Abstract
A method including the determination of a contrast ratio based on a luminance level and an ambient light associated with a display device, the adjustment of a light based on the contrast ratio, wherein the light is emitted from a front light guide, and the direction of the adjusted light toward a driver associated with a vehicle, wherein directing the adjusted light toward the driver causes the display device to display an image more visibly to a passenger associated with the vehicle than the driver.
Claims20
A method, comprising:
- determining, based on a luminance level and an ambient light associated with a display device, a contrast ratio;
- adjusting, based on the contrast ratio, a light, wherein the light is emitted from a front light guide;
- and
- directing the adjusted light toward a driver associated with a vehicle, wherein directing the adjusted light toward the driver causes the display device to display an image more visibly to a passenger associated with the vehicle than the driver.
A system comprising:
- a controller configured to:
- determine, based on a luminance level and an ambient light associated with a display device, a contrast ratio,
- adjust, based on the contrast ratio, a light, wherein the light is emitted from a front light guide, and
- cause the adjusted light to be directed toward a driver associated with a vehicle, wherein directing the adjusted light toward the driver causes the display device to display an image more visibly to a passenger associated with the vehicle than the driver;
- and
- a front light guide configured to:
- direct the adjusted light toward the driver.
One or more non-transitory computer-readable media storing processor-executable instructions that, when executed by at least one processor, cause the at least one processor to:
- determine, based on a luminance level and an ambient light associated with a display device, a contrast ratio;
- adjust, based on the contrast ratio, a light, wherein the light is emitted from a front light guide;
- and
- direct the adjusted light toward a driver associated with a vehicle, wherein directing the adjusted light toward the driver causes the display device to display an image more visibly to a passenger associated with the vehicle than the driver.
