Abstract
A display mirror assembly for a vehicle includes a housing configured for attachment to the vehicle; a prismatic element positioned in the housing; a partially reflective, partially transmissive coating provided on a rear surface of the prismatic element; a display mounted behind the prismatic element within the housing; and an actuator device for moving the prismatic element between three distinct viewing positions including a first viewing position, a second viewing position wherein the prismatic element is tilted higher than in the first viewing position, and a third viewing position wherein the prismatic element is tilted higher than in the second viewing position.
Claims19
A display mirror assembly for a vehicle, comprising:
- a housing configured for attachment to a vehicle;
- a prismatic element positioned in said housing;
- a partially reflective, partially transmissive coating provided on a rear surface of said prismatic element;
- a display mounted behind said prismatic element within said housing;
- and
- an actuator device for moving said prismatic element between three distinct viewing positions including a first viewing position, a second viewing position wherein said prismatic element is tilted higher than in the first viewing position, and a third viewing position wherein said prismatic element is tilted higher than in the second viewing position, wherein said display is automatically turned on in response to said prismatic element moving into the third viewing position and is automatically turned off in response to said prismatic element moving into the first or second viewing positions.
A display mirror assembly for a vehicle, comprising:
- a housing configured for attachment to a vehicle;
- a prismatic element positioned in said housing;
- a partially reflective, partially transmissive coating provided on a rear surface of said prismatic element;
- a display mounted behind said prismatic element within said housing;
- and
- an actuator device for moving said prismatic element between three distinct viewing positions including a first viewing position, a second viewing position and a third viewing position,
- wherein a primary reflected image of a rearward scene is reflected from said partially reflective, partially transmissive coating and a secondary reflected image of the rearward scene is reflected from a front surface of said prismatic element at a different angle than the primary reflected image, the primary reflected image having a greater intensity than the secondary reflected image,
- wherein:
- when in the first viewing position, said prismatic element is positioned to reflect the primary reflected image towards a viewer's eyes,
- when in the second viewing position, said prismatic element is positioned to reflect the secondary reflected image towards the viewer's eyes,
- when in the third viewing position, said prismatic element is positioned such that a reflected image of a headliner of the vehicle is reflected towards the viewer's eyes and neither the primary nor secondary reflected images are reflected towards the viewer's eyes, and
- said display is turned on when said prismatic element is in the third viewing position and is turned off when said prismatic element is in the first or second viewing positions.
A display mirror assembly for a vehicle, comprising:
- a housing configured for attachment to a vehicle;
- a prismatic element positioned in said housing;
- a reflective coating provided on a rear surface of said prismatic element, said reflective coating having a transmissive region through which light may pass;
- a display mounted behind said prismatic element within said housing behind said transmissive region so as to project light therethrough;
- and
- an actuator device for moving said prismatic element between three distinct viewing positions including a first viewing position, a second viewing position wherein said prismatic element is tilted higher than in the first viewing position, and a third viewing position wherein said prismatic element is tilted higher than in the second viewing position,
- wherein said display is turned on when said prismatic element is in the third viewing position and is turned off when said prismatic element is in the first or second viewing positions.
