Abstract

A display mirror assembly for a vehicle includes a display mirror assembly for a vehicle having a front shield including 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 front shield, display module, and rear shield.

First claim

What is claimed is:

1. A display mirror assembly for a vehicle, comprising:
a housing;
a windshield mounting member extending rearwardly from the housing;
an electro-optic element operably coupled with the housing;
a display module mounted between the electro-optic element and the housing and including a display, the display module being configured to be activated and deactivated; and
an actuator device disposed on the housing and operably coupled with the electro-optic element, wherein the actuator device is adjustable to tilt the electro-optic element in one direction, thereby moving the electro-optic element to an off-axis position which approximately simultaneously changes an activation state of the display module, and wherein the actuator device is also adjustable to tilt the electro-optic element in another direction, thereby moving the electro-optic element to an on-axis position which approximately simultaneously changes the activation state of the display module.

2. The display mirror assembly of claim 1 , further comprising:
a printed circuit board disposed in the housing and operably coupled with the display.

3. The display mirror assembly of claim 2 , further comprising:
an optic block that supports a glare sensor operably coupled with the printed circuit board.

4. The display mirror assembly of claim 2 , further comprising:
an electrical connector having a length sufficient to wrap around the display module and which is operably coupled with the printed circuit board.

5. The display mirror assembly of claim 1 , further comprising:
a partially transmissive graphic overlay on the display module visible on a viewing area when the display mirror assembly is in use.

6. The display mirror assembly of claim 1 , further comprising:
a front shield disposed between the electro-optic element and the display module.

7. The display mirror assembly of claim 1 , further comprising:
a rear shield that shields the display module from radiofrequency radiation.

8. The display mirror assembly of claim 1 , wherein the display has a shape which corresponds to the shape of the electro-optic element, and wherein the display is an LCD, LED, OLED, plasma, or DLP display element.

9. The display mirror assembly of claim 1 , further comprising:
a glare sensor positioned on a rear portion of said vehicle, wherein a signal representative of received light is communicated from the glare sensor to a printed circuit board in the housing.

10. A display mirror assembly for a vehicle, comprising:
a housing;
a glass element operably coupled with the housing;
a display module mounted to the housing operably coupled to a printed circuit board and configured to be activated and deactivated;
a partially transmissive graphic overlay on the display module visible on a viewing area when the display mirror assembly is in use; and
an actuator device operably coupled with the glass element, wherein the actuator device is adjustable to tilt the glass element in a first direction, thereby moving the glass element to an off-axis position which approximately simultaneously changes the activation state of the display module, and wherein the actuator device is also adjustable to tilt the glass element in a second direction, thereby moving the glass element to an on-axis position which approximately simultaneously changes the activation state of the display module.

11. The display mirror assembly of claim 10 , wherein the glass element includes an electro-optic element.

12. The display mirror assembly of claim 10 , wherein the glass element includes a ground edge.

13. The display mirror assembly of claim 10 , wherein the display module includes a display that has a shape which corresponds to the shape of the glass element, and wherein the display is an LCD, LED, OLED, plasma, or DLP display element.

14. A display mirror assembly for a vehicle, comprising:
a display module operably coupled to a partially reflective, partially transmissive electro-optic element and configured to be activated and deactivated; and
an actuator device operably coupled with the partially reflective, partially transmissive electro-optic element, wherein the actuator device is adjustable to tilt the partially reflective, partially transmissive electro-optic element to one of an off-axis and an on-axis position which approximately simultaneously changes an activation state of the display module.

15. The display mirror assembly of claim 14 , further comprising:
a partially transmissive graphic overlay which provides information to a viewer regarding a field of view shown in the display mirror assembly.

16. The display mirror assembly of claim 14 , 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.

17. The display mirror assembly of claim 14 , further comprising:
a housing; and
a printed circuit board operably coupled with an external button disposed on the housing.

18. The display mirror assembly of claim 14 , wherein the partially reflective, partially transmissive electro-optic element includes a ground edge.

19. The display mirror assembly of claim 14 , wherein the display module includes a display that has a shape which corresponds to the shape of the electro-optic element, and wherein the display is an LCD, LED, OLED, plasma, or DLP display element.
