Abstract

A display mirror assembly for a vehicle includes a front shield having a first side and a second side. A partially reflective, partially transmissive element is mounted on the first side. A rear shield is disposed behind the front shield. A display module is mounted between the front shield and the rear shield and includes in order from the front shield: a display; an optic block; a heat sink having an edge lit PCB mounted along a top edge thereof; and a PCB. The front shield is secured to at least one component of the display module with a first retaining feature and the rear shield is secured to at least one component of the display module with a second retaining feature. A housing at least partially surrounds the partially reflective, partially transmissive element, the front shield, carrier plate, display module, and rear shield.

First claim

What is claimed is:

1. A display mirror assembly for a vehicle, comprising:
a front shield configured to block RF radiation and having a forward side and a rearward side, wherein a partially reflective, partially transmissive element is mounted on the forward side;
a rear shield disposed behind the front shield;
a carrier plate disposed between the front shield and the rear shield;
a display module mounted between the front shield and the rear shield and including:
a display;
an optic block disposed behind the display;
a heat sink proximate to the optic block and having an edge lit PCB mounted along a top edge thereof; and
a primary PCB, wherein the front shield is secured to at least one component of the display module with a first retaining feature and the rear shield is secured to at least one component of the display module with a second retaining feature; and

a housing which at least partially surrounds the partially reflective, partially transmissive element, the front shield, carrier plate, display module, and rear shield.

2. The display mirror assembly of claim 1 , wherein the first retaining feature operatively engages the front shield with the optic block, and wherein the second retaining feature operatively engages the rear shield with the heat sink and the optic block.

3. The display mirror assembly of claim 1 , wherein the partially reflective, partially transmissive element is an electrochromic member.

4. The display mirror assembly of claim 3 , wherein the edge of the partially reflective, partially transmissive element has a chrome ring edge treatment.

5. The display mirror assembly of claim 4 , wherein the distance from an outer edge of a front face of the partially reflective, partially transmissive element to an outer edge of a front face of the display module is less than about 9 mm.

6. The display mirror assembly of claim 1 , wherein the display has a shape which corresponds to the shape of the partially reflective, partially transmissive element, and wherein the display is an LCD, LED, OLED, plasma, or DLP display element.

7. The display mirror assembly of claim 1 , further comprising:
a glare sensor optic engaged with the optic block.

8. The display mirror assembly of claim 1 , further comprising:
a partially transmissive graphic overlay which provides information to a viewer regarding the field of view shown in the display mirror assembly.

9. The display mirror assembly of claim 1 , wherein the display module is capable of displaying an image which provides information to a viewer regarding the field of view shown in the display mirror assembly.

10. The display mirror assembly of claim 1 , wherein the primary PCB is electrically coupled with an external bimodal-switch disposed on the housing.

11. A display mirror assembly for a vehicle, comprising:
a front shield configured to block RF radiation and having a first side and a second side, wherein a partially reflective, partially transmissive element is mounted on the first side;
a rear shield disposed behind the front shield;
a display module mounted between the front shield and the rear shield and including in order from the front shield:
a display;
an optic block;
a heat sink having an edge lit PCB mounted along a top edge thereof; and
a primary PCB, wherein the front shield is secured to at least one component of the display module with a first retaining feature and the rear shield is secured to at least one component of the display module with a second retaining feature;

a housing which at least partially surrounds the partially reflective, partially transmissive element, the front shield, display module, and rear shield; and
a bimodal switch operably connected to the partially reflective, partially transmissive element, the bimodal switch operable between a first position and a second position.

12. The display mirror assembly of claim 11 , further comprising:
a glare sensor optic engaged with the optic block.

13. The display mirror assembly of claim 11 , further comprising:
a partially transmissive graphic overlay which provides information to a viewer regarding the field of view shown in the display mirror assembly.

14. The display mirror assembly of claim 11 , wherein the display module is capable of displaying an image which provides information to a viewer regarding the field of view shown in the display mirror assembly.

15. The display mirror assembly of claim 11 , wherein the primary PCB is electrically coupled with the bi-modal switch which extends externally from the housing.

16. A display mirror assembly for a vehicle, comprising:
a front shield having a forward side and a rearward side, wherein a partially reflective, partially transmissive element is mounted on the forward side;
a rear shield disposed behind the front shield;
a carrier plate disposed between the front shield and the rear shield;
a display module mounted between the front shield and the rear shield and including:
a display;
an optic block disposed behind the display;
a heat sink proximate to the optic block and having an edge lit PCB mounted along a top edge thereof; and
a primary PCB, wherein the front shield is secured to at least one component of the display module with a first retaining feature and the rear shield is secured to at least one component of the display module with a second retaining feature; and

a housing which at least partially surrounds the partially reflective, partially transmissive element, the front shield, carrier plate, display module, and rear shield; and
an external bimodal switch disposed on the housing and electrically coupled with the primary PCB.

17. The display mirror assembly of claim 16 , wherein the bimodal-modal switch is configured to at least one of activate or deactivate the display.

18. The display mirror assembly of claim 16 , wherein the bimodal-switch pivots the mirror assembly approximately between 2 degrees and 7 degrees with respect to an occupant.
