in the reflection at the mirror reflective element when the mirror-display assembly is in the mirror mode or orientation ( FIG. 15 ). Optionally, the mirror head may automatically pivot to the display orientation responsive to the driver of the vehicle shifting the vehicle transmission into a reverse gear, whereby video images captured by a rear backup camera may automatically be displayed at the display screen for viewing by the driver during a reversing maneuver. 
     Optionally, the mirror head may provide a display and mirror reflective element or EC cell, with the EC cell being flipped via a spring-loaded push-push latch (or powered via a motor). 
     Optionally, the mirror and display construction may otherwise selectively position the mirror in front of the display and the display in front of the mirror. For example, the mirror display may be assembled directly in front of the reflective mirror, whereby the display could be flipped, slid and/or removed to reveal the reflective mirror, or the reflective mirror could be in front of the display, whereby the reflective mirror could be flipped, slid and/or removed to reveal the display. 
     The mirror and display may utilize aspects of the mirrors and displays described in PCT Application No. PCT/IB2017/052542, filed May 2, 2017 (Attorney Docket DON01 FP-3034(PCT)), and/or U.S. Publication No. US-2016-0375833 and/or U.S. patent application Ser. No. 15/585,419, filed May 4, 2017 (Attorney Docket DON01 P-3024), and/or U.S. provisional applications, Ser. No. 62/501,263, filed May 4, 2017, Ser. No. 62/476,951, filed Mar. 27, 2017, Ser. No. 62/471,492, filed Mar. 15, 2017, Ser. No. 62/466,089, filed Mar. 2, 2017, and/or Ser. No. 62/355,460, filed Jun. 28, 2016, which are all hereby incorporated herein by reference in their entireties. 
     Optionally, a camera and/or a non-image sensor may be disposed in the vehicle that views or senses through the windshield of the vehicle or through the rear window of the vehicle. Optionally, the windshield and/or rear window may include a clear portion (non-tinted) to enhance viewing or sensing by the camera/sensor. This allows as much light to get to the camera as possible. Often, for example, rear windows are tinted so as to have a dark tint that is typically impregnated into the glass, which hinders mounting the rearward viewing camera inside the rear window. By having a small portion or window within the window that did not have this tint, this mounting position could be better utilized. Also, by having the camera at that location (behind the window), the camera can be kept free of contamination and water droplets as the window would be cleaned by the rear window wiper/sprayer system. 
     Optionally, the windshield may have a window or region where there is no IR/UV blocking, such as for use with a LIDAR sensor mounted behind the windshield (such as at the mirror head or bracket or mirror mount or windshield accessory module or the like). Such optical sensors are not typically mounted behind the windshield because of the IR/UV blocking characteristics of the vehicle windshield. 
     Aspects of the present invention may also be used in video mirrors such as those described in U.S. Pat. No. 9,057,875 and/or in U.S. Publication No. US-2014-0347488, which are hereby incorporated by reference herein in their entireties. In such video mirrors that utilize a full-screen or near full-screen video display, an actuator device is adjustable to tilt a mirrored glass element in one direction, thereby moving the mirrored glass element to an off-axis position which approximately simultaneously changes the on/off state of a video display module. The actuator device is also adjustable to tilt the glass element in another direction, thereby moving the glass element to an on-axis position which approximately simultaneously changes the on/off state of the display module. The mirror assembly and display and adjustment may utilize aspects of the mirror assemblies described in U.S. Pat. No. 9,205,780, which is hereby incorporated herein by reference in its entirety. 
     The display device may also be controlled or operable in response to an input or signal, such as a signal received from one or more cameras or image sensors of the vehicle, such as a video camera or sensor, such as a CMOS imaging array sensor, a CCD sensor or the like, and image processors or image processing techniques, such as utilizing aspects of the cameras and image processors described U.S. Pat. Nos. 5,550,677; 5,670,935; 5,760,962; 6,498,620; 6,396,397; 6,222,447; 6,201,642; 6,097,023; 5,877,897; 5,796,094; 5,715,093; 6,922,292; 6,757,109; 6,717,610; 6,590,719; 6,320,176; 6,559,435; 6,831,261; 6,806,452; 6,822,563; 6,946,978; 7,038,577; 7,004,606 and/or 7,720,580, and/or U.S. Pat. Pub. Nos. US-2006-0171704; US-2009-0244361 and/or US-2010-0214791, and/or International Publication Nos. WO 2009/046268 and/or WO 2009/036176, which are all hereby incorporated herein by reference in their entireties, or from one or more imaging systems of the vehicle, such as a reverse or backup aid system, such as a rearward directed vehicle vision system utilizing principles disclosed in U.S. Pat. Nos. 5,550,677; 5,760,962; 5,670,935; 6,201,642; 6,396,397; 6,498,620; 6,717,610 and/or 6,757,109, which are hereby incorporated herein by reference in their entireties, a trailer hitching aid or tow check system, such as the type disclosed in U.S. Pat. No. 7,005,974, which is hereby incorporated herein by reference in its entirety, a cabin viewing or monitoring device or system, such as a baby viewing or rear seat viewing camera or device or system or the like, such as disclosed in U.S. Pat. Nos. 5,877,897 and/or 6,690,268, which are hereby incorporated herein by reference in their entireties, a video communication device or system, such as disclosed in U.S. Pat. No. 6,690,268, which is hereby incorporated herein by reference in its entirety, and/or the like. The imaging sensor or camera may be activated and the display screen may be activated (and the mirror head may rotate or pivot to the display mode or position) in response to the vehicle shifting into reverse, such that the display screen is viewable by the driver and is displaying an image of the rearward scene while the driver is reversing the vehicle. It is envisioned that an image processor or controller (such as an EyeQ™ image processing chip available from Mobileye Vision Technologies Ltd. of Jerusalem, Israel, and such as an image processor of the types described in International Pub. No. WO 2010/099416, which is hereby incorporated herein by reference in its entirety) may process image data captured by the rearward facing camera to assess glare lighting conditions (such as to detect headlights of following vehicles that may cause glare at the interior and/or exterior rearview mirror assemblies of the equipped vehicle), and the controller may adjust or control the dimming of the electro-optic mirror assembly or assemblies of the equipped vehicle responsive to such image processing. 
     Because the display screen may be active for prolonged periods of time, the mirror head and/or display screen or module preferably includes heat dissipating means, such as a heatsink or the like. Optionally, the housing may comprise a heat reducing or heat dissipating material, such as aluminum, plastic and/or magnesium or the like. 
     The mirror assembly may also include user actuatable inputs operable to control any of the accessories of or associated with the mirror assembly and/or an accessory module or the like. The user input may incorporate one or more touch or proximity sensitive user inputs and associated icons or the like so a user can readily identify the purpose or function of the user inputs and actuate the appropriate or desired or selected user input. For example, the mirror assembly may include touch sensitive elements or touch sensors or proximity sensors (such as at either or both of the mirror reflective element and the display screen), such as the types of touch sensitive elements described in U.S. Pat. Nos. 5,594,222; 6,001,486; 6,310,611; 6,320,282; 6,627,918; 7,224,324 and/or 7,253,723, and/or International Publication Nos. WO 2012/051500 and/or WO 2013/071070, which are hereby incorporated herein by reference in their entireties, or such as proximity sensors of the types described in U.S. Pat. Nos. 7,224,324; 7,249,860 and/or 7,446,924, and/or International Publication No. WO 2004/058540, which are hereby incorporated herein by reference in their entireties, or such as membrane type switches, such as described in U.S. Pat. No. 7,360,932, which is hereby incorporated herein by reference in its entirety, or such as detectors and the like, such as the types disclosed in U.S. Pat. Nos. 7,255,541; 6,504,531; 6,501,465; 6,492,980; 6,452,479; 6,437,258 and/or 6,369,804, which are hereby incorporated herein by reference in their entireties, and/or the like, while remaining within the spirit and scope of the present invention. 
     Optionally, the user inputs or buttons may comprise user inputs for a garage door opening system, such as a vehicle based garage door opening system of the types described in U.S. Pat.
