Abstract
The present invention relates to information display assemblies and various covert displays using the same.
Claims30
A rearview mirror assembly, comprising:
- an information display at least partially positioned behind a reflective element with respect to an anticipated viewer;
- said information display comprising a negative mode, backlit, liquid crystal display having at least two characters, each of said characters has individual backlighting associated therewith, wherein said backlighting of a given character is controllable independent of backlighting of any other character.
An information display, comprising:
- a liquid crystal display having at least two characters with each character having associated backlighting;
- and
- a display driver having more outputs than said liquid crystal display has characters, wherein at least one output of said display driver is used to control said backlighting.
A rearview mirror assembly, comprising:
- a backlit liquid crystal display positioned behind an automatically dimming reflective element, wherein the intensity of said backlit liquid crystal display is a function of the reflectivity of said automatically dimming reflective element.
An information display, comprising:
- a diffuser positioned between a backlit liquid crystal display and backlighting associated with said liquid crystal display, wherein said diffuser redirects light rays emitted by said backlighting as a function of at least one of the following;
- the position of said liquid crystal display relative to at least one anticipated viewer and a planar surface of said diffuser relative to a viewing angle of at lest one anticipated viewer.
A rearview mirror assembly, comprising:
- an information display at least partially positioned behind a reflective element with respect to an anticipated viewer;
- said information display comprising a negative mode, backlit, liquid crystal display having at least two characters, each of said characters has individual backlighting associated therewith, wherein said backlighting of a given character is controllable independent of backlighting of any other character;
- a display driver having more outputs than said liquid crystal display has characters, wherein at least one output of said display driver is used to control said backlighting;
- and
- a diffuser positioned between a backlit liquid crystal display and backlighting associated with said liquid crystal display, wherein said diffuser redirects light rays emitted by said backlighting as a function of at least one of the following;
- the position of said liquid crystal display relative to at least one anticipated viewer and a planar surface of said diffuser relative to a viewing angle of at lest one anticipated viewer;
- wherein said reflective element is automatically dimming and the intensity of said backlit liquid crystal display is a function of the reflectivity of said automatically dimming reflective element;
- and
- wherein said reflective element is at least partially transmissive and an optimum light ray wavelength transmission of said reflective element is substantially equal to the predominant wavelength of light rays emitted from said information display.
6 more elements
A rearview mirror assembly, comprising:
- an information display and a reflective element, wherein said reflective element is at least partially transmissive and an optimum light ray wavelength transmission of said reflective element is substantially equal to the predominant wavelength of light rays emitted by said information display.
A rearview mirror assembly, comprising:
- a backlit liquid crystal display positioned behind an automatically dimming reflective element, wherein the intensity of said backlit liquid crystal display is a function of an ambient light sensor.
A rearview mirror assembly, comprising:
- a backlit liquid crystal display positioned behind an automatically dimming reflective element, wherein the intensity of said backlit liquid crystal display is a function of a glare light sensor.
A rearview mirror assembly, comprising:
- a backlit liquid crystal display positioned behind an automatically dimming reflective element, wherein the contrast of said backlit liquid crystal display is a function of an ambient light sensor.
A rearview mirror assembly, comprising:
- a backlit liquid crystal display positioned behind an automatically dimming reflective element, wherein the contrast of said backlit liquid crystal display is a function of an glare light sensor.
