Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise. 
         [0027]    The terms “including,” “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises a . . . ” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element. 
         [0028]    Referring now to  FIGS. 1-3 , reference numeral  10  generally designates a display mirror assembly for a vehicle. The display mirror assembly  10  includes a partially reflective, partially transmissive element  12  (also referred to as a “glass element” herein) and a display module  18  ( FIG. 4 ) that is viewed through the partially reflective, partially transmissive element  12 . As shown in  FIG. 4 , the display mirror assembly  10  further includes a bezel  13  integrally coupled with a front shield  14 . As shown in  FIGS. 4-5 , the display module  18  generally includes several components, including a display  22 , an optic block  24 , a heat sink  26 , a light emitting diode (LED) printed circuit board, and a primary printed circuit board  28 . A housing  30  at least partially receives the bezel  13 , the display module  18 , and the rear shield  16 , and includes a mounting member  32  extending rearwardly therefrom. The mounting member  32  is adapted for mounting on a windshield or a headliner of a vehicle. 
         [0029]    Referring generally to  FIGS. 1-4 , the display mirror assembly  10  has a viewing area  40 , which includes a front surface  42  of the glass element  12 . The viewing area  40  may be a rectangular shape, a trapezoidal shape, or any custom contoured shape desired for aesthetic reasons. A second surface of the glass element  12  may include a peripheral hiding layer, such as a chrome ring edge treatment. 
         [0030]    Referring to  FIG. 4 , the display mirror assembly  10  for a vehicle is shown, with the components partially exploded. The display mirror assembly  10  includes the glass element  12  which is attached to the bezel  13 . The bezel  13  is integrally coupled with the front shield  14 . The front shield  14  and the bezel  13  support the display module  18 , the rear housing  30 , and the mounting member  32 . As shown in  FIGS. 4 and 5 , the components of the display module  18  include various retaining features to operably connect the several components of the display module  18  with the front shield  14 , the bezel  13  and each other, and to provide support to the display module  18 . Specifically, the bezel  13  includes retaining features to operably connect the bezel  13  to the display module  18 , and the rear shield  16  has retaining features  44  to operably connect the rear shield  16  to the display module  18 . The retaining features  44  generally include snap fit connections, tab and slot connections, heat stake connections, screw connections, and other known retaining features. Some or all of the retaining features may also be strengthened by the addition of adhesive compounds. Certain non-limiting illustrative examples of retaining features are described in detail herein. 
         [0031]    The display mirror assembly  10  will hereafter be described in greater detail, beginning with the elements closest to the intended viewer, and extending rearwardly away from the viewer. 
         [0032]    The glass element  12  may be an electro-optic element or single transflective or an element such as a prism. For electro-optic element constructions, the glass element  12  may include a front substrate and a rear substrate. One non-limiting example of an electro-optic element includes an electrochromic medium, which includes at least one solvent, at least one anodic material, and at least one cathodic material disposed between the first substrate and the rear substrate. Typically, both of the anodic and cathodic materials are electroactive and at least one of them is electrochromic. It will be understood that regardless of its ordinary meaning, the term “electroactive” will be defined herein as a material that undergoes a modification in its oxidation state upon exposure to a particular electrical potential difference. Additionally, it will be understood that the term “electrochromic” will be defined herein, regardless of its ordinary meaning, as a material that exhibits a change in its extinction coefficient at one or more wavelengths upon exposure to a particular electrical potential difference. Electrochromic components, as described herein, include materials whose color or opacity are affected by electric current, such that when an electrical current is applied to the material, the color or opacity change from a first phase to a second phase. The electrochromic component may be a single-layer, single-phase component, multi-layer component, or multi-phase component, as described in U.S. Pat. No. 5,928,572 entitled “Electrochromic Layer And Devices Comprising Same,” U.S. Pat. No. 5,998,617 entitled “Electrochromic Compounds,” U.S. Pat. No. 6,020,987 entitled “Electrochromic Medium Capable Of Producing A Pre-selected Color,” U.S. Pat. No. 6,037,471 entitled “Electrochromic Compounds,” U.S. Pat. No. 6,141,137 entitled “Electrochromic Media For Producing A Pre-selected Color,” U.S. Pat. No. 6,241,916 entitled “Electrochromic System,” U.S. Pat. No. 6,193,912 entitled “Near Infrared-Absorbing Electrochromic Compounds And Devices Comprising Same,” U.S. Pat. No. 6,249,369 entitled “Coupled Electrochromic Compounds With Photostable Dication Oxidation States,” and U.S. Pat. No. 6,137,620 entitled “Electrochromic Media With Concentration Enhanced Stability, Process For The Preparation Thereof and Use In Electrochromic Devices”; U.S. Pat. No. 6,519,072, entitled “Electrochromic Device”; and International Patent Application Serial Nos. PCT/US98/05570 entitled “Electrochromic Polymeric Solid Films, Manufacturing Electrochromic Devices Using Such Solid Films, And Processes For Making Such Solid Films And Devices,” PCT/EP98/03862 entitled “Electrochromic Polymer System,” and PCT/US98/05570 entitled “Electrochromic Polymeric Solid Films, Manufacturing Electrochromic Devices Using Such Solid Films, And Processes For Making Such Solid Films And Devices,” all of which are herein incorporated by reference in their entirety. The glass element  12  may also be any other element having partially reflective, partially transmissive properties. To provide electric current to the glass element  12 , electrical elements are provided on opposing sides of the element, to generate an electrical potential therebetween. A J-clip may be electrically engaged with each electrical element, and element wires may extend from the J-clips to the primary printed circuit board  28 . 
         [0033]    Now referring to  FIGS. 1-5 , the front shield  14  of the bezel  13  functions to shield the display module  18  from emitting radio frequency (RF) electromagnetic radiation and provide electromagnetic-immunity and to provide support for the glass element  12  and the display module  18 . The bezel  13  is disposed about a periphery of the glass element  12  and configured to retain the glass element  12  against the display module  18 , wherein the front shield  14  is integrally coupled with the bezel  13 . The front shield  14  is formed from one or more materials which are suitable to block RF radiation, including without limitation steel. As a non-limiting example, the front shield  14  can be formed from a stamped steel material which is about 0.5 mm thick. A central peripheral wall  46  is positioned adjacent the bezel  13  and the front shield  14 . The central peripheral wall  46  is configured to abut a rear surface of the glass element  12 . The bezel  13  includes a rounded peripheral edge  48  that closely receives the glass element  12 . A back side of the central peripheral wall  46  is in close proximity to, or in abutment with, the display  22 . 
         [0034]    With reference again to  FIGS. 4 and 5 , the front shield  14  of the bezel  13  may take on a variety of constructions designed to minimize or eliminate RF electromagnetic radiation from penetrating through the glass element  12  of the display mirror assembly  10 . At the same time, the front shield  14  of the bezel  13  together define a composite that prevents or minimizes RF electromagnetic radiation generated by the display  22  or other components inside the housing  30  from leaving the housing  30 . As previously noted, the front shield  14  may be formed from a variety of materials. The same is true of the bezel  13 . It is generally contemplated that the bezel  13  and the front shield  14  may be formed from different materials to form a composite structure. For example, the bezel  13  may be constructed from a polymeric material that is injection molded over the front shield  14 , which may be constructed from a metallic material. Additionally, it is generally contemplated that the central peripheral wall  46 , which extends inwardly from the bezel  13 , may be formed as part of the bezel  13  or the front shield  14 . The central peripheral wall  46  provides structural rigidity to the bezel  13 , and may also assist in minimizing RF electromagnetic radiation from penetrating or escaping the display mirror assembly  10 . The central peripheral wall  46  also constitutes a locating feature to ensure that the glass element  12  is positioned at the right depth relative to the bezel  13 . Accordingly, the glass element  12  can be positioned to slightly protrude forward of the bezel  13 , flush with a forward peripheral edge of the bezel  13 , or be slightly recessed a front edge of the bezel  13 . 
         [0035]    As illustrated in  FIGS. 6-9 , the peripheral edge  48  of the bezel  13  closely receives the glass element  12 , and also includes a shape that is complementary to the glass element  12 . The bezel  13  also includes a chin  41  on a lower portion thereof. The chin  41  may support a light sensor, one or more buttons that activate functionality inside the display mirror assembly  10 , a microphone, etc. The chin may extend over a lower forward portion of the housing  30 , or may be received into a lower portion of the housing  30 . A periphery of the bezel  13  also includes locating features  51 , as well as attachment features  54 , which may include snap-fit connectors, mechanical fasteners, etc. The attachment features  54  are generally configured for engagement with complementary attachment features  56  disposed on an inside wall of the housing  30 . 
         [0036]    With reference now to  FIGS. 9-12 , the bezel  13  and front shield  14  combination includes a variety of features. Specifically, the front shield includes a set of retaining tabs for engagement with the display module and the bezel  13  includes locating features in the form of recesses  43  defined in a peripheral wall  45  of the bezel  13 . The peripheral wall  45  extends about each of four internal sides of the bezel  13 . In the illustrated embodiment, the recesses  43  are in the form of partially arcuate recesses configured to receive complementary protuberances  43 A extending from lateral walls  45 A of the front shield  14 . In the illustrated embodiment, the protuberances  43 A are arcuate protuberances that generally define a portion of a cylinder. The protuberances  43 A are configured to include a radius that is the same as, or slightly less than, the radius of the recesses  43 . Accordingly, during engagement of the front shield  14  with the bezel  13 , overmolded plastic locks the front shield  14  to the bezel  13 . Notably, the peripheral wall  45  of the bezel  13  is generally continuous. The lateral wall  45 A of the front shield  14 , as illustrated, includes separate wall portions on each of the four sides of the front shield  14 . However, it will be understood that the lateral wall  45 A of the front shield  14  may be separated, as illustrated, or may be continuous, similar to the design illustrated for the bezel  13 . The chin  41  includes an aperture  47  configured to receive one of a button, a sensor, a microphone, etc. In addition, the lateral wall  45 A of the bezel  13  includes engagement features  49  configured to receive engagement features  49 A of the front shield  14 . It is generally contemplated that these features may be used to secure light sensors, or other components utilized by the display mirror assembly  10 . 
         [0037]    Additionally, the peripheral wall  46  includes a plurality of attachment features configured to engage with one or more of the display  22 , the optic block  24 , the heat sink  26 , the primary printed circuit board  28 , the rear shield  16 , and the housing  30 . The attachment features may include friction-fit designs, snap-fit configurations, etc. It is also generally contemplated that mechanical fasteners or an adhesive may be used to secure the components references above. 
         [0038]    With reference again to  FIGS. 4 and 5 , the display module  18  is disposed behind the front shield  14 , with the display  22  viewable through the opening in the front shield  14 . The components of the display module  18  are ordered, from the front shield  14  toward the rear shield  16 , the display  22 , the optic block  24 , the heat sink  26 , and the primary printed circuit board  28 . 
         [0039]    The display  22  may be liquid crystal display (LCD), LED, organic light emitting diode (OLED), plasma, digital light processing (DLP), or other display technology. The display  22  further includes a flexible electrical connector  50 , which is operably mechanically and electrically connected with the primary printed circuit board  28 . The flexible electrical connector  50  has a length L which is sufficient to wrap around the display module  18  components between the display  22  and the primary printed circuit board  28 , and has a width which extends substantially along a top edge  52  of the display  22 . The flexible electrical connector, when operably coupled to the primary printed circuit board  28 , aids in securing the components along a top edge of the display module  18 . 
         [0040]    With reference again to  FIG. 4 , a glare sensor  60  is provided on the front side of the printed circuit board  28 , in a location which receives light through the bezel  13 , and which is not behind the display  22 . A glare sensor lens  61  is snap-fit into the aperture  47  in the bezel  13 . A glare sensor  60  receives light from headlamps of a trailing vehicle, and measures information regarding the likely glare visible on the glass element  12  and communicates this information to the display mirror assembly  10  so that the display mirror assembly  10  can be optimized to allow viewing of the display  22  through the glass element  12 . The vertical/horizontal pattern of the glare sensor  60  is symmetrical, so that orientation of the glare sensor  60  is not significant. The glare sensor  60  could also be packaged at least partially within the housing  30  of the display mirror assembly  10  and have a light guide which is configured to propagate light to the glare sensor  60 . The glare sensor  60  could also be an imager on a rear portion of the vehicle, wherein a signal representative of the received light is communicated from the glare sensor  60  to the display mirror assembly  10 . An ambient light sensor  63  may also be operably coupled with the printed circuit board  28  and includes a secondary lens  65 . 
         [0041]    The heat sink  26  is disposed rearwardly from the optic block  24 , and dissipates heat generated by the LED printed circuit board  28  and other components of the primary printed circuit board  28 . The heat sink  26  has a generally planar body  70  with a front side  72  and a top edge  74 . 
         [0042]    The primary printed circuit board  28  operates to provide electrical power and control for the components of the display module  18  and for the glass element  12 . As shown in  FIGS. 4 and 5 , the primary printed circuit board  28  is generally planar, with a front side  80 , a rear side  82 , and side edges  84 . The front side  80  is facing the heat sink  26  and the rear side  82  is facing the rear shield  16 . Electrical components are generally oriented on both sides of the primary printed circuit board  28 . The primary printed circuit board  28  includes an electrical connector for operable electrical engagement with the electrical element wires of the glass element  12 , an electrical connector for operable electrical engagement with the flexible electrical connector  50 , and an electrical connector  92  for operable electrical engagement with a wiring harness  94 . Additional functional elements that may be provided on the display mirror assembly  10  may also be electrically connected to the primary printed circuit board  28 , such as the glare sensor  60  and any other functional buttons or features of the display mirror assembly  10 . The primary printed circuit board  28  further includes side cutouts  96  along the side edges  84 , to permit passage of the mechanical fasteners used to secure the rear shield  16  to the components of the display module  18 . 
         [0043]    The rear shield  16  functions to shield the printed circuit board  28  from emitting RF radiation. The rear shield  16  also serves to encapsulate the display module  18 , and further interlock the components of the display mirror assembly  10 . The rear shield  16  is formed from a material which is suitable to block such radiation and provide the desired support for the display mirror assembly  10 , such as steel. As a non-limiting example, the rear shield  16  can be formed from stamped steel. 
         [0044]    The rear housing  30  includes a forwardly directed cavity  100 , into which all or a portion of the front shield  14 , rear shield  16 , and the display module  18  are received and supported therein. The rear housing  30  includes mechanically engaging features  102  which snap fit with corresponding engagement features  51  of the bezel  13 , which are located above locating features  104  on a peripheral wall  106  of the rear shield  16 . Alternatively, the mechanically engaging features  102  may engage any of the display module components, such as the heat sink  26 . The mounting member  32  is operably engaged with the rear housing  30  in any known manner. 
         [0045]    With reference again to  FIGS. 4 and 5 , a mounting assembly is configured to extend through a rear wall of the housing  30  and into secure engagement with an internal support  107 . A plurality of fasteners  108  secure the internal support  107  with the mount  105 . Accordingly, the entire display mirror assembly  10  can be supported on the windshield of a vehicle. Notably, an externally-extending wire harness  109  is routed through barrel  111  of the mount  105 , or may be routed around or outside of the barrel  111 . A camera harness is mounted outside of the mount  105 , but could be routed through the barrel  111 . 
         [0046]    With respect to the following description, the display mirror assembly  10  is considered “on axis” when a line perpendicular to the plane of the glass element  12  extends toward the eyes of a viewer. Due to the display  22  being viewed through the glass element  12 , any glare on the glass element  12  may interfere with the visibility of the display  22 . When the display mirror assembly  10  is on axis and is being used during night time driving conditions, headlights from a trailing vehicle (i.e., a vehicle driving behind the vehicle with the display mirror assembly  10 ) can cause a glare which is visible to the driver. 
         [0047]    According to one embodiment of the present disclosure, an actuator device  110 , as shown in  FIGS. 13 and 13A , is operably coupled to the display mirror assembly  10 . When actuated, as shown in  FIGS. 14 and 14A , the actuator device  110  moves at least the glass element  12  off axis (i.e., away from a direct line toward the driver&#39;s eyes). Typically, actuation of the actuator device  110  tilts the glass element  12  upwards, to move the glass element  12  to an off-axis position. However, it should be appreciated that the actuator device  110  can be configured to move the glass element  12  in any direction with respect to the axis. The actuator device  110  can also be configured to move the display  22  upon activation. The actuator device  110  can also be configured to turn the display  22  on or off. Thus, when the actuator device  110  is actuated to move the glass element  12  off axis, the display  22  can be turned on. 
         [0048]    As illustrated in  FIGS. 4A and 13-14A , the actuator device  110  includes an actuator  112  and an abutment member  114  configured to adjust the angular position of the glass element  12  relative to the eyes of a viewer. As the actuator  112  is adjusted, the abutment  114  moves the glass element  12  and possibly the display  22  as well, such that glare on the glass element  12  can be minimized, redirected, or eliminated. 
         [0049]    Additionally, to provide information to the viewer of the display mirror assembly  10 , the display mirror assembly  10  may include information regarding the field of view, such as a partially transmissive graphic overlay or an image on the display  22  visible on the viewing area  40  when the display mirror assembly  10  is in use. 
         [0050]    The forwardly directed cavity of the rear housing  30  is placed over the bezel  13 , and the mechanically engaging features of the rear housing  30  are snap fit to engage with the corresponding engagement feature of the bezel  13 . The mounting member  32  may be installed in the rear housing  30  prior to assembly. 
         [0051]    The present disclosure may be used with a glass element such as that described in U.S. Pat. Nos. 9,174,577; 8,925,891; 8,814,373; 8,201,800; and 8,210,695; U.S. Patent Application Publication No. 2012/0327234; and U.S. Provisional Patent Application Nos. 61/709,716; 61/707,676; and 61/704,869, which are hereby incorporated herein by reference in their entirety. Further, the present disclosure may be used with a rearview packaging assembly such as that described in U.S. Pat. Nos. 8,885,240; 8,814,373; 8,646,924; 8,643,931; and 8,264,761; and U.S. Provisional Patent Application Nos. 61/707,625; and 61/590,259, which are hereby incorporated herein by reference in their entirety. Additionally, it is contemplated that the present disclosure can include a bezel such as that described in U.S. Pat. Nos. 8,827,517; 8,210,695; and 8,201,800, which are hereby incorporated herein by reference in their entirety. 
         [0052]    A display mirror assembly according to the present disclosure has several advantages. The display module is supported between the bezel and housing, and does not require an additional support or carrier plate. Omission of a carrier plate, and inclusion of retaining features in the front shield and rear shield, permits the display mirror assembly to be lighter, involve less parts for manufacturing, and to have a display which is viewable over a larger percentage of the total viewing area of the display mirror assembly. For mirror applications with one or more mirror-based accessories, the accessory or accessories may be received in or disposed at or in the mirror casing and/or may be disposed at the mounting structure of the mirror assembly. 
         [0053]    The present disclosure may also include a frameless mirror assembly that has a reflective element adhered or attached to a front or mounting surface of a mirror casing or bezel having a configuration that generally defines a peripheral support. The peripheral support may be externally exposed or hidden within the housing behind the glass element  12 . In this instance, the peripheral support does not encompass a perimeter edge region of the front surface of the reflective element. In configurations where the glass element  12  is an electro-optic element, then a peripheral edge of the front substrate can be exposed and not covered by the peripheral support. The rear substrate may or may not be concealed by the peripheral support. The peripheral support may extend behind the glass element  12  between the forward peripheral edge of the housing and a rear side of the front substrate. Alternatively, the peripheral support could be positioned behind the rear substrate within the housing. The flush front surface of the reflective element and peripheral support provides a frameless, and more modern appearance to the mirror assembly. Also, the opaque perimeter border band and peripheral support may contrast or match to further enhance the appearance, depending on the application and desired appearance of the mirror assembly. For example, the opaque border band may include a metallic appearance or may be light absorbing and thus may have a dark color, while the peripheral support may be a dark or black colored plastic or may be chrome plated or otherwise colored to provide the desired or selected appearance of the mirror assembly. It is also contemplated that a distance from a peripheral edge of the display to the housing may be less than 11 mm. Alternatively, a distance from a peripheral edge of the display to a forward peripheral edge of the housing may be less than 6.5 mm, or a distance from a peripheral edge of the display to the housing may be less than 3.0 mm. 
         [0054]    It will be appreciated that embodiments of the disclosure described herein may be comprised of one or more conventional processors and unique stored program instructions that control one or more processors to implement, in conjunction with certain non-processor circuits, some, most, or all of the functions of a display mirror assembly  10 , as described herein. The non-processor circuits may include, but are not limited to signal drivers, clock circuits, power source circuits, and/or user input devices. As such, these functions may be interpreted as steps of a method used in using or constructing a classification system. Alternatively, some or all functions could be implemented by a state machine that has no stored program instructions, or in one or more application specific integrated circuits (ASICs), in which each function or some combinations of certain of the functions are implemented as custom logic. Of course, a combination of the two approaches could be used. Thus, the methods and means for these functions have been described herein. Further, it is expected that one of ordinary skill, notwithstanding possibly significant effort and many design choices motivated by, for example, available time, current technology, and economic considerations, when guided by the concepts and principles disclosed herein will be readily capable of generating such software instructions and programs and ICs with minimal experimentation. 
         [0055]    It will be understood by one having ordinary skill in the art that construction of the described disclosure and other components is not limited to any specific material. Other exemplary embodiments of the disclosure disclosed herein may be formed from a wide variety of materials, unless described otherwise herein. 
         [0056]    For purposes of this disclosure, the term “coupled” (in all of its forms, couple, coupling, coupled, etc.) generally means the joining of two components (electrical or mechanical) directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two components (electrical or mechanical) and any additional intermediate members being integrally formed as a single unitary body with one another or with the two components. Such joining may be permanent in nature or may be removable or releasable in nature unless otherwise stated. 
         [0057]    It is also important to note that the construction and arrangement of the elements of the disclosure as shown in the exemplary embodiments is illustrative only. Although only a few embodiments of the present innovations have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter recited. For example, elements shown as integrally formed may be constructed of multiple parts or elements shown as multiple parts may be integrally formed, the operation of the interfaces may be reversed or otherwise varied, the length or width of the structures and/or members or connector or other elements of the system may be varied, the nature or number of adjustment positions provided between the elements may be varied. It should be noted that the elements and/or assemblies of the system may be constructed from any of a wide variety of materials that provide sufficient strength or durability, in any of a wide variety of colors, textures, and combinations. Accordingly, all such modifications are intended to be included within the scope of the present innovations. Other substitutions, modifications, changes, and omissions may be made in the design, operating conditions, and arrangement of the desired and other exemplary embodiments without departing from the spirit of the present innovations.
