WAVEGUIDE MIRROR DISPLAY SYSTEM
First Claim
1. A vehicle display system, comprising:
- an electro-optic device comprising;
a first substantially transparent substrate having first and second surfaces disposed on opposite sides thereof, wherein at least one of the first and second surfaces comprises a first electrically conductive layer;
a second substantially transparent substrate having third and fourth surfaces disposed on opposite sides thereof, wherein at least one of the third and fourth surfaces comprises a second electrically conductive layer;
an electro-optic medium disposed in a cavity formed between the first substantially transparent substrate and the second substantially transparent substrate, the electro-optic medium being variably transmissive;
a substantially transparent display disposed adjacent to the electro-optic device;
at least one display driver configured to display image data on the substantially transparent display; and
a controller in communication with the electro-optic device and the at least one display driver, wherein the controller is operable to;
control a transmission state of the electro-optic device between a transparent state and an opaque state; and
control the display driver to display the image data on the substantially transparent display.

Abstract
A vehicle display system is disclosed. The system comprises an electro-optic device configured to switch between a mirror state and a light-transmissive state. The electro-optic device comprises a first substrate and a second substrate forming a cavity. The cavity is configured to retain an electro-optic medium that is variably transmissive such that the electro-optic device is operable between substantially clear and darkened states. The system further comprises a substantially transparent display disposed adjacent to the electro-optic device. The electro-optic device is converted to the darkened state when the substantially transparent display is emitting light.

20. A vehicle display apparatus, comprising:
-
an electrochromic device comprising a reflective element, wherein the reflective element is configured to reflect a reflected view of a rearward directed field of view from the vehicle; a substantially transparent display disposed adjacent to the electro-optic device; at least one display driver configured to display image data on the substantially transparent display; and a controller in communication with the electro-optic device and the at least one display driver, wherein the controller is operable to; control the electro-optic element to selectively control a mirror state and the substantially transparent state of the electrochromic device in response to the transmission state of the electro-optic element; and control the display driver to display the image data on the substantially transparent display.
